- Trump administration disabled Anthropic's Fable 5 and Mythos 5 models with less than 90 minutes of notice, per the NYT, leaving workers 'puzzled and increasingly concerned'
- Anthropic staff are wondering whether the administration is bullying the startup, with internal chat messages leaked to the NYT showing the same researchers who previously warned of a cybersecurity 'reckoning' now feeling 'picked on'
- Trump administration refused G7 countries' requests to regain access to Mythos 5, calling it 'completely illogical'; the UK requested a 'carve-out' from the ban (NY Post sources)
- Dario Amodei (Anthropic), Sam Altman (OpenAI), and Demis Hassabis (Google) jointly called for US-led collaboration on AI rules at the G7 summit in Evian, France — an unusual cross-company alignment
- Macron and Modi raised concerns over the US block on Mythos at the G7, with Macron seeking a workaround and Trump declaring 'I'm the boss' at the summit
- Trump told the WSJ that negotiations with Anthropic are 'going fine' even as the AI model shutdown drags on
Why it matters: The administration disabled two of Anthropic's models with under 90 minutes' notice and is refusing G7 allies access, forcing rival AI CEOs Amodei, Altman, and Hassabis into a rare joint statement at the G7. With the UK requesting a carve-out and Macron seeking a workaround, the dispute is now a diplomatic flashpoint over frontier AI access.
