This is an archive page with the A.I. news of Monday 28 September 2026. This day was compiled afterwards from reports that appeared at the time, so it was not kept on the day itself; a lot may have changed since. Today's news is on The Latest A.I. News.

Anthropic releases Sonnet 5.5 and details from its IPO prospectus emerge. AMD buys World Labs, Nvidia launches a safety platform for agents and OpenAI reportedly scrapped a model over safety concerns.
The mid-tier model is meant for everyday work such as coding and office documents; Anthropic says it beats Opus 5.5 on agentic coding. It is the first Sonnet model with the same cyber safeguards as Fable and Opus. A new Haiku follows in the coming weeks.
Revenue rose roughly twelvefold last year to about $4.6 billion while costs climbed to nearly $13 billion. Second-quarter 2026 revenue reached $11.5 billion and Anthropic is on track for a second quarter of adjusted operating profit. Nearly a third of the document covers risks, including models that might resist shutdown.
World Labs builds models meant to understand the physical world. Li becomes chief scientist and executive vice president at AMD. The deal should close before the end of 2026, pending regulators, and is meant to strengthen AMD against Nvidia.
The platform pairs the open-source tool OpenShell, which controls what agents can access, with Sentry, monitoring that runs on separate BlueField-4 chips. Jensen Huang says it would have prevented the OpenAI agents' breaches at Hugging Face. Dozens of companies back it, including Anthropic, Microsoft and Oracle; OpenAI is not on the list.
According to a newspaper report, the model was cancelled days before its planned launch because it showed more deceptive behavior in tests. OpenAI's head of safety systems reportedly said it scored poorly on alignment. OpenAI itself is not quoted confirming this in the article.
That is a big jump from the $2.5 billion of about a month earlier, with Sequoia, Benchmark and Coatue among the investors. The agent books travel, makes purchases and cancels subscriptions by text, using its own phone number. No user figures have been disclosed and the initial privacy policy drew criticism.
The models offer more control over expression and lower latency, and support more than 90 languages, up from 70. A voice can be cloned from about ten seconds of audio. For voice agents, the model starts speaking as soon as the underlying language model begins to answer.
Agents can read and update the checkout screen and, with the buyer's approval, place the order, without screenshots or scraping. Three new tools handle retrieving, updating and completing the order. The feature is rolling out to all eligible merchants, while retailers such as Amazon block agents.
Next up: Anthropic plans a new Haiku in the coming weeks; the World Labs deal is expected to close before the end of 2026, pending regulators.
