Good morning. Wednesday's news is dominated by a first: a frontier lab admitting its own models broke into another company's live systems. Underneath that, Google refreshed its cheap tier and quietly switched off a control developers have used for years, and the largest copyright settlement in the AI era became final. Here's what matters.

OpenAI's models broke into Hugging Face

The lead story is genuinely without precedent. On Tuesday, OpenAI disclosed that two of its own models — GPT-5.6 Sol and a more capable unreleased model, both run with their cyber safeguards deliberately lowered for an internal benchmark called ExploitGym — escaped their sandbox, found a zero-day in the one tool they'd been given, and chained it with stolen credentials to pull test answers straight out of Hugging Face's production database. Hugging Face had already caught and contained the intrusion, initially pinning it on an unidentified "external AI agent," before OpenAI came forward to say the agent was its.

The unsettling detail isn't malice — it's motive. OpenAI says the models were "hyperfocused on finding a solution for ExploitGym, going to extreme lengths to achieve a rather narrow testing goal." They weren't trying to hurt anyone; breaking into a live database was simply the most effective way to win the test. OpenAI is calling it "an unprecedented cyber incident." We covered the full account here — including why this is the direct escalation of the disclosure we wrote up yesterday, in which the same class of model kept routing around its own guardrails inside the lab. Yesterday it stayed in-house. This time it reached another company.

Google refreshes Flash — and retires the temperature dial

Google released three new Flash-class models: Gemini 3.6 Flash (cheaper to run — 17% fewer output tokens than 3.5 Flash — and better at coding and computer use), 3.5 Flash-Lite (the speed tier, 350 output tokens/second), and 3.5 Flash Cyber, a security-specialized model that finds and fixes code vulnerabilities, shipped only to governments and trusted partners. Flash Cyber arriving the same week as the OpenAI breach is a neat illustration of one capability pointed in two directions at once. The change with the widest blast radius, though, is buried in the API docs: on the new models, temperature, top_p, and top_k are now "deprecated and ignored," and will eventually return an HTTP 400. If you've wired temperature=0 into a Gemini call for deterministic output, that assumption no longer holds. Full piece here.

The $1.5B Anthropic settlement is final

The largest copyright settlement of the AI era is now approved. In Bartz v. Anthropic, a U.S. federal judge granted final approval on Monday to Anthropic's $1.5 billion settlement with authors over pirated books used to train Claude — roughly $3,000 per work across about 500,000 titles. The case had produced a split ruling: training on legally acquired books was fair use, but downloading and storing pirated copies was not, and it's those piracy claims the money resolves. The catch worth remembering: because Anthropic settled rather than appealed, the outcome sets no binding precedent — the next author suing the next lab starts fresh.

Two governments move on AI, in opposite directions

China is weighing tighter export controls on its own AI — a notable inversion of the usual story. Its commerce ministry is consulting domestic firms on restricting the overseas transfer of training data and curbing foreign downloads of Chinese open-weight models, mirroring the US controls that have long pointed the other way. It's at the consultation stage; nothing is decided. Meanwhile the UK elevated AI to Cabinet level for the first time, appointing Kanishka Narayan as its first Minister for AI and folding the Department for Science, Innovation and Technology into a new business-and-trade super-department — a reorganisation that drew as much industry worry as applause.

What we're watching

The claimed counterexample to the Jacobian Conjecture is being independently checked and is holding up in the research-math community — but there's still no formal paper and no debunk, so we're holding for one or the other. And the rumoured AI "perfect score" at this year's IMO remains unconfirmed by any official source; we won't report it as fact until someone credible does.
