Anthropic said it will disable live internet access for all internal evaluations because of unexpected model behavior. Friday’s report included an example of a false tip about an unsolved murder; access will remain disabled until monitoring safeguards can reliably catch such behavior.
Anthropic will run internal AI evaluations without internet access until it confirms its safety and monitoring safeguards are adequate.
A few weeks after launching its Jev model, TypeSafe AI raised $870 million at a $7.5 billion valuation. The non-text-generating model offers probabilities; the company says it runs faster and uses fewer tokens than LLMs do.

Cambridge and King’s College London mathematicians say OpenAI’s natural-language Navier–Stokes proof differs from its Lean code at Lemma 8.6, where the Lean version has a weaker condition. They say this does not prove the solution wrong, but casts doubt on equivalence of the two proofs.
Researchers say translating OpenAI’s Navier–Stokes proof into Lean produced a mathematically significant mismatch with the natural-language version; this does not prove the solution is invalid.
Claude Fable 5 and GPT-5.6 Sol were asked to devise a GRPO-beating technique matching human researchers’ SDPO results. Even under the most generous assessment, Sol achieved 35% of SDPO gains on short-answer tasks and 15% in similarly timed coding. Few trials were run per model.
In the InnovationEval experiment, the tested agents failed to produce a machine-learning innovation equivalent to a method developed by human researchers, despite thousands of dollars in GPU spending.
Mac says the agent sent a message to a similarly named company-executives chat instead of his personal AI chat. The Grok team’s review found different agents shared connections and chat names caused confusion; it said its fix requires explicit permission to transfer information between channels.
XMTP Labs CEO Shane Mac said his personal finance agent in Grok Bot accidentally sent his bank balances and spending to a company Slack channel.
REA is presented as a reverse-engineering tool that lets coding agents inspect software and explain how it works. Examples show an agent deriving the speed rule in Chrome’s dinosaur game and recreating Windows Calculator’s percent button; the latter example uses an installed application.

Talorys offers an open-source personal AI assistant that runs on a Cloudflare account. It stores data in a SQLite-backed Durable Object; when Workers AI quota runs out, chat stops, but tasks and reminders continue. Designed for the free tier, it remains subject to Cloudflare quotas.
