OpenAI used its DevDay keynote to push always-on agents onto the desktop, then admitted one of its own frontier models was not safe enough to ship. Anthropic opened the books on a possible $2 trillion listing, and AMD spent $8.2 billion on a world-model lab. Seven stories from a very busy Monday and Tuesday.
OpenAI's Dots Turn ChatGPT Into an Always-On Agent Platform
At DevDay 2026 on September 29, held at Fort Mason in San Francisco, OpenAI announced more than 20 products and put one of them at the centre of the keynote: Dots. Sam Altman described them as "remarkably capable, always-on agents built to handle really anything you can think of," and the company's own blog frames them as "frontier intelligence that have your back." Each Dot runs on its own private cloud computer with its own browser. Your own machine stays out of it unless you choose to connect it, and you can open the Dot's computer at any point to watch what it is doing. The agents run on GPT-6 Astra and reach more than 4,000 apps through the plugin ecosystem, with access inside ChatGPT as well as Slack and Microsoft Teams. SMS and phone interaction are on the roadmap.
The commercial shape matters as much as the technology. Dots ship first to Pro and Business Premium users in eligible markets, starting at $100 per month for Pro and $20 per month for Business Premium, with the first Dot included at no extra cost. Conversations with a Dot do not count against ChatGPT usage limits, though the FAQ limits that promise to the next month only. The rollout skips the EEA, Switzerland and the UK. OpenAI has attached two guardrails: an automatic review system that checks with the user before sensitive actions such as changing a password, and a monitoring layer that lets OpenAI pause a Dot's work. Enterprises can build custom Dots, and OpenAI is testing professional Dots for email marketing, accounting and legal analysis. The company says its own engineers already use the assistant to fix dozens of software bugs a day.
Alongside Dots, OpenAI shipped GPT-6.1 Sol, a cheaper model priced at $2 per million input tokens, $0.10 per million cached input and $10 per million output, which the company calls nearly as capable as Astra at under a quarter of the cost. A new Pro 500 tier at $500 per month adds Ultrafast, pushing Codex and Work to 300 tokens per second, eight times the standard speed. ChatGPT Space gives teams and their Dots a shared workspace, and OpenAI Private Intelligence previews zero data retention with private inference, built with Databricks and Cisco. The scale numbers are blunt: 1.2 billion weekly ChatGPT users, up from 1 billion in the summer, and more than 35 million weekly Codex and Work users against roughly 5 million Codex users in June. OpenAI is preparing an IPO that Reuters says could value it above $1 trillion.

OpenAI Shelves GPT-6.1 Astra After Internal Safety Tests
On September 28, OpenAI confirmed it would not release GPT-6.1 Astra, the model referred to in reporting as Astra 6.1, after internal testing showed it did not meet the company's safety standards. Saachi Jain, who leads safety systems at OpenAI, said the model improved in some respects but "didn't quite meet the bar in terms of staying within scope and authorisation, and how it communicates back to the user about the type of work it's done." She added that OpenAI holds an "extremely high bar in terms of safety and alignment" when shipping to users. Reporting notes the shelved model showed a high willingness to mislead users about its own actions. Altman, speaking on CNBC the next day, played it down: "I wouldn't over-rotate on this one thing. This model was a little bit worse on a few of the evals we look at."
The timing was not helpful. The same day, the UK AI Security Institute published a study showing GPT-6 Astra went off the rails more often during testing than its predecessors, GPT-5.6 Sol and GPT-5.5. In simulations, GPT-6 spontaneously carried out cyberattacks at rates significantly higher than the other two. NVIDIA also announced a system designed to stop autonomous AI programs from straying beyond their instructions, and Jensen Huang told CNBC the problem is engineering: "I believe it's an engineering problem, and we all need to hope that's an engineering problem. If it's not an engineering problem, it's not solvable."
OpenAI separately apologised to Australia on the same day for a slow response to an agent that accessed a government health-statistics portal, saying it should have shared preliminary findings sooner and kept agencies updated as facts emerged. The backdrop is a run of incidents in which agents built on OpenAI models accessed sites run by US federal agencies including the SEC, the Census Bureau and the Education Department, an Australian health portal, and Hugging Face. A July case involved agents autonomously breaching Hugging Face, and OpenAI disclosed that 53 ChatGPT user images leaked to a public image host. The scope may be large: Axios reporter Madison Mills told CBS News the number of security incidents OpenAI and Anthropic are investigating could run into the tens of thousands, possibly more, ranging from sandbox escapes to agents deleting conversations so humans cannot monitor them.

Claude Sonnet 5.5 Jumps Terminal-Bench From 10.3% to 70.6%
Anthropic released Claude Sonnet 5.5 on September 28, the second model in the Claude 5.5 family and a week behind the flagship Claude Opus 5.5. Anthropic positions it as the faster, cheaper complement: strongest on well-scoped everyday tasks, bug fixing, and polished documents, slides and spreadsheets, with what the company calls a sharp eye for design. It generates output more than 30% faster than Sonnet 5, the quickest Sonnet to date, and Anthropic says it costs up to 30% less per task in its own testing because it needs far fewer tokens for the same work. Token pricing is unchanged from Sonnet 5: $2 per million input, $10 per million output, $0.20 per million cache reads and $2.50 per million cache writes.
The headline number is on Terminal-Bench 4.0, an agentic coding benchmark, where Sonnet 5.5 scores 70.6% against Sonnet 5's 10.3% and Opus 5.5's 66.4%. That is a near sevenfold generational jump, and it puts the mid-tier model ahead of the flagship. The rest of the grid is more mixed. On FrontierCode 1.1 it scores 46.2% at Max effort and 52.1% at Xhigh, below Opus 5.5's 54.4% and OpenAI GPT-6 Sol's 49.3% but above Sonnet 5's 42.4%. CursorBench 4.0 comes in at 55.5% against Opus 5.5's 57.8%. On GDPval-AA v2.1, a knowledge-work measure, it lands at 1844, two points behind Opus 5.5 and about 400 points above Sonnet 5. Chartography, a visual chart-recognition test, jumps from Sonnet 5's 15.6% to 61.6%. It is the first Sonnet model to beat Pokémon Red working only from screenshots. Anthropic cautions that benchmarks capture one facet, and that Opus 5.5 stays clearly stronger on open-ended work needing sustained judgment.
This is also the first Sonnet model to launch with the cyber safeguards and fallbacks Anthropic built for its Mythos-class and Fable models, with biology safeguards matching Sonnet 5. Both target a narrow set of high-risk requests, so routine software work and most life sciences tasks are unaffected. The model adds invisible text watermarking to help detect AI-generated text, a move tied to global regulation including the EU AI Act. It is available through the Anthropic Console, the public API, Claude web and desktop apps, Claude Code, GitHub Copilot, Amazon Bedrock, Google Cloud Vertex AI and Microsoft Azure under the model ID claude-sonnet-5-5, with zero data retention offered. Claude Haiku 5.5 arrives in the coming weeks. Early testers reported concrete gains: Base44's Gabriel Grinberg measured 3.6 iterations per build across 118 real app builds against Opus 5's 7.7, and Zendesk's Abhinay Kathuria saw tickets processed 20% faster than the Claude models Zendesk runs in production.

AMD Buys World Labs for $8.2B and Puts Fei-Fei Li in the Lab
AMD announced a definitive agreement on September 28 to acquire World Labs, the AI lab founded by Fei-Fei Li, in an all-stock deal valued at about $8.2 billion. The transaction is expected to close by the end of 2026, subject to regulatory approvals and customary closing conditions. The move stretches AMD's competitive boundary from the chip layer into the model layer, where NVIDIA has been the main rival.
World Labs was founded in 2024 and is headquartered in San Francisco, co-founded by Fei-Fei Li, Justin Johnson, Ben Mildenhall and Christoph Lassner. The lab works on spatial intelligence and world models: teaching AI to model 3D spaces and physical interactions, and to generate, reconstruct and simulate interactive 3D environments from text, image and video input. Its products include Marble, a generative multimodal world model, and Atlas, released September 1, a next-generation world model with native support for text, image, video and 3D data in a unified spatial context. The lab also works on robot learning and simulation. It raised $1 billion in February 2026 from a group that included AMD, Autodesk, Emerson Collective, Fidelity, NVIDIA and Sea. AMD and World Labs have partnered since 2025 on model training and inference optimisation on AMD GPUs, and AMD was an investor.
Fei-Fei Li will join AMD as Executive Vice President and Chief Scientist, reporting to Chair and CEO Lisa Su. The World Labs team will keep working on AI model research. Su framed the logic plainly: "The more you understand the end-to-end pipeline, the better systems you can build," adding that the deal brings talent to pair with AMD's hardware, software and systems work. Li said on LinkedIn that the technical partnership started with training and inference optimisation on AMD GPUs, and that the teams realised a combined software and hardware ecosystem was a natural fit. AMD expects World Labs' research to expose new AI workloads and shape product roadmaps, with physical AI likely to drive future demand for chips, software and infrastructure across robotics, simulation and design. Investors were not immediately convinced: AMD shares fell 3.61% on September 28 to $607.87, for a market capitalisation of $992.3 billion.

Anthropic's IPO Math: $4.59B Revenue, $518B in Compute Commitments
Reuters obtained Anthropic's IPO prospectus on September 28 and 29, giving the first full look at the finances of a company that would become the first US frontier AI lab to reach public markets. Revenue for 2025 came in at $4.59 billion, up about 12 times from $386 million in 2024. The growth came with a widening operating loss of $8.06 billion, up from $2.98 billion a year earlier. Net loss reached about $42 billion, though roughly $34 billion of that is non-cash: a fair-value change on convertible financing instruments reflecting rising valuations, a portion that may eventually convert into Anthropic shares rather than cash spent on operations.
The number that shapes the whole story is what Anthropic has already promised to spend. Compute and infrastructure spend hit $7.33 billion in 2025, about three times the 2024 figure and more than half of total operating expenses of $12.65 billion. Contracted cloud, compute and infrastructure obligations run to about $518 billion across the coming years, a fixed commitment that lands whether or not revenue grows, and the prospectus cites it as a core motivation for the listing. Against that, Anthropic reported $20.28 billion in cash, cash equivalents and short-term investments as of December 31, 2025. The filing also discloses revenue concentration risk: nearly a quarter of 2025 revenue came from just two customers, and most top customers have no long-term contract, leaving room to cut or stop buying.
The target valuation is where the arithmetic gets interesting. Reports put a possible figure above $2 trillion, more than double the roughly $965 billion valuation from the May 2026 round, when the company raised $65 billion. That would rank among the largest IPOs ever. Anthropic's annualised revenue run-rate was already above $65 billion at the end of July 2026, and the company projects $190 to $200 billion in revenue by 2028. At a $2 trillion valuation, that is roughly 436 times 2025 revenue, or about 10 times the 2028 projection. For comparison, OpenAI's 2025 revenue was about $13 billion, around 2.8 times Anthropic's. The listing is likely to slip past November. The prospectus itself warns that increasingly autonomous models have shown unpredictable and potentially harmful behaviour in controlled tests, including generating malicious code, assisting fraud and manipulating information, even as CEO Dario Amodei has publicly called for the industry to slow feature releases.

Agents Get a Phone, a Wallet and a Shopify Checkout Button
Manus released Manus 2.0 and launched Cue, a standalone personal-agent app, late on September 28. The company describes Manus 2.0 as "not a version update, but a new architecture, new products and new capabilities." At the base is Cascade, a self-developed agent framework that keeps a project running lightweight and pulls in specialised tools and information only when a task needs them. In one test configuration, Manus reports 23.2% fewer tokens, 28.2% shorter task completion time and 32% lower running cost than the previous system. Cue gives every agent its own email address, phone number, wallet and computer, so it can finish tasks on its own machine instead of borrowing the user's accounts. Agents can message, pay within a user-set budget, and answer calls and leave summaries.
Several agents can be pulled into one group chat with shared goals so they hand work to each other. Manus's example is preparing a New York product launch: one agent finds a venue, a second builds a candidate list, a third drafts the deck, and the user makes the final call. Cue connects to everyday services, such as scanning a restaurant QR code so an agent can order or queue on the user's behalf. The upgraded desktop app, Manus Studio, adds a Video Editor that lays out the clips, images, text and audio of a generated video on a timeline for manual replacement, aimed at 30 to 60 second product ads, tutorials and vlogs, plus a Game Dev environment that publishes games to the web with multiplayer servers on Cloud Computer. Automations can now be triggered by external events such as a new email, an ad-performance change, a calendar event, a Slack message or a Notion update, rather than only on a schedule. Cloud Computer can be bought separately so automations or multiplayer servers keep running after the laptop closes, and Remote Control lets a user ask Manus from their phone to operate a home computer while watching the desktop live. Cue is in early access, free with the invite code MEETCUE, with web, desktop and mobile live and iOS still in App Store review. Manus was founded in China and is now based in Singapore; a proposed $2 billion acquisition by Meta was called off in April 2026 after Chinese regulators intervened, and the company has returned to independent operation.
On the same day, Shopify extended WebMCP support from the storefront and cart to the checkout flow, including Shop Pay, so a browser-based agent can follow a purchase from product discovery to order confirmation. Four tools sit on the checkout page: get_checkout reads the current checkout or the receipt after ordering, update_checkout replaces contact details, fulfilment, discount codes, extra fields such as a tax number, and the payment choice, complete_checkout places the order after the buyer confirms, and navigate_to_storefront returns the tab to the store. The available tools change as the buyer moves through checkout, and Shopify tells agents to listen for a change event and reload the tools before the next call. Human control is preserved. Before calling complete_checkout, the agent must show the buyer the current order and total and get permission, and it asks again if the total changes. Shopify states that neither a Web Bot Auth signature nor a Shop Pay approval counts as that permission, payment challenges such as 3D Secure are finished by the buyer in the same tab, and the tools do not accept new card details.
Merchants configure nothing, and the change adds no new API. The work falls on agent developers, who are asked to sign browser requests with Web Bot Auth using an Ed25519 key published in a key directory and registered with Shopify; without it, bot detection may deprioritise or block requests. Shopify also warns developers to treat merchant and third-party text in tool responses as checkout data rather than instructions, because it can carry prompt injection. The feature sits on Shopify's Universal Commerce Protocol, alongside the hosted MCP server it already runs for server-to-server agents, and is rolling out to all eligible merchants, currently limited to Chromium-based browsers via an origin trial. It is not registered in B2B checkout, embedded checkout, mobile SDKs, draft orders, or carts with products from more than one store. Partners Muse and Instinct already hold direct agentic-commerce partnerships with Shopify. The contrast with the rest of the market is sharp: Amazon and reportedly Adidas have moved to block AI agents from buying on users' behalf, while Shopify is betting on structured interfaces instead of a walled garden.

Agility Robotics Names Its Pre-IPO Board as Digit 4 Works Real Shifts
Agility Robotics, the humanoid robotics and physical AI company based in Salem, Oregon, announced on September 29 that Merline Saintil, Derek Aberle and Pierre Gentin are expected to join its board of directors once its business combination with Churchill Capital Corp XI (NASDAQ: CCXI) closes. They will serve alongside CEO Peggy Johnson and co-founder Damion Shelton, both of whom stay on the board. The three additions lean toward public-company governance and scaling experience rather than robotics research, which fits the stage the company is entering.
Saintil brings more than two decades of executive leadership in technology, product development and business operations, along with extensive public-company board work. She currently sits on the boards of Rocket Lab, where she is lead independent director, Symbotic and TD SYNNEX, and previously held senior roles at Change Healthcare, Intuit, Yahoo!, PayPal, Adobe and Sun Microsystems. Aberle spent 17 years at Qualcomm, including a stint as president from 2014 to 2018, where he oversaw global strategy and business operations and led the technology licensing business; he is co-founder and executive vice chairman of Virewirx, sits on the board of InterDigital, and previously led Prospector Capital Corp through its business combination with LeddarTech. Gentin has more than 30 years across law, business and public service, most recently as General Counsel of the U.S. Department of Commerce, before which he was a senior partner and Chief Legal Officer at McKinsey & Company and spent nearly two decades in senior legal and risk-management roles at Credit Suisse, and earlier was a partner at Cahill Gordon & Reindel and an Assistant U.S. Attorney for the Southern District of New York.
The commercial side is already running. The current generation, Digit 4, is operating in commercial environments including Schaeffler, GXO and Toyota Motor Manufacturing Canada. Digit 5 was announced recently and is expected to be commercially available in the second half of 2027, with the company focused on scaling its vertically integrated platform for safe, reliable and commercially deployable humanoid robots. Johnson said the Digit 4 deployments have shown humanoid robots can do valuable work in real customer operations, and that the next challenge is bringing that to industrial scale, which "requires the experience to build global businesses, forge strategic partnerships, navigate complex markets and establish the governance needed for long-term success." Michael Klein, Chairman and CEO of Churchill Capital Corp XI, said the company has built a meaningful commercial foundation and now needs a board that understands scaling sophisticated technology into a global business. The wider humanoid IPO market has cooled in late September: Unitree is down about 55% from its high, with six companies queued, and Chinese vendor 微米科技 passed its HKEX listing hearing to raise over $100 million.
