The US Commerce Department has lifted export controls on Anthropic's Claude Fable 5 and Mythos 5 AI models after the startup worked through the Trump administration's safety concerns. The move unblocks global access starting this week and signals the administration's willingness to ease restrictions that had raised concerns about export controls becoming a broader regulatory tool for frontier AI models.

The US Commerce Department has lifted export controls on Anthropic's Claude Fable 5 and Mythos 5 models that had been imposed on June 12, requiring US approval before foreign nationals could access them. Fable 5 access is beginning to return globally starting Wednesday across Anthropic's platforms, with availability through Amazon, Microsoft, and Alphabet cloud services expected to follow as quickly as possible.
Why it matters
The restrictions had forced Anthropic to disable the models while negotiating with officials over safety concerns. The reversal could ease pressure across the AI sector, as the controls had raised questions about whether export restrictions might become a broader tool for regulating frontier model access. Anthropic, valued at $965 billion（約150兆円） after its latest funding round and already filed confidentially for an IPO, said it plans to work with Washington on future protocols and standards that could shape broader industry rules.
What to watch
Anthropic is redeploying Fable 5 with new classifiers aimed at blocking more cybersecurity tasks, while Mythos 5 access has already been restored for some US organizations tied to Project Glasswing.
