US reverses export restrictions on Anthropic’s Fable 5, Mythos 5 AI models

The US government reversed export restrictions on Anthropic's Fable 5 and Mythos 5 AI models on June 30, allowing global access to resume after a three-week ban triggered by cybersecurity concerns. Commerce Secretary Howard Lutnick said the administration had worked closely with Anthropic to analyze the models before lifting controls. The decision reflects a broader shift toward "negotiated oversight" of frontier AI models, with developers like OpenAI also coordinating launches with US authorities before expanding availability.
