Why did the Trump administration order the models offline?

The June 12th export control order cited security concerns and banned access by any foreign national to Mythos 5 and Fable 5. The order was reportedly triggered after Amazon CEO Andy Jassy flagged a method for seemingly breaking Fable 5's guardrails that prevent it from finding exploitable security holes.

Why hasn't this been resolved in two weeks?

There is no clear framework for applying export controls to AI systems like there is for traditional dual-use manufacturing products. The process normally unfolds over months or years, but was compressed into a few days in this case, leaving both sides trying to figure out how to apply the rules from first principles.

What does this mean for other US AI companies?

OpenAI, Google, and Microsoft have models that may pose similar risks to Mythos, and the Trump administration reportedly asked OpenAI to delay the release of GPT-5.6 over security concerns. The situation has created a power vacuum in the global AI market and prompted countries to call for non-American AI alternatives.

Anthropic's Mythos models still offline after 2 weeks of talks with Trump administration

Send on LINE

Key takeaway

Anthropic's Mythos-class AI models have been offline for two weeks after a Trump administration export control order, with no resolution in sight despite intense negotiations.
The shutdown threatens Anthropic's path to profitability and upcoming IPO, while signaling to other US AI companies and foreign governments that America is willing to restrict access to its most powerful AI systems on security grounds.

3 Key Points

What happened
Anthropic took its Mythos-class and Fable 5 models offline following a June 12th Trump administration export control order banning access by any foreign national due to security concerns. Two weeks of high-intensity negotiations have produced no resolution, and the company says there is no news to share.
Why it matters
Mythos models were supposed to boost Anthropic's revenue ahead of an IPO, with input tokens priced at double the cost of lower-powered alternatives. The prolonged shutdown also signals the US government is willing to lock down American AI systems it deems risky, creating uncertainty for other companies like OpenAI, Google, and Microsoft—and potentially opening space for non-American AI systems globally.
What to watch
The impasse stems partly from a lack of clear framework for applying export controls to AI systems, and a reported vulnerability in Fable 5 (flagged by Amazon CEO Andy Jassy) that some cybersecurity experts say was overblown. Anthropic cofounder Tom Brown and public policy chief Sarah Heck are now leading talks, but progress remains unclear.
