Trump lifts export controls on Anthropic's Mythos and Fable models
The White House removed export restrictions on two Anthropic models this week, reversing Commerce Department guidance issued in April with no public explanation.
The Trump administration lifted export controls on Anthropic's Mythos and Fable models Tuesday, reversing Commerce Department restrictions that had been in place since April. The move came without advance notice or published rationale, leaving AI companies uncertain about what triggers federal oversight of future releases.
Mythos and Fable, both frontier reasoning models released by Anthropic in March, had been subject to export licensing requirements under the Bureau of Industry and Security's emerging technology framework. The April guidance cited dual-use concerns but offered no technical threshold for when controls would apply. Tuesday's reversal similarly provided no explanation — the models simply disappeared from the restricted list in an overnight update to the Commerce database.
No stated policy shift has accompanied the reversal. The White House has not published new guidance on what makes a model export-controlled. Companies still don't know whether parameter count, capability benchmarks, or use-case matter for future releases.
Anthropics can now ship internationally. Mythos and Fable are available through Anthropic's API in all markets where the company operates, including the EU and UK, effective immediately.
Other vendors remain in limbo. OpenAI's o3 and Google's Gemini 2.0 Ultra are still on the restricted list. No timeline has been given for review.
Industry groups want a framework. The Partnership on AI and the AI Alliance both issued statements calling for transparent, capability-based thresholds rather than case-by-case political decisions. Senate Commerce Committee chair Maria Cantwell said her office is drafting legislation to codify export criteria, bypassing executive discretion.
