🚨 The first existential IPO

An investment newsletter calls Anthropic’s leaked S-1 the first IPO prospectus that openly prices existential AI risk into a growth story. Cited figures include an $8B operating loss and $42B net loss for 2025, plus about $518B in compute commitments over 7–10 years with roughly 80% uncancellable. The author expects profit in 2026 and annualized revenue over $100B by year-end 2026, with a November listing rumor.

Every technology platform reaches a moment in its lifecycle when startups prepare to enter the public markets. Anthropic seems set to go public first, and yesterday Reuters got hold of a copy of its IPO prospectus, the S-1. We sent an analysis out for readers of the AI Investment Brief by Exponential View earlier today, sharing some of our forecasts into 2026. Here is the headline: the S-1 shows a business investing for growth, with the first signs of green shoots. Beyond the astonishing headline numbers- an $8bn operating loss for 2025 and a net loss of $42bn (bumped up by an accounting charge)- what do we see? It is a business whose revenues are growing far faster than its costs. This trend will continue into 2026, when the company will likely turn a profit. We dig into this more here. The company is nothing if not ambitious. It has $518bn in compute commitments over 7-10 years. About 80% of these, c $410bn, cannot be cancelled. Assuming Anthropic wants a decent margin, that means a trillion bucks give or take in sales over that period. Big numbers, but Anthropic’s annualised revenues will exceed $100bn by the end of 2026. The rumour mill suggests Anthropic will go public in November.

OpenAI DevDay 2026 live blog

OpenAI’s DevDay keynote centered on Dots, a personal always-on agent, plus cheaper and faster model tiers for builders. Dots are powered by Astra, ship today for ChatGPT Pro and Enterprise, and come with shared ChatGPT Spaces and Slack identities. GPT-6.1 Sol is pitched as near-Astra intelligence at about one-fifth the price; Ultrafast claims up to 300 tokens per second at 6× standard price. Also previewed: a Decisions API with predefined options, open Codex harness / cloud Codex, and Codex Security Cloud with Daybreak Blue scans.

Notes
  • Source: Simon Willison live blog from Fort Mason, free creator-area ticket.
  • Dots: Muse-like personal agent; name + blob avatar; voice-heavy demos; powered by Astra (“most aligned model”); ChatGPT Space for team collaboration (shared artifacts); Dots in Slack with own identities; specialist dots (legal/finance) + Microsoft 365 collaboration mentioned. Pro + Enterprise access today.
  • Live demo hiccup: “Dottie is having a slow morning” / still checking.
  • GPT-6.1 Sol: near-Astra at ~1/5 price; launching today. Ultrafast: 8× faster, up to 300 tok/s, 6× price of standard; Astra 6 today, Sol 6.1 soon. Pro 500 plan for Ultrafast + 25× Plus usage; $200/mo plan back on sale.

OpenAI DevDay 2026 live blog 29th September 2026 I’m at OpenAI DevDay today, in Fort Mason, San Francisco. Same as last year I’ll be live blogging the keynote and some other notes during the day. OpenAI gave me a free ticket and a seat in the “creator” area for the keynote. 09:27 I'm in the room for the keynote, which starts in half an hour. This year I vibe-coded a system for more easily adding photos to my live blog. I intended to do that using Codex Cloud (I built it on my phone on the way to the venue) but ran into problems with that and switched to Claude Code for web instead. 10:01 Sam Altman is on stage, welcoming us to DevDay. He promises "our best DevDay yet". 10:02 Showing features they've shipped that people asked for. Codex on Linux and Codex on your phone both got some applause. 10:03 Today, a product to feel like a "whole new way of working with AI". My guess is that it's a personal agent similar to Muse... 10:03 10:03 It's called "Dots". 10:05 It does look very Muse-like. You get to pick its name, then it's represented by a cute blob-like avatar. (My Muse avatar is a pelican.) 10:06 This demo video includes a whole lot of voice interactions, presumably using GPT-Live or a new generation of that technology. 10:06 10:07 Dots are "powered by Astra". That would be an expensive default model! 10:08 A very ambitious use-case, migrating an API. I'm surprised that they went for such a code-heavy price sample so early on, I guess this is a developer audience. 10:09 Sam called Astra "our most aligned model", to allow you to trust your Dot with "as much responsibility as you are comfortable with". 10:09 "You also need a place four your team to collaborate with their Dots". So they are introducing ChatGPT Space. 10:10 These Spaces look like shared artifacts, maybe Google Docs meets the artifacts pattern. Sam Introduces Holly Li. 10:11 Holly is talking through a scenario building fictional music app. Holly has a Dot called "Dottie", which has access to ChatGPT, Slack, Teams, and more. 10:12 This UI really does look like Meta's Muse agent, currently still at number one on the iOS App Store free list. 10:13 Live demo! "Dottie is having a slow morning" - we got a "still checking" and an embarrassing silent moment. 10:14 Now we're in ChatGPT Space. It has a Notion-style slash menu. 10:16 People at OpenAI started delegating to their Dots directly in Slack, which have their own identities in OpenAI Slack. I guess this is OpenAI's answer to Claude Tag. 10:17 "Dottie can use Codex on my laptop to build the app and launch it in the iPhone Simulator." 10:18 ChatGPT Pro and Enterprise customers get access to Dots today. 10:19 10:19 They're also building "specialist dots" for legal, finance, etc. They'll collaborate with enterprises on this, and are also doing a thing with Microsoft 365 around these. 10:20 "The second big part of today" is about platforms. Says says: Great models. Tools - access to the same tools used within OpenAI. And distribution. 10:21 People have been asking for GPT-6 Astra but cheaper and faster. Today they're launching GPT-6.1 Sol. 10:21 "Near-Astra level intelligence at a fifth of the price". 10:22 6.1 Sol is launching by today. 10:22 Also today: Ultrafast. 8x faster - up to 300 tokens/second. Available in the API, ChatGPT, and Codex. 6x the price of standard - "you know what, it's worth it" says Sam. 10:22 Ultrafast is available for Astra 6 today, and Sol 6.1 soon. 10:23 New subscription plan: Pro 500. This gives you access to Ultrafast, and 25x the usage of Plus. They're also putting their $200/month plan back on sale for new subscribers today. 10:24 Also today: previewing a new Decisions API. Lets the model respond "in a fraction of a second". It works by giving the Luna model "a predefined set of options to choose from". Sounds like their response to Jev, which came out of stealth less than two weeks ago! 10:25 Sam is now talking about Research acceleration: The view inside OpenAI. He brings up Tejal Patwardhan to talk about how they're using their own models to accelerate their research. 10:26 Tejal is talking about Astra's abilities at Computer Use. "Our models helped optimize the harness we use for Computer Use". They accelerated the harness, getting "a 2x latency win that we've shipped to all of you". 10:27 "Our models are much less likely to make a mistake while navigating the desktop and the browser" - which "should really matter for all your Dots". 10:28 10:29 Sam is back. Now talking about "supporting developers" - giving developers access to the same foundations they have at OpenAI. This starts with the open source Codex harness. Codex is also now "fully in the cloud". I had a bad experience with Codex in the cloud just two hours ago, so hopefully this new launch will make that a whole lot better. 10:30 Today launching "Codex Security Cloud", with "Daybreak Blue access" - scheduled scans, automatic de-duplication. Also launched today. 10:31 There's a (new?) Agents API, now with Computer Use. 10:31 (My eyes glazed over a bit at the AWS partnership section, but it only lasted a few seconds.) 10:32 Sam is dashing through a section about enterprise privacy features. 10:33 Sam is boasting about the "most performant and reliable API" available today. Feels like a jab at Claude, especially given they had an outage just this morning. 10:33 Romain Huet just made a fun entrance, with a live demo as he walked into the venue (with camera footage on screen.) 10:34 Looks like he's going to show off some 3D modeling with Ultrafast, in a live demo. The voice mode is not collaborating! He's going to have to type instead. 10:35 10:36 This is a good demo. He's typing commands like "put the livestream on the big screen" and a moment later the video appears on the big screen in the 3D model of the venue. 10:38 Romain is live coding an app to distribute free tickets to random attendees, using Ultrafast. 10:39 (This fits a pattern - in previous DevDays Romain has frequently run live demos that interact with the audience in interesting ways.) 10:39 Now we have an Astra Computer Use demo, where Astra figures out how to play a new (vibe coded) game. 10:40 10:41 ... and a demo showing Codex Remote building an app for the iPhone Duo, showing the UI from the simulator in the Codex UI. 10:42 Now Romain is switching to Codex Cloud, with "rewrite the entire backend in Rust". 10:44 10:46 Sam is back. 1.2B people use ChatGPT every week. "We've tried this before with variable results", but they're trying this again. First up: sign in with ChatGPT, which lets people sign into your app and use the tokens they are paying for already. I've wanted this one for years! 10:46 Also: Plugin extensions - plugins that are "entire applications" that feel native to ChatGPT (and Codex). 10:47 Here's an sample ChatGPT plugin from Adobe. 10:48 You can also build ChatGPT Sites and share them with specific other people. (I admit I thought they had that feature already.) 10:49 And they're launching the OpenAI Marketplace today, with these partners. 10:49 Finishing with a feel-good bit profiling some people who are building on OpenAI's platform. There's a video. 10:51 Keynote over. On the OpenAI blog: GPT-6.1 Sol, Introducing dots (I guess they're going with lowercase "dots" for that product name), and a DevDay 2026 Recap post. 10:52 And they're giving every attendee one of these. And a banked reset too. 10:53 They pressed the button live in the room. The reset affects everyone in the world, not just the DevDay attendees. 11:32 Well this is disappointing. I tried the create your dot link from their dots announcement and it told me to switch to a desktop! 12:47 I'm now in the ChatGPT Sites session. Jon Abrams initially prototyped this tool because he was frustrated at how hard it was to ship internal tools (I’ve felt that pain at many previous employers). It launched earlier this year and is already hosting 8m sites, and 70% of OpenAI employees are making their own sites. 12:47 Katia Gil Guzman demonstrates a spreadsheet of DevDay launches, and shows how to turn that into a Site. "Can you turn this sheet into a Launch Radar app in a new folder and publish it as a Site?" 12:48 12:49 You can also tell Codex to keep an eye on e.g. a shared sheet and continually update the site with new details. 12:50 Sites get a SQLite database! They're launching scheduled tasks for Sites today. 12:51 They also have "Sign in with ChatGPT" support. Sites default to private. 12:52 Launching today is Plugins in Sites, which will allow a Site to display data that is personalized for the visiting user imported from their plugins. I recently noticed that Claude Artifacts can access MCPs, which looks like the same shape of feature. 12:53 Here's the Radar Launch app built as a live demo in the session. 12:54 You can add other people as "editors", which allows them to publish updates to the Site themselves. 13:32 Now a session by Kyle Brown on Ian Webster on Codex Security. 13:33 At OpenAI they had a security sprint a couple of months ago involving a quarter of their product engineers, and they fixed 53 critical findings on the first day. 13:34 Today they're launching a major upgrade to their Codex Security Cloud product, integrating lessons learned from their internal security sprint. 13:35 13:37 They build a security knowledge base which includes architecture details and things that might not be visible in source code. They also now use SECURITY.md files, allowing product owners to define their own threat models and secure guidelines. 13:38 Running a scan using Codex Security. 13:39 The scanner keeps on looping until it can find no more issues. 13:40 Deduplication is now available as a workflow in the CLI. 13:41 In their internal sprint 36% of the discoveries were duplicates. Eliminating these saved a lot of developer time. 13:42 They put a lot of work into figuring out who owned what - a surprisingly hard problem in a company growing at OpenAI's rate. 13:43 Over time they got to the point where the system could generate patches. This was more of a "dial you turn up" as you get more comfortable with the quality of the results. 13:45 Now the codex-security patch command can generate patches and open PR. They only had a 1% rollback rate, thanks to a verify-fix command, which you can think of as an adversarial agent against the fix. 13:45 13:48 Here's a version of OpenAI's own internal burndown chart of their security vulnerabilities, showing the impact of their security sprint. 13:49 Codex Security Cloud lets you run continuous security. It's in the Codex plugins marketplace, and uses the Daybreak model that specializes in security. 13:50 It runs a scan, lets you inspect the vulnerabilities, and can generate patches and open PRs. It should be generally available today.

OpenAI's GPT-6.1 Sol Matches Flagship Performance at One-Fifth the Cost

OpenAI’s mid-tier coding model is being sold as almost flagship-smart at a fraction of the bill. GPT-6.1 Sol lists at $2 input and $10 output per million tokens, with cached input at $0.10. It matches Astra on DeepSWE coding tasks at about one-fifth the cost per task and comes within 2.1 points on OSWorld 2.0 computer use at about one-seventh the cost. It is live in ChatGPT Work, Codex, and the API as gpt-6.1-sol.

Notes
  • Positioning: upgrade to GPT-6 Sol; Astra flagship, Sol mid-tier, Luna lowest-cost.
  • API: $2 / M input, $10 / M output, $0.10 / M cached input (95% below standard input; 50% below prior Sol cached).
  • Benchmarks cited: matches Astra on DeepSWE v1.1 at ~20% cost/task; within 2.1 points of Astra on OSWorld 2.0 at ~1/7 cost; factual error rate 11.4%→7.7% at low effort vs GPT-6 Sol.
  • Availability: ChatGPT Work, Codex, API gpt-6.1-sol; Ultrafast variant coming.
  • Cache note: savings depend on hit rates; long agents resending system/repo/tool context are natural fit.

- OpenAI released GPT-6.1 Sol, a mid-tier upgrade approaching GPT-6 Astra quality at one-fifth the price. - API pricing: $2 input, $10 output, and $0.10 cached input per million tokens. - Matches Astra on DeepSWE v1.1 coding tasks at roughly 20% of the cost per task. - Comes within 2.1 points of Astra on OSWorld 2.0 computer-use benchmark at one-seventh the cost. - Factual error rate drops from 11.4% to 7.7% at low reasoning effort versus GPT-6 Sol. - Available now in ChatGPT Work, Codex, and the API as gpt-6.1-sol ; Ultrafast variant coming. GPT-6.1 Sol Brings Near-Astra Performance to the Mid-Tier OpenAI has released GPT-6.1 Sol, an upgrade to GPT-6 Sol for agentic coding, computer use, document analysis, and professional workflows. The company says it approaches GPT-6 Astra on several evaluations while charging substantially less per task. Within OpenAI’s three-tier GPT-6 lineup, Astra remains the flagship, Sol occupies the mid-tier, and Luna provides the lowest-cost option. GPT-6.1 Sol keeps standard input at $2 per million tokens and output at $10 per million. Cached input falls to $0.10 per million tokens, 95% below standard input pricing and 50% below GPT-6 Sol’s cached rate. | GPT-6.1 Sol API pricing | | | |---|---|---| | Token type | Price per million | Pricing context | |---|---|---| | Standard input | $2.00 | Applies to uncached prompt tokens | | Cached input | $0.10 | 95% below standard input | | Output | $10.00 | Applies to generated tokens | Cached Context Changes the Math Cached pricing applies to input tokens the API recognizes as reusable from earlier requests. At the listed rates, 10 million cached tokens cost $1, compared with $20 for the same volume of standard input. Actual savings depend on cache eligibility and hit rates because uncached input and generated output retain their standard prices. Long-running agents often resend system instructions, repository context, tool definitions, or large documents across multiple calls. Those repeated prefixes make coding agents and document pipelines natural candidates for the lower cached rate. OpenAI’s repeated comparisons with Anthropic’s Opus 5.5 also place Sol in direct competition for document analysis and business automation workloads. Near-Astra Scores at Lower Task Costs OpenAI cites results from several external benchmarks to support its near-Astra positioning. Reasoning effort controls how much inference-time work the model performs, with higher settings generally consuming more tokens. The reported cost-per-task figures combine each run’s token usage with the applicable API rates, so production costs will vary by workload. - Agentic coding: On DeepSWE v1.1, which tests software-engineering work in real codebases, GPT-6.1 Sol matches GPT-6 Astra at about one-fifth of the cost per task. It also exceeds GPT-6 Sol’s best score by 6.4 percentage points at a lower reasoning setting and cost. - Document question answering: On GDP.pdf, which covers complex finance, healthcare, and legal documents, GPT-6.1 Sol scores above the tested Opus 5.5 configuration with fallbacks enabled. It costs less than half as much per task across the evaluated reasoning settings. - Business automation: On AutomationBench, GPT-6.1 Sol scores 2.2 percentage points above Opus 5.5 at medium reasoning effort while costing about one-third as much. - Computer use: On the OSWorld 2.0 offline set, GPT-6.1 Sol comes within 2.1 percentage points of Astra at maximum reasoning effort and costs about one-seventh as much per task. - Scientific research: At maximum effort, GPT-6.1 Sol averages $5.47 per task, compared with $23.21 for Opus 5.5 and $23.80 for Astra. Astra retains the highest score on this evaluation at 68.1%. On OpenAI’s adversarial factuality set, GPT-6.1 Sol shows its largest gain over GPT-6 Sol at low reasoning effort. The share of responses containing a factual error falls from 11.4% to 7.7%, a relative reduction of about 32%. The dataset uses conversations in which users flagged an earlier model’s mistake, so its absolute error rates are higher than those expected across typical traffic. Tool Failures Get Clearer Handling OpenAI also reports lower failure rates for disclosing unavailable tools, following explicit restrictions, and avoiding unauthorized outcomes during agentic tasks. The broken-search evaluation checks whether the model tells the user that search failed. According to the system card addendum, GPT-6.1 Sol fails to disclose the problem in 2.1% of cases, compared with 4.9% for GPT-6 Sol and 1.5% for Astra. Rollout, Model ID, and Migration Tests OpenAI says the launch rollout covers paid ChatGPT plans, Codex, and the API. Availability differs by product surface: | Surface | Availability | Details | |---|---|---| | OpenAI API | Available | Use gpt-6.1-sol | | ChatGPT Work and Codex | Rolling out | Plus, Pro, Business, Enterprise, and Edu plans | | Chat | Not yet available | No release date provided | | Codex Ultrafast | Coming after launch | Up to eight times faster token generation | A representative migration test can establish whether Sol’s lower price offsets any quality difference for a specific production workload. Teams moving from Astra can evaluate: - Task completion rates against fixed acceptance criteria. - Total token cost, including cache hit rates and generated output. - Median and tail latency at the required reasoning settings. - The share of tasks that still require an Astra fallback. - Tool-use failures, permission violations, and unsupported claims. The reported results make GPT-6.1 Sol a candidate default for coding agents, document pipelines, and desktop automation. Astra retains an advantage on the cited scientific-research evaluation and may remain appropriate where measured quality gains cover its higher cost. Cache-heavy workloads receive the largest direct savings when repeated prompt content consistently qualifies for cached pricing.

Supersonic Labs Ships Julia-1, a Tiny 144M Router That Classifies Without Retraining

A tiny open model can pick from a short list of answers without you retraining it when the labels change. Supersonic Labs released Julia-1, 144.3 million parameters, Apache 2.0, on mmBERT-small. You send a state, a question, and two to twenty options. Three modes: choice, ordered score, and Boolean (noul). Reported scores: 73.15% typed decisions, 94% AG News, 86% Emotion, 71.5% MASSIVE across 52 locales. A Banking77 pilot is 64/100 versus 87/100 for a reference. An ONNX/WebGPU build is 75 ms in-browser with 100/100 parity to PyTorch. Training code stays private. The rest is paywalled.

Notes
  • Julia-1 (Supersonic Labs): 144.3M parameters, Apache 2.0. Fine-tuned from JHU CLSP mmBERT-small (multilingual ModernBERT encoder). Input: state + question + 2–20 options. Three modes: choice (winning option ID + probabilities), score (rubric index), noul (Boolean, optional descriptions). Labels travel with the request — change classes without retraining or a new head. First public Julia-family model; training pipeline stays private; weights + inference code released. Laptop CPU or a separate WebGPU/ONNX export.
  • Scores in the free preview: 73.15% typed decisions; 94% AG News; 86% Emotion; 71.5% MASSIVE across 52 locales. Weak on long label lists: 64/100 Banking77 pilot vs 87/100 reference. ONNX/WebGPU: 75 ms per decision in-browser, 100/100 parity to PyTorch.
  • Candidate meanings are part of each request, so an app can swap the label set at inference time. The encoder turns text into vectors; Supersonic added a classification layer that scores the supplied options in order.
  • Aimed at routing and classification on a laptop CPU, not open-ended generation. The WebGPU export is a separate build from the PyTorch weights.
  • Paywall after the mode table. Do not invent remaining benches, serving QPS, or a training-set size.

Jev-Omni Scores Decisions Across Text, Images, Audio, and Video in Milliseconds

An open multimodal classifier scores fixed answer choices across text, images, audio, and video instead of generating free prose. Jev-Omni is a 12B Apache-2.0 model fine-tuned from Gemma 4 12B IT; reported DecisionBench Medium accuracy is 87.57% with warm H200 text latency around 83 ms. Best with twenty or fewer options and needs a CUDA GPU for comfortable inference. Independent of TypeSafe’s Jev product.

- Jev-Omni is a 12B multimodal decision classifier built on Gemma 4 12B IT, Apache-2.0 licensed. - Handles text, image, audio and video in one model, returning calibrated probabilities over supplied options. - Scores 87.57% on DecisionBench Medium, 63.10% MMAU, 53.10% MVBench; ECE of 0.0400. - Warm H200 latency: 83ms text, 26ms image, 31ms audio, 504ms 16-frame video. - Best at 20 or fewer options; needs ~50GB FP32, inference in BF16 on CUDA GPU. - Try it free on the hosted Space; independent of TypeSafe AI's Jev. Jev-Omni scores fixed choices across four modalities Jev-Omni is a 12-billion-parameter open-weight classifier that accepts text, images, audio, or video and assigns a probability to each supplied answer. A request contains a state, meaning the context being evaluated, along with a question and candidate options. The fixed output contract gives applications structured decisions without parsing generated prose. The model was fine-tuned from Gemma 4 12B IT on 30,000 questions. Its author claims it is the first downloadable checkpoint to support all four modalities through one decision interface, a combination that many open-weight alternatives lack. The repository lists an Apache-2.0 license; adopters should also review the terms attached to the upstream Gemma components downloaded by the loader. Fixed choices, usable probabilities Generative multimodal models emit token sequences that structured pipelines must validate and parse. Jev-Omni directly scores the options supplied with each question, reducing the need for regular expressions, constrained decoding, or a separate judge model. The typed-decision interface supports yes/no, multiple-choice, and score questions. On the medium split of DecisionBench, the model card reports an expected calibration error of 0.0400 across 10 confidence bins. Expected calibration error measures the weighted gap between predicted confidence and observed accuracy, so 0.0400 represents an average gap of about four percentage points on that test split. Calibration can change with new data and deployment conditions. This story is for Pro members You've reached the end of the free preview.

Gartner Predicts 70% of Enterprises Will Abandon Agentic AI Built by Vendor Forward ...

An analyst shop thinks most companies will walk away from agent products that vendors staffed with on-site engineers. Gartner predicts 70% of enterprises will abandon agentic AI built by vendor forward-deployed engineering by 2028. The stored line blames soaring costs and teams that cannot evolve those engineers on their own, and it points to a “three-phase solution.” The phases are not in the excerpt.

😺 Meta wants to own your AI front door

The next fight is over the assistant that sits between you and every click, shop, and payment. Meta’s Muse, Manus 2.0 plus Cue, and Instinct (a $1B Series C at a $10B valuation, a month after $350M at $2.5B) all shipped that layer. Muse gets a VM and browser; Manus keeps cloud computers running after you leave; Cue gets a phone, email, wallet, and computer. A panel says liability law may decide whether the agent represents you or the vendor. Same edition: OpenAI reportedly pulled GPT-6.1 Astra before DevDay; AMD’s World Labs deal; an Anthropic IPO leak. Florida asked a court to restrict new OpenAI models.

Notes
  • The Neuron (Grant Harvey). More or Less panel: who pays when agents act is “the #1 open question of the agent economy.” Dave Morin: does the agent represent you or the company that built it?

😺 Meta wants to own your AI front door PLUS: Agents now get phones, wallets, computers, and permission to transact. Welcome, humans. Okay, so I heard an interesting prediction this weekend: who gets blamed when AI agents do something bad is the #1 open question of the agent economy. On More or Less, the group says AI safety gets weirder when we consider our new “agent ecology”: potentially billions of agents researching, negotiating, buying things, writing software, and dealing with other agents on our behalf. When this happens, alignment gets messy. Dave Morin’s question: does your agent actually represent you, or the company that built it? Sam Lessin thinks liability law may decide it. - If the AI company is liable, he predicts it will optimize for self-protection. - If users are liable, incentives shift toward user control. - Across thousands of services, whoever bears responsibility could shape the ecosystem. Now, that’s a prediction, not the current legal framework. The point: companies will ship agents before society decides who pays when… - Hacks something… - Makes a bad purchase… - Breaks another service… - Or causes damage. The panel says frontier labs could face losses far beyond normal software failures, what Sam calls “infinite liability,” unless governments absorb some risk. So we may spend the next few years obsessing over agent benchmarks, only to discover that one of the most important AI alignment mechanisms is… tort law. Here’s what else happened in AI today: - 😺 Meta, Manus and Instinct raced for your main agent. - 📰 Florida sought emergency restrictions on OpenAI models. - 📰 Researchers warned AI could accelerate AI research. - 🍪 NVIDIA moved agent safety below the model. - 🎓 Jev routed cheap decisions away from big models. ICYMI: our recent Deep Dive covers an AI agent that created fake identities to pressure a real person, plus the common company risk: ordinary tools with access nobody is watching. Special shout out to Harmonic Security for sponsoring this one! 😺 Meta, Manus and Instinct Are Racing to Become Your Main AI Agent… Yesterday, there was a flood of agent announcements that looked like a land grab for the layer between you and the internet, dressed up as adorable little assistants! Meta finally has its Muse; Manus launched Manus 2.0 and spun-up Cue; and viral invite-only agent Instinct became a Silicon Valley darling with a $1B Series C at a $10B valuation, one month after $350M at $2.5B. What’s going on here? Different layers, same direction: AI is moving from something you open to something that represents you* (well, per above does it??), with a computer, memory, credentials, permissions, and autonomy. Examples: - Muse gets a secure VM and browser. - Manus 2.0 gets persistent cloud computers and automations that keep running after you leave. - Cue gets a phone number, email, wallet, and computer. The cuteness masks the business model. Ben Thompson’s Stratechery frames these agents as the next, most ultimate aggregator: Publishing abundance let Google and Facebook aggregate discovery; action abundance lets agents aggregate where you shop, book, compare, negotiate, build, research, and pay. So what does this mean? Whoever owns the interface sees your intent first, and aggregates everything else. Want a Chicago flight under $500? Your agent picks the service, tradeoffs, and supplier. The airline supplies the seat; the agent owns the relationship end to end. Dave Morin of More or Less sees it differently. He says the future will be more “polyagentmorous”: every app becomes an agent, with “no one agent to rule them all.” What connects them? “THE INTERNET.” Or should we say… Metaverse? The new Prime Agent previews that architecture: persistent sub-agents that message, preserve memory, and update their setup. Using Claude Cowork or ChatGPT Codex (or other agents) gets you used to it, too: calling up subagents to do work for you from your main agent chat. This pattern of work is used more for coding and research today, but the model is the same: your main agent boo delegates to your side piece agents. They’re just there to get the job done, you don’t care about maintaining the longevity of the relationship, ya know? How’s that for polyagentmory, Dave! Why this matters: If you run a business, becoming everyone’s main agent means fighting Meta, Microsoft, OpenAI, Anthropic, Google, Manus, Instinct, and the open agent ecosystem. You don’t want that smoke, bro. Better: make your goods and services easy for somebody else’s agent to use. - Expose machine-readable inventory, availability, pricing, and policies. - Offer reliable APIs, MCP connectors, or structured actions. - Make authentication, permissions, purchases, and refunds agent-friendly. - Be the supplier the aggregator picks. Computer-use agents can click almost any website, so “we don’t have an API” isn’t much of a moat. It makes you slower and error-prone. Muse’s momentum matters because Meta combines distribution, a dedicated computer, payments, connectors, context, and an enterprise extension… with Meta’s instant distribution to 3.6B daily active users behind it. The internet was built around getting humans to click your website. The next one may be built around getting an agent to pick you.

The new chat keeps everything before it; the original stays untouched. - Hover over the message. - Click More actions (⋯), then Branch in new chat. - Try the alternate plan, rewrite, or debugging path.

As Victor Dibia writes, Jev skips prose: it scores predefined choices and returns the winner with confidence. Think “sales / support / billing,” “yes / no,” or “cheap model / expensive model.” That changes the workflow: use expensive generative models only when generation is required. - List recurring decisions with a small answer set. - Route them through a decision model or classifier. - Escalate uncertain or open-ended cases to your frontier model. A useful rule: if you can write every valid answer on a sticky note, you probably don’t need a giant model composing prose to pick one.

Getting the Source Right, Not Just the Fact: Source-Aware Verification for MCP Agents

A fact can be true in the evidence pool and still wrong if the agent attributes it to the wrong tool or document. ProvenanceGuard is a post-generation check for MCP agents that keeps source IDs attached while it splits claims, scores support, and compares attributed versus actual sources. On a medical-agent test set it blocked 138 of 139 claims experts said should fail, with reject/block F1 0.802 versus lower source-blind baselines. Separating similar sources remains hard (about 50% exact source ID in a harder test).

Notes
  • Problem named: cross-source conflation — claim true somewhere but attributed to wrong source; source-blind faithfulness can pass it.
  • ProvenanceGuard: post-generation layer on black-box MCP agents; preserves source identity through claim decomposition, routing, support scoring, attribution check, allow/block; optional RARR-style repair + re-verify.
  • Eval setup (paper): local MiniLM + DeBERTa NLI + local LM for claim split; 281 medical-agent traces; experts labeled 361 claims from 40 held-out answers.
  • Results: experts said 139 should not pass → system caught 138 (one miss); also held 67 supported claims for review (conservative). Right source ~86% when identifiable. Reject/block F1 0.802 vs MiniCheck 0.783, RAGAS 0.758, AlignScore 0.662, SummaC-ZS 0.436; only ProvenanceGuard emits claim-to-source IDs.
  • Harder multi-similar-source test: block F1 0.846 but exact source ID only 50.3%.
  • Paper: ProvenanceGuard: Source-Aware Factuality Verification for MCP-Based LLM Agents (HF / arXiv).
Full text · 8,290 chars
Our latest paper, ProvenanceGuard: Source-Aware Factuality Verification for MCP-Based LLM Agents (read it on Hugging Face, or on arXiv in the meantime), targets that gap. The failure mode we care about is one we call cross-source conflation: a claim that is true somewhere in the evidence, but attributed to the wrong source. A source-blind verifier may pass it, because the fact does exist in the pool. A source-aware verifier should not. Consider a customer support agent that answers, "According to the account record, this plan includes a 30-day refund window." The refund window may be perfectly real, but stated in a policy document, not in the account record the answer points to. Pool the two together and the claim looks supported. Keep them separate and the attribution is wrong, and in a data-sensitive setting a wrong attribution can be as damaging as a wrong fact. The same pattern shows up in a clinical agent, where a patient-specific medication detail taken from a patient-history tool becomes misleading the moment the answer presents it as a finding from the medical literature. A claim can be supported by one MCP source while the answer attributes it to another. Source-blind scoring sees support in the pooled evidence and passes it; ProvenanceGuard separately checks whether the supporting source matches the one the answer states or implies. Source: paper Figure 1. This is why faithfulness scores, useful as they are, are not enough for MCP agents. An answer carries provenance, sometimes explicitly ("according to the account record") and sometimes implicitly. ProvenanceGuard keeps that connection between claim and source available for inspection. ProvenanceGuard is a post-generation verification layer that sits on top of a black-box MCP agent. It runs after an agent produces an answer, and never collapses the evidence into one anonymous context. Instead it carries the source identity all the way through the pipeline. It reads the captured MCP trace, including the tool outputs and their source IDs, without retraining the agent. Then it does five things in sequence: it breaks the answer into specific claims, finds the source most relevant to each one, checks whether that source actually supports it, compares the source with the one the answer names or implies, and finally emits both a per-claim source verdict and a global, answer-level allow or block decision. The verification flow. Source identity is preserved through decomposition, routing, support scoring, attribution checking, and repair, rather than being pooled. Blocked answers can go through RARR-style repair and be re-verified. Source: paper Figure 2. A few of the design choices are worth calling out. For the experiments in our paper, we used local models so the captured traces could be processed in a controlled, offline setup: MiniLM helps find the relevant source, a DeBERTa NLI verifier model checks whether that source supports the claim, and a local language model helps break answers into claims. The verifier also checks literal values closely: a number, date, or identifier absent from the source cannot pass merely because the sentence sounds plausible. A calibrated decision step combines these signals. If an answer is blocked, a RARR-style repair step can try a source-grounded revision or a safe fallback, which the verifier then checks again. Those named models are the setup we evaluated, not a requirement of ProvenanceGuard. The same claim, source, and decision steps can be adapted to hosted models where a team prefers cloud services; a new setup would need its own testing and calibration. Our reported results come from the local configuration. Its conservative decision policy suits data-sensitive review, where getting the source right matters more than producing the fastest possible answer. We tested ProvenanceGuard on answers from a medical agent that had used patient records, research articles, and other tools. This gave us 281 real traces to study. Medicine is a useful test because a fact from a patient's record and a fact from general research cannot be treated as the same source. The method can also be used in other fields when an agent keeps a record of its tool outputs and source IDs. For the main test, human experts checked 361 claims from 40 answers set aside from the data used to develop the system. The most direct result is this: experts said 139 claims should not pass, and ProvenanceGuard caught 138 of them. It let one through. It also held 67 claims that the experts considered supported, sending them for review or repair. This reflects the cautious setting we tested: it favors a second look at some supported claims over letting unsupported ones through. For claims with an identifiable source, it also picked the right source about 86% of the time in this test. We ran four other support checkers on the same claims. ProvenanceGuard scored highest on the paper's measure of how well a system catches claims that should be blocked while avoiding unnecessary blocks. The other checkers in this comparison did not tell us which tool output supported each claim. ProvenanceGuard records that connection, so a reviewer can see the source checked for each claim and the decision it produced. | Verifier | Reject/block F1 | Emits claim-to-source ID | |---|---|---| | ProvenanceGuard (ours) | 0.802 | Yes | | MiniCheck | 0.783 | No | | RAGAS Faithfulness | 0.758 | No | | AlignScore | 0.662 | No | | SummaC-ZS | 0.436 | No | Binary support metrics on the same held-out claim packet. ProvenanceGuard matches or beats the source-blind baselines on blocking while also producing per-claim source verdicts. Source: paper abstract and Table III. In a separate, harder test with several similar sources, ProvenanceGuard scored 0.846 F1 for deciding which claims to block, but identified the exact source correctly in 50.3% of claims. Telling similar sources apart remains an important area for improvement. We also ran a controlled test focused on wrong attribution: we changed the named source in 50 cases while leaving the supporting evidence intact. ProvenanceGuard caught all 50 swaps. This shows it can detect a clear source error, while the harder test shows the challenge of choosing among many plausible sources. Blocking is only useful if there is something to do with a blocked answer. Wired to the RARR-style repair loop, the full-trace run resolved all 173 blocked answers, though 144 of them ended in fallback text rather than a substantive rewrite, which is the system choosing to avoid an unverifiable answer rather than manufacture one. On reconstructed multi-source test traces, a fresh repair run resolved all 59 initially blocked answers with only two terminal fallbacks. As an offline gate the overhead is modest, roughly half a second per answer on the reported local configuration, with the NLI and routing calls themselves in the tens of milliseconds. As agents move from single-passage RAG to multi-tool MCP setups, the question of which source a fact actually came from stops being a footnote and becomes part of what factuality means. ProvenanceGuard makes that source connection visible claim by claim. For Multiverse Computing, that means a way to check existing agents while keeping sensitive traces in a controlled environment when needed. The medical study is one use case; the same approach can be adapted wherever an agent's trace preserves its tools and sources. That adaptation is already visible in NVIDIA NVFlow, which merged an optional grounding-verification stage for its finance agent. It checks completed answers against the SEC excerpts the agent retrieved and saves separate decisions without changing the original rollout or training data. The NVFlow contribution uses ProvenanceGuard's source-aware verification approach; the repair loop discussed above belongs to the broader research system. ProvenanceGuard was also presented as a poster at the Agentic AI Summit 2026 at UC Berkeley.

NVIDIA Kumo Tabular, part of the NVIDIA Kumo Structured model collection, is an open foundation model for tabular data now available on Hugging Face. Given a table of labeled rows, it predicts the labels of new rows in a single forward pass, with no training, no tuning, and no feature engineering, for both classification and regression. It was pretrained only on artificial data, comes in three sizes (28M to 215M parameters), runs through our open-source library, and is released under the OpenMDW-1.1 license for commercial use. It ranks first on the four benchmarks TabArena, BeyondArena, TALENT and ScoringBench. - Model Code: https://github.com/NVIDIA/structured-data-models - Model Weights: https://huggingface.co/nvidia/Kumo-Tabular Tabular data is the backbone of enterprise machine learning. Customer records, transactions, sensor logs, claims, and orders all live in tables, and predicting churn, default, demand, or price from them is among the most common machine learning tasks in industry. For two decades, this work has been done with gradient-boosted trees, and it has worked well. But the lifecycle around those models has barely changed. Every new question means collecting labels, engineering features, searching hyperparameters, validating, and deploying a model that knows nothing about tables in general and learns each task from scratch. Large Language Models showed a different way of working with new tasks. Given a few examples in the prompt, a pretrained model solves the task without updating a single weight. This is in-context learning, and it applies to tables just as well as to text: a model pretrained on millions of tables can read a labeled table as its context and predict the labels of new rows directly. Today, we are releasing NVIDIA Kumo Tabular (GitHub, HuggingFace), an open foundation model for tabular classification and regression. Given a table with labeled rows and the rows you want predictions for, Kumo Tabular returns class probabilities or numeric predictions in a single forward pass. Kumo Tabular is a Transformer built around the structure of a table, utilizing column, row and in-context attention as introduced in TabICL and TabPFN. To predict a label it has to do three things: (1) understand what each value means within its column, (2) understand how the columns of a row interact, and (3) relate the context rows with existing labels to the query rows with unknown labels. Kumo Tabular achieves this as follows: Cell Embedding: A group of cells becomes a token. Numerical and categorical values pass through Fourier features, sines and cosines of learned frequencies, with separate weights for each type. Missing values need no imputation and are treated specially. Finally, every token in the context receives a label embedding. Row Embedding: We then turn each row into an embedding by alternating two kinds of attention multiple times. Column attention looks down a single column and learns what a value means in the distribution of its column, e.g., whether a 42 is typical or extreme, via induced self-attention. Its cost therefore grows linearly with the number of rows. Row attention looks across the tokens of a single row and learns how features interact, with rotary positions to tell columns apart. Four learnable [CLS] tokens join each row and act as the final readout of a row. After this row compression, the cost of the final stage no longer depends on the number of columns. In-context Learning: A final Transformer operates on the row embeddings. Context rows attend to each other, while query rows attend to context rows only. Each prediction therefore depends only on the context and on the row itself, not on which other rows are scored alongside it. Because the context never looks at the queries, its keys and values are computed once and can be reused for follow-up predictions. Query rows utilize Test-GQA, which shrinks the cache that every prediction reads. A head turns each query row into class probabilities for classification and 999 quantiles for regression, from which a point prediction and an uncertainty estimate follow. Length-aware Attention Temperature: Softmax attention spreads out as the number of keys grows. Attention that is sharp over a few hundred rows can dissolve over tens of thousands, which is exactly the situation when a table at inference is much larger than a typical training table. Kumo Tabular therefore scales every query by a temperature that grows with the logarithm of the number of keys, with a coefficient learned separately for each attention head. The result is attention that stays sharp as tables grow longer or wider. Kumo Tabular is pretrained entirely on artificial tables. Each training table is sampled from a Structural Causal Model (SCM) in the six steps shown below: We first draw a configuration for the whole table, from its size and task to its mechanisms and missingness. A random causal graph then links hidden variables, evaluated from root to leaf via randomly drawn functions at every node (e.g., linear maps, small neural networks, trees or Gaussian processes). Some nodes become numerical or categorical columns, one becomes the target, and the rest stay hidden, like the unmeasured causes behind real data. Post-processing correlates groups of columns, clips outliers, and injects missing values, and a quick tree-ensemble check discards any table without a learnable signal. Because the generator is a procedural sampler rather than a trained model, it produces an endless supply of tables, each with a new graph and new mechanisms. Real-world tables are messy, so we built more of their imperfections into the generator. Values go missing in several patterns, some features are coarsened so that duplicate rows may disagree on their label, some categorical columns carry many levels, and regression targets can be heavy-tailed. A model that has seen millions of such tables learns to handle these imperfections without any cleanup. On every artificial table, the model sees most of the rows with their labels as context and learns to predict the labels of the remaining rows, with a cross-entropy loss for classification and a quantile loss for regression. Classification and regression are trained as separate models. Similarly to TabICLv2, training runs in three stages. The first and longest stage uses tables of 1,024 rows and up to 100 columns and teaches the model what tables look like. The second stage varies the context from 400 to 10,240 rows, and the third extends it to 60,000 rows, still with up to 100 columns. In total, Kumo Tabular-Small/Medium/Large saw about 35/71/137 million artificial tables. Our training recipe and artificial data generators will be released soon. We ran all three Kumo Tabular sizes with default settings against the full TabArena leaderboard, spanning tuned gradient-boosted trees, AutoGluon, and the latest tabular foundation models. Kumo Tabular ranks first overall with an ELO of 1950 while running 17 faster than LimiX-2 under a uniform single RTX 6000 Pro evaluation setup. Across all three three model sizes, Kumo Tabular establishes a new state-of-the-art on the accuracy-efficiency Pareto front: We also evaluated Kumo Tabular on BeyondArena, TALENT and ScoringBench. On BeyondArena, Kumo Tabular reaches an ELO of 1418 with an Improvability score of 7.78%, placing first on the leaderboard. On TALENT, it achieves the top overall ranking across classification accuracy, classification log-loss, and regression RMSE, with average ranks of 6.67, 3.98, and 4.22. On ScoringBench, a benchmark for predictive distributions, Kumo Tabular-Large and Medium rank first and second on average rank. Kumo Tabular works on numerical and categorical columns only, while text, images, or timestamps can be turned into features via built-in pre-processing recipes. A single forward pass covers up to 10 classes, which the library extends to any number of classes with error-correcting output codes. Accuracy may degrade on tables far beyond the training ranges or when the query rows come from a different distribution than the context rows, so, as with any predictive model, validate accuracy and calibration on your own held-out data before deployment. Kumo Tabular runs via NVIDIA's newly released GPU-native library for structured-data-models. The library downloads the weights from the Hub on first use and provides the preprocessing, ensembling, and many-class handling used in our evaluations. The code below is all it takes to go from a pandas.DataFrame to a prediction: import sdm # structured-data-models # Tensorize tabular data: table = sdm.TableTensor.from_pandas(pd.load_csv(...), device="cuda") na_mask = table["target"].isnan() model = sdm.models.KumoTabular(device="cuda") pred = model( # In-context examples (features/targets): x_context=table[~na_mask].drop_columns("target"), y_context=table[~na_mask, "target"], # Prediction examples (features): x_query=table[na_mask].drop_column("target"), ) Kumo Tabular is released under the OpenMDW License Agreement, version 1.1. NVIDIA believes Trustworthy AI is a shared responsibility, and we have established policies and practices to enable development for a wide array of AI applications. When downloaded or used in accordance with our terms of service, developers should work with their supporting model team to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.

NVIDIA packages Qwen2.5-VL 7B for native FP4 inference on Blackwell NVIDIA has released a pre-quantized build of Alibaba’s Qwen2.5-VL-7B-Instruct for Blackwell GPUs. The model repository packages the vision-language model in NVIDIA’s NVFP4 format and targets deployment through TensorRT-LLM. Blackwell Tensor Cores can execute NVFP4 natively, giving the checkpoint a path to lower memory use and higher inference throughput than BF16 or FP8 builds. Those gains apply mainly to the language model’s quantized linear layers; the vision encoder and several supporting tensors remain at higher precision. NVFP4 squeezes weights into 16-value blocks NVFP4 stores each quantized value in an E2M1 layout: one sign bit, two exponent bits, and one mantissa bit. Because four bits alone provide limited range, the format adds two levels of scaling: - Each 16-value micro-block shares an FP8 E4M3 scale. - Each tensor also carries an FP32 scale. - The FP8 block scales raise average storage to about 4.5 bits per value, with negligible additional cost from the per-tensor scale. The storage ratio works out to roughly 3.6 times less than BF16 for quantized tensors. Blackwell also advertises twice the peak Tensor Core throughput for FP4 relative to FP8. End-to-end results depend on the vision encoder, KV-cache traffic, request batching, kernel availability, and the share of execution that remains at higher precision. The vision stack stays at higher precision NVIDIA produced the checkpoint from the Qwen base model with post-training quantization in Model Optimizer.

OpenAI's Codex Now Scans GitHub Repos Using Daybreak Blue Security AI

Codex can now scan whole GitHub repos with OpenAI’s defensive security models without a separate access request. Security Cloud uses Daybreak Blue by default for on-demand, scheduled, or post-commit scans, dedupes findings, and prepares fixes for review in the cloud. Blue maps to a gpt-5.6-sol snapshot with a 1,050,000-token window; offensive Daybreak Red still needs separate approval. Ships as a plugin for Pro, Business, Enterprise, and Edu.

- Codex Security Cloud upgrade now includes Daybreak Blue cyber-capable models by default, no separate application needed. - Scans entire GitHub repositories, monitors new commits, deduplicates findings, and prepares fixes for review. - Daybreak Blue is the defensive tier, mapping to gpt-5.6-sol with a 1,050,000-token context window. - Daybreak Red (offensive) still requires separate approval and is not included in this rollout. - Available as a plugin inside Codex desktop and web for Pro, Business, Enterprise, and Edu plans. - OpenAI recommends GPT-5.6 Sol with xhigh reasoning for scans; model picker still lets you choose. Codex Security Cloud adds Daybreak Blue to GitHub repository scans OpenAI is rolling out an upgraded Codex Security Cloud that includes access to its Daybreak Blue cybersecurity models. Eligible Codex users can connect GitHub repositories without submitting a separate Daybreak Blue application. Codex can scan repositories on demand, on a schedule, or after new commits. It investigates and deduplicates findings, proposes patches, runs relevant tests, and prepares changes for review in the cloud, so scans continue without an active desktop session. The service is available as a plugin in the Codex desktop and web apps. Daybreak Blue brings defensive models into Codex Daybreak is OpenAI’s cybersecurity model program. Its Blue tier covers defensive work such as vulnerability research and malware analysis. Daybreak Red supports offensive security tasks and retains a separate approval and provisioning process. Blue previously required identity verification and a dedicated access request. Codex Security Cloud now includes that model access for eligible workspaces, although OpenAI may still require workspace verification or Know Your Business checks. The gpt-daybreak-blue-latest alias currently points to the gpt-5.6-sol snapshot with a 1,050,000-token context window. Tokens are the pieces of text a model processes, and that large window lets it examine substantial amounts of code and surrounding repository context in one run. Teams that require reproducible audits should record the model version used because aliases ending in latest can change. Findings move from scan to pull request OpenAI’s product page describes a workflow that covers discovery and remediation. Codex analyzes code and recent changes for likely vulnerabilities, uses repository context to reduce false positives, and consolidates duplicate reports before presenting the results. For accepted findings, the service can generate focused patches, run relevant tests, and prepare reviewable changes with supporting evidence. Human approval remains part of the workflow, allowing teams to apply their existing branch protections and code-review requirements. GPT-Daybreak supplies the underlying security reasoning. Codex Security handles repository access, orchestration, deduplication, validation, patch preparation, and the review interface. That division turns a model response into a workflow engineering teams can inspect and govern. Scans can follow commits or schedules The plugin supports three scan triggers, each suited to a different part of the development cycle: - On demand: Run a repository-wide assessment before a release, audit, or major refactor. - On a schedule: Recheck active repositories as code and dependencies change. - On new commits: Review incoming changes for security regressions during development. The model picker inside the plugin controls which model performs a scan. OpenAI recommends GPT-5.6 Sol with the xhigh reasoning setting for security scans, even when Daybreak Blue access is enabled. Setup takes five steps OpenAI’s Trusted Access docs recommend starting with Daybreak Blue. Access to Blue does not grant access to Daybreak Red or GPT-Daybreak-Red. - Confirm that the workspace is eligible for Codex Security and Daybreak, completing business verification if requested. - Enable Daybreak Blue and confirm access to gpt-daybreak-blue-latest . - Connect the required GitHub repositories through the Codex Security plugin. - Select a scan model and configure on-demand, scheduled, or commit-triggered runs. - Review deduplicated findings, test evidence, and proposed pull requests before merging changes. Workspace administrators should review repository permissions, data controls, branch protections, and approval rules before enabling organization-wide scans. Generated patches should pass the same tests and human review as other code changes. Access comes through existing Codex plans | Category | Availability | |---|---| | Plans | Pro, Business, Enterprise, and Edu | | Interfaces | Codex desktop and web apps | | Repository host | GitHub | | Packaging | Included in Codex Security Cloud, with no separate SKU | Continuous review gains repository context Static application security testing tools often match code against rules and produce long alert lists. Codex Security adds model-based analysis across repository context, then groups related findings and proposes a concrete fix. That approach may be useful for authentication flaws, injection vulnerabilities, unsafe deserialization, and regressions introduced by pull requests. Security teams still need static analysis, dependency scanning, penetration testing, red-team exercises, and human review. Daybreak Blue’s safeguards also restrict assistance with exploit development. Codex Security Cloud adds a persistent defensive reviewer that can examine each change and return a tested patch for engineers to assess.

OpenAI's Codex CLI Rebuilds the Terminal to Run Parallel Coding Agents

The terminal coding agent now looks more like a control room for several jobs at once. Codex CLI gets a full-screen interface with a pinned prompt, on-demand history, and an /agents view to jump between parallel sessions. /fork clones a chat into a git worktree so competing changes stay separate. Voice in and out, collapsible diffs, and Mermaid/LaTeX rendering land in-terminal; update via npm `@openai/codex@latest`.

- Codex CLI gets a full-screen TUI with a pinned composer and unlimited scrollback history - /agents lists running tasks and lets you jump between parallel Codex sessions - /fork clones a conversation into a git worktree with separate checkout for branching work - /voice enables talking to Codex and hearing responses directly in the terminal - Adds /usage ,/theme , collapsible diffs, Mermaid and LaTeX rendering in-terminal - Update with npm install -g @openai/codex@latest ; see docs Codex CLI adds a full-screen workspace for parallel agents OpenAI has refreshed Codex CLI, its open-source coding agent for the terminal, with an interface built for long-running and concurrent work. The release pins prompt input to the bottom, loads older session history on demand, tracks parallel agents in one view, connects conversation forks to Git worktrees, and adds two-way voice. Developers who keep Codex open beside an editor now have a workspace for supervising several tasks from one terminal. The prompt stays put The full-screen terminal user interface separates the session transcript, composer, status information, hints, and keyboard shortcuts into dedicated regions. The composer remains fixed at the bottom while the transcript scrolls, allowing developers to inspect earlier output and enter the next prompt without jumping through the session. Older messages load as the user scrolls beyond the terminal’s normal scrollback limit. Long diffs and tool output can be collapsed, while Mermaid diagrams and LaTeX render inside the terminal. Themes are available through /theme. Parallel agents share one screen The new /agents view lists concurrent tasks, shows their progress, and lets the user switch between them without opening additional terminal windows. It gives subagent workflows a central place for monitoring runs, checking results, and redirecting work. Inside a Git repository, /fork now pairs a copy of the current conversation with a managed worktree. A worktree is a separate checkout that shares the repository’s underlying Git data, allowing each fork to edit files independently. Developers can test competing implementations while keeping their working directories and diffs separate. Earlier Codex CLI releases already supported conversation forks through /fork and the codex fork subcommand. Linking forks to managed worktrees extends that model to the filesystem. The separation reduces accidental overlap, although developers still need to review, merge, and resolve conflicts between successful branches. Voice joins the prompt loop The /voice command starts a spoken conversation with Codex, including speech input and audio responses. The release notes say voice conversations are enabled by default, with F8 as a toggle and /voice providing the settings picker. OpenAI also bundles the required audio runtimes for Linux and Windows, reducing platform setup. Voice is suited to high-level instructions, follow-up questions, and status checks, while the transcript and agent output remain available for precise inspection. A broader toolbox behind the interface - /usage displays activity and usage information within the session. - /theme switches among the new terminal themes. - Collapsible sections reduce the space consumed by large diffs and verbose tool output. - Inline Mermaid and LaTeX rendering presents diagrams and formulas without a separate viewer. - Dedicated status, hint, and shortcut regions keep controls visible during long runs. Built for long-running repository work The redesign builds on several existing Codex CLI capabilities: - AGENTS.md files provide repository-specific instructions and project context. - Configuration profiles preserve settings for different projects or workflows. - codex exec runs non-interactive tasks from scripts and automation. - The sandbox restricts command, file, and network access according to configured permissions and approval rules. These features fit developers who keep an agent attached to a repository, delegate several tasks, and review changes before committing them. One-off questions gain little from the additional interface, and teams adopting parallel agents need clear branch, test, and review practices. The richer interface also occupies more terminal space than the earlier chat-style loop. Upgrade in one command The update ships through the existing npm package. Install Codex CLI or upgrade a global installation with: npm install -g @openai/codex@latest Authentication supports a ChatGPT account or an API key. ChatGPT access follows the account’s plan and usage limits, while API-key sessions are charged to the associated API project under current pricing. The /usage command provides in-session visibility into activity. Codex CLI remains open source under the Apache 2.0 license. Its source code, issue tracker, and release history are available in the GitHub repository. The terminal becomes a control plane Combining agent monitoring, worktree-backed forks, reviewable output, and voice control makes the terminal a primary surface for coordinating coding agents. The design assumes that developers will run several tasks concurrently and move among planning, execution, and review within the same session. That model can increase throughput, but it also moves the bottleneck toward verification. Developers remain responsible for inspecting diffs, running tests, managing permissions, and deciding which branch should reach the codebase. The refreshed CLI makes parallel work easier to organize while keeping those decisions visible in the repository and terminal.

OpenAI's Decisions API Gives Developers a Constrained GPT-6 Luna Router

OpenAI shipped a constrained router API so apps can force the model to pick from a fixed answer list in a fraction of a second. The Decisions API runs on GPT-6 Luna and takes developer-defined options over text or image input. It is positioned as a fast structured-decision path alongside the bigger DevDay agent launches. Treat it as OpenAI’s answer to small specialized decision models like Jev.

Full text · 5,070 chars
- OpenAI launched the Decisions API at DevDay 2026, powered by new GPT-6 Luna model. - Luna picks from a developer-defined finite answer set given text or image context. - Built for classification, request routing, and choosing an agent's next action. - Currently in limited preview for selected API customers, with broad release in the coming days. - Complements the upgraded Agents API with computer use and Ultrafast tier at 300 tokens/sec. - Signals a shift toward task-specialized GPT-6 variants like Astra, Sol, and Luna. OpenAI’s Decisions API gives developers a constrained GPT-6 router OpenAI unveiled the DevDay recap Decisions API at DevDay 2026. The new endpoint uses GPT-6 Luna, a model variant tuned for real-time decisions with a fixed answer set. Developers provide a question, allowed answers, and text or image context; Luna returns one of those answers for the application to consume directly. The launch gives developers their first access to Luna, a distinct member of the GPT-6 family alongside Astra and Sol. Its narrow interface targets classification, routing, and agent-control tasks that otherwise require prompt constraints, structured-output validation, and recovery logic around a general-purpose model. One call, one allowed choice Each Decisions API request defines the decision Luna must make and the answers it may select. The finite answer space lets an application validate the result against the same categories it supplied, without parsing a free-form response. | Request element | Purpose | |---|---| | Question | Defines the decision to make | | Allowed answers | Sets the choices Luna may return | | Context | Provides relevant text or images | | Result | Returns one answer from the declared set | OpenAI’s example routes a support ticket by sending its contents with a list of eligible teams. Luna evaluates the request and returns the selected team. The underlying task is classification, with a GPT-6-family multimodal model evaluating the context. Why specialization trims the stack General-purpose chat models can already classify requests, but production integrations often need prompts that prohibit extra text, schemas that constrain the response, parsers that extract the label, and retries for invalid categories. Luna folds the allowed answer set into the API contract, reducing the amount of application code required to enforce valid output. A valid label can still be incorrect when an input is ambiguous, adversarial, or outside the supplied taxonomy. Applications that require abstention should include an explicit option such as needs_review or unknown, then route that result to a separate workflow. Likely workloads - Routing support tickets, email, and sales leads to queues or teams - Assigning content to a defined set of moderation labels - Selecting an agent’s next tool or workflow step from an allowlist - Classifying product images, forms, receipts, and other documents - Making frequent branching decisions inside multi-model pipelines Luna’s place in GPT-6 OpenAI also announced GPT-6.1 Sol, an upgrade focused on agentic coding, computer use, and professional work. The company says Sol delivers performance near Astra at one-fifth of Astra’s standard input and output token prices. An Ultrafast tier offers up to eight times faster generation in Codex, reaching 300 tokens per second, and up to six times faster generation through the API. Luna serves a different workload within that lineup: bounded selections made repeatedly and quickly. A larger model can plan a task or generate an answer, while Luna chooses the next tool, destination, or policy label from a declared set. A natural fit for agent loops The Decisions API can complement the upgraded Agents API guide, which now covers agents that operate software through computer use. Those systems repeatedly choose among actions such as clicking, typing, calling a tool, requesting approval, or stopping. Luna provides a constrained decision point for workflows that expose those actions as allowed choices. The preview leaves key blanks The Decisions API is available to selected API customers in limited preview. OpenAI says a broader release will follow in the coming days, but it has not published Luna’s pricing, rate limits, latency measurements, regional availability, or maximum number of choices per request. Production suitability will depend on latency and classification quality under real traffic. Routing and agent-control systems may call the endpoint at every branch, so tail latency matters alongside average response time. Evaluations should also measure how often Luna confuses neighboring labels, selects a fallback category, or changes its answer when context contains irrelevant or hostile instructions. Teams testing the preview can shadow existing classifiers, record a confusion matrix for each taxonomy, and compare cost and latency at realistic request volumes. Those results will show whether Luna can replace prompt-and-parse pipelines, conventional classifiers, or fine-tuned models for a given workload.

NVIDIA's BigVGAN v2 Hits 44.1 kHz Audio With 3x Faster CUDA Inference

A new audio renderer can turn a compact spectrogram into CD-rate sound faster on a single data-center GPU. NVIDIA’s BigVGAN v2 flagship is about 122 million parameters at 44.1 kHz with 512× upsampling from 128-bin mels. Other v2 checkpoints cover 22.05 and 24 kHz and sit around 112 million parameters. A fused CUDA path is reported 1.5× to 3× faster than stock PyTorch on one A100. Training used a multi-scale sub-band CQT discriminator and multi-scale mel loss for 5 million steps on multilingual speech, music, instruments, and environmental sound. Hugging Face from_pretrained is documented; 100+ Spaces including Seed-VC and MMAudio are named. Pipeline speed still depends on mel generation and encoding. The rest is paywalled.

- NVIDIA released BigVGAN v2, a 122M-parameter neural vocoder at 44kHz with 512x upsampling. - Custom fused CUDA kernel delivers 1.5 to 3x faster inference on a single A100. - Trained with multi-scale sub-band CQT discriminator and multi-scale mel spectrogram loss for 5M steps. - Training data spans multilingual speech, environmental sounds, and musical instruments, not just English speech. - Hugging Face integration lets you load and run with from_pretrained in a few lines. - Already embedded in 100+ Spaces including Seed-VC and MMAudio pipelines. BigVGAN v2 adds 44.1 kHz vocoding and faster CUDA inference NVIDIA’s BigVGAN v2 release adds pretrained neural vocoders for 22.05, 24, and 44.1 kHz audio. The flagship checkpoint converts 128-bin mel spectrograms into 44.1 kHz waveforms, using 512 waveform samples for each mel frame. A custom CUDA extension accelerates the anti-aliased activation blocks that perform much of the generator’s work. A neural vocoder handles the final stage of many speech, music, voice-conversion, and video-to-audio pipelines. It receives a compact time-frequency representation called a mel spectrogram and synthesizes the raw samples sent to an audio file or playback device. Its speed and accuracy directly affect end-to-end latency, high-frequency detail, and audible artifacts. A wider training set meets a fused kernel - Five v2 configurations are provided in the pretrained models. The published checkpoints cover 22, 24, and 44 kHz output with 80, 100, or 128 mel bands. - Fused CUDA inference. NVIDIA reports a 1.5x to 3x speedup over the standard PyTorch path on a single A100 GPU. - Reworked objectives. Training adds a multi-scale sub-band constant-Q transform discriminator and a multi-scale mel-spectrogram loss. - Broader source audio. NVIDIA describes a large compilation spanning multilingual speech, music, instruments, and environmental sounds. The 44.1 kHz model with 512x upsampling contains about 122 million parameters and was trained for five million steps. The other v2 checkpoints contain about 112 million parameters. NVIDIA’s speed figure measures the generator’s fused CUDA path; complete pipeline throughput also depends on mel generation, data transfer, batching, and audio encoding.

SYSTRAN's Faster Whisper Medium Transcribes 99 Languages 2.4x Faster

You can run the mid-size speech model faster and on less video memory without changing the official weights. SYSTRAN’s faster-whisper-medium is a CTranslate2 conversion of OpenAI’s Whisper medium (769 million parameters). The project claims up to 4× faster transcription than reference Whisper at matching FP16 accuracy. FP16 on GPU and INT8 on CPU or GPU cut VRAM 30–40%. It covers 99 languages, is MIT licensed, and ships Silero VAD. WhisperX plus 26+ Hugging Face Spaces; over 830,000 downloads. The published timing table uses Whisper large-v2 on an RTX 3070 Ti 8 GB: openai/whisper FP16 batch 1 in 2m 23s at 4,708 MB versus whisper.cpp plus Flash Attention in 1m 05s at 4,127 MB. Exact text can still drift with decode settings. The rest is paywalled.

- SYSTRAN's faster-whisper-medium is a CTranslate2 conversion of OpenAI's Whisper medium checkpoint. - Delivers up to 4x faster transcription than reference Whisper with identical FP16 accuracy. - Supports FP16 on GPU and INT8 on CPU or GPU, cutting VRAM by 30-40%. - Covers 99 languages, MIT licensed, ships with built-in Silero VAD filtering. - Powers WhisperX and 26+ Hugging Face Spaces; over 830K downloads to date. - Runs via the faster-whisper Python package with a minimal transcribe API. Faster Whisper Medium speeds up multilingual transcription SYSTRAN converted OpenAI’s Whisper medium checkpoint to CTranslate2, giving developers a faster, lower-memory way to run the same 769-million-parameter speech model. The converted checkpoint targets self-hosted transcription systems where latency, throughput, and GPU memory determine serving cost. Whisper medium supports 99 languages, multilingual transcription, and speech translation into English. Its size places it between the cheaper small checkpoints and the more demanding large family, making it a practical candidate for subtitles, meetings, voice applications, and dataset labeling. CTranslate2 reshapes inference The repository stores the learned parameters from OpenAI’s upstream model in the format used by CTranslate2. That inference engine uses optimized kernels, decoder caching, kernel fusion, and low-precision computation to reduce runtime overhead. FP16 execution preserves the original model parameters and generally provides comparable accuracy. Exact transcripts can still vary with decoding settings, numerical precision, hardware, and runtime versions. INT8 modes reduce memory use further, with a possible accuracy cost that should be measured on representative audio. The benchmark gap, in numbers The faster-whisper project’s published benchmark transcribes 13 minutes of audio with Whisper large-v2 on an NVIDIA GeForce RTX 3070 Ti 8 GB. Although the test uses a larger checkpoint, it shows how the CTranslate2 runtime behaves under comparable decoding settings. | Implementation | Precision | Batch size | Time | Maximum VRAM | |---|---|---|---|---| | openai/whisper | FP16 | 1 | 2m 23s | 4,708 MB | | whisper.cpp with Flash Attention | FP16 | 1 | 1m 05s | 4,127 MB | This story is for Pro members You've reached the end of the free preview.

The Sequence Knowledge - Issue 941: Learning RSI: The Model Is Frozen. The System Is Not.

Your agent can get better all quarter even when the model’s weights never move. The Sequence’s RSI series says improvement lives in three places and only one is the trained model. Parts 1–2 covered the labs’ weight flywheel. This issue is about the other two layers — the system around a frozen model — where the author says most of the user-visible gain in 2026 actually happens. The stored page ends before those two layers are named in detail.

Full text · 801 chars
Here is an experience you have probably had by now. You set up an agent in the spring. Same model all quarter, weights frozen solid, not a single gradient step. And yet by summer the thing is noticeably better at your workflows. Fewer dumb mistakes, better tool choices, less babysitting. Nothing learned anything, in the technical sense of the word. So what improved? The answer is that improvement has three places to live, and only one of them is the model. Parts 1 and 2 of this series were about the bottom layer, the weights, where frontier labs run their industrial flywheel. This essay is about the other two layers, because that is where most of the user-visible improvement of 2026 actually happens, and because the mechanics up there are strange, underrated, and occasionally uncomfortable.

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. Coming soon: our 2026 list of Climate Tech Companies to Watch With the planet nearing 1.5 °C of warming, climate policies being unraveled, and Big Tech backpedaling on its climate ambitions, it can be tempting to give in to climate doom and defeatism. But despite the headwinds, the world has still made incredible progress. That’s why MIT Technology Review publishes its annual list of Climate Tech Companies to Watch. Once a year, we compile a list of 10 companies that we believe have done the most, or have the best chance, to make a real dent in emissions or improve public safety and health. We’ve now finalized our 2026 list and will publish it on October 6. It features companies making strides in energy storage, nuclear power, transportation and other areas despite today’s regressive climate politics. We hope you’ll enjoy the package and perhaps come away feeling a bit more hopeful about our climate’s future. Here’s what to expect. —James Temple Subscribe to receive full access to this year’s list, and keep reading The Download to be among the first to see it. When can we say AI made a scientific discovery? Last week, Anthropic announced that its new molecular biology lab had made its first discovery: its AI agents had flagged a previously uncatalogued pattern surrounding an enzyme, a pattern “reminiscent” of what led to the gene-editing technology CRISPR. But the claims angered biologists. Some questioned whether merely finding the pattern amounted to a discovery at all. Another said his team had already discovered the same pattern, raising questions about whether Anthropic’s system had learned from his conversations with Claude. It’s a reminder that what’s novel for AI may be routine, unsurprising or simply not that consequential to a biologist.

Hi folks, I’ll be at OpenAI DevDay today. If you’re there, come say hi - I have pink shoes on. Sam says they've "found a new thing". I have the embargo of all the things they’re launching but I’m sworn to secrecy and I’d like to be invited back, so I wont divulge, but rumours are going around X and some things are what we are expecting… I also have my Stanford talk later today, and I’ve been up since 2am 😩, I don’t usually suffer with jet-lag so what a great day for it 🙃. Also only in SF… I was at the hotel bar last night and a woman next to me said what tool is that? I proudly said oh I built it - it’s the course platform I built. So now I’m friends with someone at Deepmind. Ben’s Bites is brought to you by Google Cloud Google Cloud starts Season 3 of Advent of Agents this Thursday, Oct 1: one question a day about running agents securely in production, from agent identity to kill switches, with a short video and code you can build with your coding agent. Get Day 1 in your inbox. Headlines Anthropic released Claude Sonnet 5.5 - Sonnet 5.5 looks like a capable model based on benchmarks - close to Opus 5.5 in coding and a big jump in understanding images/charts etc. If you’re on the $20 plan, try replacing some of your usual asks from Opus to Sonnet 5.5 at high thinking. Sonnet used to be my jam - I always used it before Opus 4.5. But I hadn’t touched it since, but I’m seeing a lot of good reviews for this one so I’ll definitely take it for a spin. But in Pi and Droid, never in Claude Code - idk if it’s just me but I just cannot get on with their harness at all. ps: Anthropic has a track record of making the .5 version of Sonnet models really good. Manus 2.0 and Cue. Manus is back with a video editor, a game builder and the boring old automations (via email, Slack, calendar, etc.). Cue is their take on consumer agents: each one gets its own email, phone number, wallet and compute, just like Grok Bot, Muse and the others. Free in early access (code MEETCUE might work). GPT-6 Astra is uniquely great at using a computer/browser. I asked Opus 5.5 (which I’m enjoying as my daily) to do some tasks in Chrome, and it was way worse than Astra (or any GPT model tbh). Here’re some examples of using it every day. OpenAI also fixed a bug that was making GPT-6 Sol and Luna worse at it (and image understanding in general). OpenAI’s agents keep breaking out and “hacking” websites. Recently, they took a sneak peek into some Australian Govt websites. News outlets have a tendency to exaggerate what’s hacking or not, but here’s the official link to follow if you wanna keep up with the dirty deeds by these agents.

Photo Scrubber — local face blur & metadata removal

Full text · 393 chars
29th September 2026 I took a photograph of some protesters, then thought about how I don't like sharing photographs of strangers with identifiable faces. I had GPT-6 Astra build this experimental tool that would identify faces and automatically blur them out. It uses Google's MediaPipe C++ library, compiled to WebAssembly via @mediapipe/tasks-vision, plus the BlazeFace face detection model.

😺 OpenAI DevDay 2026 Watch Party Grant + Corey react live to every major OpenAI DevDay announcement. Welcome, humans. OpenAI DevDay 2026 starts today. We’re watching it with you. OpenAI is about to spend a keynote showing us what it thinks developers should build next. New models? New agents? New APIs? A demo that makes Grant start yelling at the screen? All very possible. So instead of waiting for the post-event summaries, Grant Harvey and Corey Noles are going LIVE for a DevDay watch party and reacting to the keynote as it happens. When to join Right now! we just went live. OpenAI’s keynote starts at 10:00 AM PT / 12:00 PM CT / 1:00 PM ET and features Sam Altman, Romain Huet, Tejal Patwardhan, and Holly Li. We’ll keep OpenAI’s stream up, react in real time, and translate the demos into normal-person English while they’re still happening. What we’re watching for - New models: anything that changes the capability, speed, price, or usefulness of what developers can build (this is unlikely, per WSJ, but idk). - Agents: especially tools that can do work across apps, APIs, browsers, or computers instead of only answering prompts (this should be called “dot”). - Developer tools: APIs, SDKs, coding workflows, infrastructure, and anything that makes AI easier to ship inside real products. - The demo-vs-reality gap: what actually looks useful versus what merely looks great on a keynote stage. - The weird surprise: because there is almost always one announcement nobody had on the bingo card. The point: by the end, you should know what OpenAI actually announced, what changed, and which parts are worth paying attention to after the livestream ends. And yes, if you miss the beginning, the recording will live at the same link. 📚 Want the official source open too? Yep, there are a few official OpenAI pages worth having open next to the watch party: - OpenAI DevDay 2026: the main event page, full agenda, keynote timing, and event details. - Official OpenAI YouTube livestream: the actual keynote stream from OpenAI. This is the direct link to use if you want the raw event alongside our watch party. - DevDay keynote community post: OpenAI’s developer-community announcement for the stream. - DevDay Exchange: OpenAI’s page for the follow-on developer events in Bengaluru, Tokyo, Seoul, Berlin, Paris, London, São Paulo, and Mexico City. 👀 What’s already happening before Sam hits the stage OpenAI is not exactly setting expectations low. The official YouTube description says Sam Altman, Romain Huet, Tejal Patwardhan, and Holly Li will unveil 20+ launches, debut new capabilities, and demo new breakthroughs for the first time. - The day is much bigger than the keynote: OpenAI Developers posted an agenda with five stages and 22 breakout sessions running after the keynote. One Codex session teases an internal agent that spent 1,000+ hours keeping builds and tests passing. - Sam’s pre-show teaser: OpenAI has “built some great stuff for you.” That is the entire product preview. Very helpful for the bingo cards, Sam. - OpenAI’s morning message was even more specific: “10am PT, on the dot.” Subtle! - Meanwhile, the subscription drama is already live: Tibo says Pro $200 is reopening, but its usage math now works out to about half the API-dollar spend of the old Pro $200 plan. He also says DevDay will add still-unrevealed subscription features that do not draw on usage. So the thing to watch is not merely “how many things did OpenAI launch?” It is which launches actually change what you can do, what they cost, and whether those new subscription perks make the new limits feel any less painful. 🎥 While you wait, catch up on the chaos GPT-6 Sol vs. Claude Opus 5.5, Round 2 We stopped asking the models trivia questions and made them build things: a black-hole simulator, a Blender world, harder games, and increasingly cursed versions of Cat Doom. Why AI infrastructure is more than “more GPUs” CoreWeave EVP Chen Goldberg joined Corey to explain why modern AI infrastructure behaves less like a pile of chips and more like one enormous computer. One more before you go: If OpenAI drops anything truly ridiculous today, there is a very good chance Grant and Corey will try to break it live. For science, obviously.

OpenAI's Dots Turns ChatGPT Into a Persistent Agent That Works While You Sleep

Full text · 7,385 chars
- OpenAI launched dots at DevDay 2026, always-on agents powered by GPT-6 Astra. - Each dot gets its own cloud computer, browser, and persistent memory across ChatGPT, Slack, and Teams. - Dots can triage bugs, scope builds, and ship PRs via Codex integration for developers. - Rolling out to Pro, Business Premium, and Enterprise; usage free of plan limits for one month. - Read-only proactive research by default; sensitive actions require explicit approval or custom rules. - Ships on GPT-6 Astra after OpenAI scrapped GPT-6.1 Astra over safety concerns. OpenAI Dots put persistent agents inside ChatGPT OpenAI has introduced Dots, a type of ChatGPT agent that can continue working after a conversation ends. Powered by GPT-6 Astra, each dot receives a persistent cloud computer, browser, memory, and access to approved apps. It can monitor ongoing work, launch tasks, and return results for review without waiting for another prompt. The release extends ChatGPT from request-and-response sessions into long-running software workers. A dot remains available across supported interfaces and can pursue user-defined goals in the background, subject to permissions and approval checks. One agent across several channels Each dot has a customizable name, avatar, and handle such as @yourname-dot. OpenAI says it can connect to thousands of apps, retain project context, run scheduled tasks, and use its cloud browser to complete web-based work. The same dot can receive messages in ChatGPT, Slack, and Microsoft Teams, as well as through voice calls. Its memory follows it across those surfaces, allowing a conversation started in Slack to inform later work in the ChatGPT desktop app. A dot can also divide work among background agents, open parallel cloud threads, and create Codex tasks on a connected computer. For development work, it can operate in a Codex cloud environment linked to a repository. When a website blocks cloud browsers or requires authentication, the dot can request a private sign-in flow or return browser control through a Take over button. The work Dots can absorb OpenAI’s initial examples focus on recurring development and operations work that spans several tools: - Triaging bug reports and feature requests from connected apps. - Investigating failing builds and scoping improvements against team priorities. - Building and testing changes with Codex, then returning completed pull requests for review. - Monitoring several projects and carrying relevant context between supported channels. Users can inspect a dot’s cloud computer while it works or grant access to a local machine. Local access requires a separate permission from Codex and Work Sync, and each account can link one personal computer at a time. Work continues between messages A dot tracks task progress, determines when work should pause or resume, and decides when user input is required. During idle periods, it can search approved sources with read-only access for updates relevant to its assigned goals. Actions that modify an account, send information, or change external systems require the appropriate integration permission or explicit approval. The operating model separates proactive research from state-changing actions that carry greater risk. Memory draws from three sources: the current conversation, the user’s ChatGPT memory, and private notes maintained by the dot. Those notes can contain preferences, prior decisions, and unresolved tasks. Because they persist across channels, instructions given in one interface can affect later behavior elsewhere. Actions pass through approval checks Before a dot changes an account or shares information, an automated review determines whether it may proceed, must request approval, or needs to hand control to the user. Custom rules can require draft review before messages are sent, although those rules cannot override OpenAI’s built-in safety requirements. | Situation | Expected control | |---|---| | Background research | Read-only access to approved sources | | Account or system change | Integration permission or explicit approval | | Login or sensitive browser step | Private sign-in flow or user takeover | | Outbound communication | Automated review plus any user-defined draft rule | Ahead of the conference where it introduced Dots, OpenAI said it had canceled plans to debut GPT-6.1 Astra, citing elevated risk after recent incidents involving autonomous hacking. Dots use the existing GPT-6 Astra model. OpenAI also released GPT-6.1 Sol, a lower-cost model described as approaching Astra’s capability. Paid tiers get the first rollout Access depends on the user’s plan, region, device, and workspace settings: | Plan or platform | Availability | |---|---| | Pro and Business Premium | Rolling out in eligible markets | | Enterprise | Available worldwide after a workspace administrator enables it | | Restricted regions | Pro access excludes the EEA, UK, and Switzerland at launch | | Age requirement | Pro access excludes users under 18 | | Mobile apps | Supported after the dot is created on desktop | | Mobile web | Unsupported at launch | Conversations with a dot do not consume ChatGPT usage allowances. Tasks launched through Work or Codex draw from those products’ quotas. OpenAI says eligible plan allowances will not be charged for usage during the month following launch. Bloomberg also reported that OpenAI introduced a $500 Pro tier alongside the release. Persistence changes the agent architecture Most agent frameworks, including products built with the Agents API, represent work as bounded runs: a request starts, tools execute, and the run ends. Dots add a long-lived agent object whose conversations serve as entry points into the same workspace. Its browser sessions, files, memory, and task state can survive across interactions. For developers, that architecture changes the operational requirements. Persistent per-user virtual machines raise questions about idle compute costs, tenant isolation, credential storage, software patching, audit logs, cancellation, and recovery after partial failures. Cross-channel memory also requires clear controls for retention, deletion, and access boundaries. Dots place OpenAI in the growing market for persistent assistants, including Meta’s Muse. The immediate competitive focus is practical work across existing tools, such as responding to a bug reported in Slack, preparing a pull request, or sending an overlooked invoice after the required approval. Production limits remain Teams connecting a dot to production systems need to account for several documented constraints: - Stopping a task does not reverse actions that have already completed. - Dots can make mistakes even when approval rules are enabled. - Some websites block cloud browsers, requiring access through a connected local machine. - Pausing the main task does not cancel delegated background work or scheduled runs. - Local access works only while the ChatGPT app is open and the linked computer is online. For teams building agent products, Dots provide a concrete implementation of a cloud-resident agent with a dedicated workspace, cross-channel memory, app integrations, parallel execution, and approval controls. Evaluating the product will depend on how reliably those components handle long-running work, partial failures, sensitive credentials, and human review.

Cursor Lets Developers Visualize Data Inline During Agent Chats

Full text · 3,809 chars
- Cursor added /visualize, a slash command that renders charts and diagrams inline in the chat. - Available now in the Agents Window for all Cursor users, no separate pricing. - Extends the earlier Canvas feature, which renders persistent React artifacts beside the chat. - Targets quick data analysis where a full dashboard would be overkill. - Useful for query results, log files, and architecture or sequence diagrams during planning. - Complements MCP integrations like Datadog, Databricks, and Sentry for observability workflows. Cursor adds inline charts and diagrams to agent chat Cursor has added a slash command that renders charts and diagrams inside agent conversations. In the Agents Window, users can type /visualize and direct the agent to data from a file, query, log, or connected tool. The result appears inline rather than as a long Markdown table or code block. The command extends Cursor’s visual interface work into quick, conversational analysis. Cursor previously introduced Canvas, which lets agents build interactive dashboards in a side panel with React-based components for tables, charts, diagrams, and layout. /visualize brings a narrower version of that capability directly into the chat thread. From tool output to chart Agents can retrieve data from databases, local files, observability platforms, and MCP servers. MCP, or Model Context Protocol, gives an agent structured access to external tools and data sources. Those workflows often produce tables that preserve exact values but make trends, outliers, and relationships difficult to spot. Inline visualizations suit several common development tasks: - Plot query results from a database or MCP-connected service. - Inspect distributions in a CSV, benchmark result, or debug file. - Compare latency, error rates, or resource use across time windows. - Draft architecture, dependency, or sequence diagrams during planning. - Review incident data without moving it into a notebook or BI tool. Developers can invoke the command after the relevant data enters the conversation and specify the desired view, such as a line chart, distribution, comparison, or diagram. A clear request should include the fields to plot, the grouping or time range, and any labels needed to interpret the result. Where Canvas takes over The Agents Window serves as Cursor’s hub for running agents across local repositories, worktrees, cloud environments, and remote SSH sessions. Canvas artifacts occupy durable panels alongside tools such as the terminal and browser, while /visualize keeps a quick result within the conversation. | Task | Recommended tool | |---|---| | Inspect a query or metric once | /visualize | | Build and refine a reusable dashboard | Canvas | | Create a persistent interface with custom controls | Canvas | | Sketch a diagram during an agent conversation | /visualize | | Maintain repository-linked documentation | Canvas skill | Canvas remains the stronger fit when a visualization needs continued editing, custom interactions, or reuse. The slash command reduces the setup required for exploratory work and short-lived debugging questions. Rollout, cost, and open details /visualize is available in the Agents Window for Cursor users and requires no separate setup. Cursor has not announced an additional fee for the command; its requests use the same agent workflow as the surrounding chat. The initial announcement does not specify supported chart types, export formats, accessibility options, or whether inline visualizations can be saved independently from a conversation. Those details will determine how well the command fits reporting and documentation workflows. Its immediate use is clearer: developers can turn agent-accessible data into a visual check without transferring the results to another tool.

NVIDIA's Physis-Lang Teaches Video AI Real Physics, Beats Google's Veo 3.1

Full text · 7,040 chars
- NVIDIA released Physis-Lang, a self-evolving framework adding physics reasoning to video captions and prompts. - Cosmos 3 Super and Nano with Physis-Lang take rank 1 and 2 on Physics-IQ Verified at 48.2% and 43.3%. - Adding physics reasoning to prompts alone lifted Cosmos 3's PhyGenBench score by 5.62 points with no retraining. - A physics-aware critic evolves captioning guidelines; failures drive language-guided retrieval of missing physical phenomena. - New PhysCapBench evaluates caption quality across 246 videos and 3,794 human-verified atomic assertions. - Gains generalize across Wan 2.1 14B and all Cosmos 3 sizes, from 4B Edge to 64B Super. NVIDIA’s Physis-Lang teaches video models through physics-aware captions NVIDIA researchers introduced Physis-Lang, an open framework that encodes physical explanations in the captions and prompts used by video-generation models. The work targets a persistent weakness in generated video: realistic frames can still show butter melting upward, blocks passing through one another, or cloth moving without plausible weight and tension. Training captions provide supervision about objects, actions, and temporal changes. Physis-Lang enriches that supervision with cause, governing principle, and effect. A melting-butter caption, for example, describes heat raising the temperature, the material changing phase, gravity deforming the softened mass, and a liquid pool forming. The framework uses this language to recaption training videos and expand user prompts before generation. Better prompts lift physics scores In the reported Physics-IQ Verified snapshot, Physis-Lang configurations of Cosmos 3 Super and Cosmos 3 Nano occupy the top two positions. The benchmark evaluates how faithfully generated videos follow real-world physical behavior. | Reported Physics-IQ Verified results | | |---|---| | Configuration | Score | |---|---| | Physis-Lang with Cosmos 3 Super | 48.2% | | Physis-Lang with Cosmos 3 Nano | 43.3% | | Cosmos 3 Super baseline | 42.7% | | Seedance 2.5 | 42.4% | An inference-only ablation isolates the effect of prompt expansion. Adding physics-aware reasoning to the input increased Cosmos 3’s PhyGenBench score by 5.62 points with fixed model weights and no additional training. This path can be applied to an existing checkpoint because it changes the conditioning text sent to the generator. A critic rewrites the captioning rules The framework shares one physical-language representation across three connected stages, allowing critic feedback and failure-driven retrieval to improve the text used for training and generation. - Refine the language. A physics-aware critic checks each caption for missing claims and statements unsupported by the video. An agent updates the captioning guidelines, while the captioner remains frozen during this loop. - Retrieve weak phenomena. Failed generations become search queries. Language-guided retrieval selects visually diverse videos covering the physical categories where the system performs poorly. - Train and generate. The revised guidelines recaption training data and expand inference prompts. Scene-specific negative descriptions identify implausible dynamics for the generator to suppress. PhysCapBench measures whether the captions improve independently of video generation. The benchmark contains 246 reviewed videos and 3,794 human-verified physical assertions, averaging 15.4 assertions per video. Evaluators split each generated caption into atomic claims, check those claims against the source video, and calculate precision, recall, and F1, which balances the two. | Results across nine caption-guideline iterations | | | |---|---|---| | Metric | Initial score | Final score | |---|---|---| | PhysCapBench caption F1 | 78.64 | 87.82 | | Downstream PhyGenBench | 64.17 | 67.29 | Failures choose the next training clips On VideoPhy-2 Hard, targeted retrieval raised joint scores in all eight reported categories.

The full pipeline also uses recaptioned data and failure-driven retrieval, so its results reflect the combined effect of language refinement, data selection, training, and inference-time prompting. The quantitative evidence covers selected benchmark phenomena, and the top Physics-IQ Verified score remains 48.2%. General simulation ability, long-horizon consistency, and performance on unseen physical processes remain open evaluation questions. Held-out phenomena and human review would help determine how well the gains transfer beyond the reported test sets. Captions become a control surface Physics-aware captions give developers a model-agnostic way to supply causal structure. A caption that names forces, state changes, and expected outcomes provides more temporal guidance than a surface description of visible objects and actions. The approach operates at the data and prompt layers, allowing it to sit on top of existing checkpoints. An implementation can begin with inference-time prompt expansion: define a domain-specific causal schema, expand incoming prompts, keep the generator fixed, and evaluate on a held-out suite. Training integration adds critic-guided recaptioning, retrieval of failure cases, and another model-training run. The same workflow can be tested in other conditional generative systems that use scene descriptions. The project page and paper provide the framework details, benchmark definitions, ablations, and generated-video galleries covering collisions, tearing, wetting, and deformation under load.

OpenAI DevDay Drops Sol, Ultrafast, and Cloud Codex for Developers

Full text · 6,862 chars
- GPT-6.1 Sol lands at a fifth of GPT-6 Astra's token price with near-Astra coding performance. - Ultrafast tier pushes up to 300 tokens/sec, 8x faster in Codex and 6x in the API. - Codex now runs in reusable cloud environments, steerable from phone or any device. - Refreshed Codex CLI adds voice control, an /agents view, and better worktree support. - New code review in ChatGPT desktop inspects diffs on GitHub and GitLab PRs. - Plugin extensions plus MCP Events let plugins claim sidebar UI and trigger on app events. OpenAI DevDay 2026 puts agents in the cloud and adds a faster API lane Among the more than 20 announcements in OpenAI’s DevDay recap, five directly affect how developers build and operate agents: a lower-cost reasoning model, a premium API service tier, cloud-hosted Codex, new review tools, and richer ChatGPT plugins. The releases target the recurring constraints of agent development: model cost, response latency, execution environments, human oversight, and integration with external systems. Sol lowers the cost of long agent loops GPT-6.1 Sol is OpenAI’s new mid-tier reasoning model for agentic coding, computer use, and multi-step workflows across applications. OpenAI positions its performance near GPT-6 Astra while charging one fifth of Astra’s standard input and output token prices. Agent workloads multiply token usage as they plan, call tools, inspect results, and retry failed steps. Sol’s lower rates can support longer runs within the same budget, although teams should validate task quality and retry rates against their own evaluations before switching models. GPT-6.1 Sol is available now through the API and on Plus, Pro, Business, Enterprise, and Edu plans. Ultrafast buys back response time Ultrafast is a premium service tier that accelerates supported models. OpenAI reports up to eight times faster generation in Codex, reaching as many as 300 tokens per second, and up to six times faster generation through the API. GPT-6 Astra supports Ultrafast now, with Sol support planned. API calls opt into the tier individually by setting service_tier to ultrafast, which allows applications to reserve the added cost for interactive requests while leaving batch and background jobs on the standard tier. from openai import OpenAI client = OpenAI() resp = client.responses.create( model="gpt-6-astra", service_tier="ultrafast", input="Explain why the sky is blue in one sentence.", ) print(resp.output_text) OpenAI recommends using Ultrafast over WebSockets because a persistent connection avoids repeated connection setup and reduces network overhead across tool-heavy agent loops. The synchronous example above shows the request flag; production latency tests should use the WebSocket path described in the Ultrafast docs. Default limits start at 500,000 tokens per minute for usage tiers 1 through 3 and rise to 5 million tokens per minute at tier 5. Processing is limited to US and global regions, with no EU regional endpoint currently available. Teams with residency requirements should resolve that constraint before adoption and compare the tier’s premium pricing with measured latency gains. Codex leaves the laptop Codex can now execute locally, in OpenAI’s cloud, or remotely under control from another device, including a phone. Reusable cloud development environments preserve approved settings, dependencies, and permissions, reducing startup time and giving teams a shared execution setup. A developer can launch a migration from a laptop, monitor it from a phone, and continue steering it from another computer. The rebuilt Codex CLI adds several controls for longer and more concurrent sessions: - Voice input for starting and steering tasks from the terminal - An /agents view for delegating and tracking concurrent work - Improved Git worktree handling, prompt editing, and session resume - A cleaner terminal interface for long-running sessions Codex reviews branches before merge The new desktop review flow lets developers open a pull request or merge request in the ChatGPT Work or Codex desktop app, read a summary, inspect the diff, and question Codex about specific changes before posting feedback to GitHub or GitLab. It can also review an unshared branch before a pull request exists. Cloud review mode can produce an initial set of findings while the developer is away, shortening the manual review pass when work resumes. OpenAI says the feature is available on every plan. Plugins gain screens and triggers Plugin extensions expose the platform OpenAI uses for its own ChatGPT integrations. Third-party plugins can now occupy a sidebar position, render interactive panels beside a conversation, and provide custom viewers for product-specific file formats. OpenAI has also added clearer feedback to the submission review process. OpenAI also supports the proposed Model Context Protocol Events specification. MCP standardizes connections between AI clients and external tools; Events allows a connected application to send a notification that starts an automation. A project board could emit an event when a task appears, prompting ChatGPT to read linked documents and draft an implementation plan. Event-driven integrations require controls beyond prompt design, including least-privilege credentials, event deduplication, bounded retries, and audit logs. Because MCP Events remains a proposed specification, integrations should isolate protocol handling so later schema changes remain manageable. The agent stack stretches across surfaces - Model economics: Sol’s lower token prices can extend planning and correction loops without increasing the model budget at the same rate. - Request-level latency: Ultrafast makes generation speed a configurable API choice for endpoints where users are waiting. - Persistent execution: Cloud environments and remote controls allow Codex tasks to continue beyond a local terminal session. - Earlier review: Branch and cloud reviews move automated feedback ahead of the final human review pass. - Event-driven integration: Plugin panels and MCP events give ChatGPT both an interface for third-party software and a mechanism for responding to external changes. Roll out with benchmarks and guardrails - Evaluate Sol on real tasks. Compare completion quality, retries, token usage, latency, and total cost with the current model before changing production defaults. - Test Ultrafast over WebSockets. Measure median and tail time to first token, total completion time, tool-call latency, and cost on user-facing endpoints. - Pilot cloud Codex with scoped access. Pin environment dependencies, limit repository credentials, and define when agents may write, commit, or push code. - Design MCP event handlers for failure. Add idempotency, authorization checks, retry limits, and logs before allowing events to launch consequential workflows.

Making AI an asset, not an expense

Once chatbots are always on, paying per request can become a bill you cannot forecast — and this is a vendor arguing you should buy the computers instead. The HPE-sponsored piece says Deloitte’s 2026 State of AI found worker access up 5% in 2025, and the share of firms with at least 40% of AI projects in production is expected to double in six months. Ownership only wins past a company-specific crossover of steady use. Agent jobs can burn many model calls per task. It was not written by the magazine’s staff.

Full text · 5,737 chars
Sponsored Provided byHPE When customers talk about AI costs, the conversation usually starts with token prices and ends with access to the latest, most capable model in the cloud. Do they always need that level of capability? Not necessarily. But that is often where the conversation goes. As AI moves from experimentation to production, model choice is only part of the equation. When demand becomes steady and business-critical, a consumption-only approach can turn AI spending into a variable monthly line item that is difficult to forecast as usage, workloads, and model requirements change. At that point, the question is no longer simply which model to consume, or which provider offers the lowest token price: It is how to run AI economically, predictably, and at sustained scale. AI is moving from isolated pilots into production portfolios: assistants, retrieval-and-knowledge systems, and agentic applications. Customer-service, IT, research, and business-process agents can execute multi-step workflows across enterprise systems, creating recurring demand across models, data, and tools. This is already starting to happen. Deloitte’s 2026 State of AI in the Enterprise reflects what many leaders are seeing: worker access to AI rose 5% in 2025, and the share of companies with at least 40% of their AI projects in production is expected to double within six months. When AI becomes a portfolio of always-on workloads, not a collection of experiments, the economics change. Consumption pricing gives teams flexibility and limits commitment. But when usage becomes steady, predictable, and large enough to keep capacity productive, leaders need to ask a different question: Does it still make economic sense to buy AI one request at a time, or is it time to invest in capacity they can optimize and control? This is not an abstract cloud-versus-on-premises debate. It is a workload-by-workload business decision. Over the next 12 to 18 months, how much AI demand can the company reasonably expect? How consistently will that capacity be used? When multiple workloads share infrastructure, the enterprise can spread fixed costs across more productive use—improving the economics of ownership. The question is how much you run Ownership is not automatically the lower-cost answer. It only makes sense when an enterprise can keep capacity productive. Every organization has a crossover point, the level of sustained use at which owning capacity can become more economical than buying it one request at a time. There is no universal number. It depends on the models being used, the balance of input and output tokens, performance requirements, system design, energy costs, and the operating model required to support it. A retrieval-heavy knowledge system can have a very different cost profile from a simple assistant because it may process far more context for every interaction. Agentic workflows can be different again: a single business task may involve repeated reasoning, retrieval, model calls, and tool use. That is why generic cost benchmarks are not enough. Enterprises need to model their actual workloads, understand expected demand, and size capacity accordingly. At the right utilization level, the benefit is not only lower effective cost, but also greater predictability: the ability to manage AI capacity as a strategic infrastructure investment rather than watch a monthly spend line fluctuate with model use and workload demand. Ownership only works when it is put to work The capital decision is only half the equation. Even when the economics support ownership, capacity creates value only when the business gets workloads into production quickly and keeps them running. That takes more than installing infrastructure. It takes an operating model that connects the technology to adoption and business outcomes: bringing users and workloads on board, governing how AI is used, reviewing utilization, and continually identifying the next high-value use case. The goal is to create value early, then build on it. That means measuring use, identifying underutilized capacity, and bringing additional high-value workloads onto the platform over time. Without that discipline, the business may never realize the economic value that justified the investment. With it, AI capacity becomes a productive asset the business can optimize, expand, and use to create measurable value. Three questions to ask Before committing capital, leaders should ask three questions: - Is demand becoming steady, predictable, and large enough to justify dedicated capacity? - At what level of usage does ownership make economic sense? - Can we keep that capacity productive through adoption, governance, and continued use-case expansion? Make the shift deliberately As AI moves into production, the organizations that create the most value will look beyond token prices and the latest model. They will know when recurring demand calls for a different economic model—and they will have the operating discipline to make that capacity productive. That is when AI stops being an expense and becomes an asset. This content was produced by HPE. It was not written by MIT Technology Review’s editorial staff.

Coming soon: Our 2026 list of Climate Tech Companies to Watch

A magazine has locked its yearly climate-company shortlist and will print it next week. MIT Technology Review’s 2026 Climate Tech Companies to Watch publishes on October 6. Editors winnow a long list to 10 firms they think can cut emissions or improve safety. The UN, earlier this month, said the planet will tip past 1.5 °C “likely within the next few years.” The list itself is not in this preview. Themes named: energy storage, nuclear, transportation.

Earlier this month, the UN announced the planet will tip past 1.5 ˚C of warming, “likely within the next few years,” squashing any lingering hope that nations would cut emissions fast enough to achieve the loftiest goal of the Paris climate agreement. In the US, the world’s second-largest-emitting country, its leader continues to deny climate realities and unravel climate policies. Big Tech is backpedaling on its climate ambitions, as companies race to build massive AI data centers. And all this comes amid yet another season of shattered heat records, raging wildfires, and deadly floods. It can be tempting to give in to climate doom and defeatism. But despite the headwinds, the world has still made incredible progress. Companies are developing and deploying renewables, batteries, and EVs; inventing cleaner means of producing industrial goods; and devising ways to keep cities and people safe even in the face of more extreme weather conditions. Those advances will only accelerate as costs decline and people demand greater climate action, as well as all the economic and health benefits that come with it. Recognizing our ability to make such progress is why MIT Technology Review began publishing our annual list of Climate Tech Companies to Watch three years ago. Once a year the editors and writers use their deep industry knowledge and academic sources to compile a long list of companies around the world that are transforming the way we generate energy, produce goods, move people and things, or mitigate rising climate dangers. We then conduct several rounds of spirited newsroom debate to winnow that list down to 10 that we believe have done the most, or have the best chance, to make a real dent in emissions or improve public safety and health. We’re happy to say we’ve finalized that list for 2026, and will publish it on October 6. You can sign up for The Download newsletter to be among the first to see it, or subscribe to receive full access to this year’s list. It features a mix of companies making strides in energy storage, nuclear power, transportation, and other areas, including ones that have figured out how to continue to make progress amid the regressive climate politics of the moment. We hope you’ll enjoy the package and perhaps come away feeling a bit more hopeful that we can move fast enough to avoid the gravest dangers of climate change, and build a safer, healthier, and more sustainable world.
