Anthropic‘s Fable 5 model could return within days as the Trump administration prepares to lift restrictions on the artificial intelligence system. A source familiar with the situation says the Commerce Department is close to approving the release after Secretary Howard Lutnick told the company it had addressed government concerns. The Pentagon and National Security Agency still need to sign off on the final clearance. Fable 5 was shut down on 12 June on orders from the US government over safety worries. Mythos 5, a variant without added safety restrictions that Anthropic also had to take offline, is already back for select partners.
The immediate resumption of Fable 5 highlights the ongoing tension between commercial deployment and regulatory oversight. Both Anthropic and OpenAI are now pushing for a legally defined review process for new AI models instead of case-by-case decisions. Whether Fable 5 will face ongoing restrictions after release, similar to GPT-5.6 Sol, or become available worldwide right away remains unclear. OpenAI does not expect full clearance for its own model until the coming weeks.
* Mythos 5 is already operational for select partners
* The Pentagon and NSA must still approve the release
* Companies seek a fixed legal review process
