French President Emmanuel Macron addressed G7 leaders and top AI executives, […]
The pullback of Anthropic’s next-gen model marks the moment frontier AI moved from technical promise to political and operational reality.
Anthropic still can’t distribute Claude Mythos or Fable 5 after running afoul of the Trump administration. But no one can say exactly what the company did wrong.
