Anthropic disclosed to the US Senate that operators affiliated with Alibaba ran 28.8 million exchanges against Claude through 25,000 fraudulent accounts over six weeks — the largest known distillation attack against Anthropic. The numbers are real; the framing is lobbying.
The US government banned Anthropic's Fable 5 and Mythos 5 globally after a narrow jailbreak was found that could unlock Mythos's autonomous offensive cybersecurity capabilities. Anthropic disputes the decision as disproportionate. The real issue is harder than either side is saying: you can't export-control your way out of a model that already knows how to hack.
arXiv began enforcing a new policy this week: submit a paper with AI-hallucinated citations and you're banned from the platform for a year, after which future preprints require peer-review acceptance before posting. With fabricated citations rising tenfold since 2023 — now appearing in 1 in 277 papers — arXiv's response is to repurpose the peer-review gate that most researchers treat as optional into a punitive instrument.
Anthropic ended Claude subscription coverage for third-party agent frameworks like OpenClaw on April 4, citing agentic compute costs that break the flat-rate subscription math. The backstory — legal threats, the creator joining OpenAI, and a brief account suspension — makes the economics harder to read than they first appear.
