The Trump administration is expected to allow the resumption of access to Anthropic's high-performance AI model Claude Fable 5, with restrictions possibly lifted as early as early July 2026. The model was suspended on June 12 following U.S. government export control instructions over concerns about jailbreaking and misuse in cybersecurity. The Department of Commerce has already allowed Mythos 5 to return for trusted cyber defenders, and discussions on Fable 5 are ongoing, though final approval from the Department of Defense and NSA is still needed.
Anthropic's Claude Fable 5, a high-performance AI model released on June 9, 2026, was suspended on June 12 after the U.S. government ordered export controls over concerns that its capabilities in cybersecurity and biology could be jailbroken by attackers. The model, which outperformed Claude Opus 4.8, GPT-5.5, and Gemini 3.1 Pro in benchmarks, is designed for long-duration autonomous tasks and coding. On June 27, the Department of Commerce allowed Mythos 5, which shares the same base model, to resume for trusted cyber defense organizations. Commerce Secretary Howard Lutnick said Anthropic had made progress on risks, and discussions on Fable 5 continue. Axios reported the administration is moving toward lifting restrictions, possibly as early as this week, but final approval from the Department of Defense and NSA is required, and conditions like pricing and identity verification remain unclear.
