The Department of Commerce has lifted the export controls that suspended access to Claude Mythos 5 and Fable 5, with Anthropic confirming it will begin restoring Fable access on July 1. The reversal comes just 18 days after the US government directive that suspended both models on June 12 — one of the fastest federal AI policy reversals of 2026, and it lands in the same 72-hour window as Anthropic's Claude Sonnet 5 launch and its new Claude Science research workbench.
This is the third major swing in Anthropic’s federal relationship inside two weeks: the Pentagon called Anthropic a “supply-chain risk” and steered a DoD AI contract to OpenAI (June 29), while Gov. Newsom simultaneously struck a 50%-discount Claude deal for California state agencies (June 29). Commerce restoring Mythos/Fable access suggests the federal posture toward Anthropic is fragmented across agencies rather than uniformly hostile.
