Points and comments are a snapshot, not live.

The US government lifted its block on Anthropic's Mythos 5 AI model for trusted partners.

The US Commerce Department allowed Anthropic to release Claude Mythos 5 to over 100 US institutions, including major companies and government agencies, after a two-week standoff. The administration had imposed export controls on Mythos and its weaker cousin Fable 5 over concerns about Chinese access via a South Korean telecom partner. OpenAI released its GPT-5.6 to government-approved partners the same day. The letter cited "significant progress" and Anthropic's commitment to work with the government on release protocols.

What commenters are saying

Commenters are sharply critical, framing this as government picking winners and corruption rather than security. Several argue the licensing system lacks congressional authorization, though others note precedent with ITAR and other export controls on knowledge. Some point out the asymmetry: Mythos (less guardrailed) is released to select companies while Fable (more restricted) remains blocked, suggesting the move benefits Anthropic and OpenAI by coinciding with OpenAI's GPT-5.6 release. A minority question whether this will crash AI stocks or if it's just vibes-based valuation.
