Five Eyes warns of AI cyberattack capability as OpenAI ships a security-tuned model

An intelligence alliance and a frontier AI lab acted on the same question on the same day. One warned of offensive AI. The other lowered the refusal rate for security work.

US export directive cuts off Fable 5 and Mythos 5, hardening model access as a controlled good

Anthropic confirmed a government order to suspend all access to two of its models, the clearest sign yet that the government now treats frontier model weights as controlled military goods.
