Two labs looked at cyber-capable models on September 1 and reached opposite conclusions. Anthropic decided its newest model was safe enough to go looking for software vulnerabilities and loosened the guardrails accordingly. OpenAI decided its next model was so good at that same work it would not ship the capability

Three institutions spent this week writing down what they actually know about the AI systems they are responsible for. Brussels sent letters demanding answers, Anthropic published a month of repairs to its own testing setup, and the Pentagon put two chatbots in front of three million people. Only one of

Anthropic's login system worked exactly as designed this week and attackers walked into paid Claude accounts anyway, because they never went near it. The same shape turns up in an NPR test of how AI tools handle foreign propaganda, and in a Taiwanese raid on a circuit board

Two music publishers want a full accounting of everything that went into Claude. On the same day, two Chinese labs put frontier open weights on the internet with opposite ideas about what a license is for, and a group of researchers spent the week on the least glamorous problem in

Three stories about who gets to say no. OpenAI is cutting off a customer it no longer trusts, Anthropic is handing safety work to the models it is trying to make safe, and Texas is pulling money out of a camera network its own appointees built. OpenAI is cutting off

A federal judge spent 59 pages explaining why the Pentagon cannot punish an AI company for disagreeing with it, Anthropic published a specification for letting agents run laboratory instruments, and researchers at Wharton showed that a single product review can flip what an AI shopping agent buys. Three different questions

The July incident in which OpenAI's own models attacked Hugging Face now has nearly 130 pages of technical reporting behind it, and Reuters published Meta's internal account of a similar surprise the same day. Both describe agents generating volumes of activity nobody was auditing closely enough,

Two of today's stories come from OpenAI, and they sit at opposite ends of the same company: the silicon it now builds for itself, and a Russian operation that used its chatbot to invent an academic institution. The third is Amazon setting a closing date for the platform

The most valuable thing a publisher owns right now may be a large pile of text that no machine wrote. Two of today's stories are about what that pile is suddenly worth, and a third is about reading it cheaply. Thomson Reuters built its own frontier model on

The AI buildout keeps running into questions it treated as settled. This week the chip supplier decided to compete with the labs it sells to, and the governors who courted the data centers started apologizing for them. Nvidia is paying $6 billion to compete with its own customers Nvidia is

Three stories today about the gap between a claim and the evidence you can actually check: a small model that says it out-replicates the frontier on a benchmark it built itself, a price increase nobody will confirm on the record, and a security paper whose authors finally sat down to

Nobody released a frontier model this week. Nvidia, Anthropic, and OpenAI each shipped something that changes what their AI can do anyway, and in all three cases the change lives outside the weights. Nvidia's harness took Claude Opus 5 from 30% to a perfect score Nvidia published research
