Negotiations between Trump administration officials and Anthropic concluded Monday without lifting export controls on the company’s two most powerful AI models, Wired reported, leaving the path forward unclear.
Commerce Secretary Howard Lutnick sent Anthropic CEO Dario Amodei a letter on June 13 imposing export controls on Fable 5 and Mythos 5, banning any foreign national — including Anthropic’s own foreign national employees — from accessing the models anywhere in the world. The letter cited national security concerns but provided no specific rationale. Anthropic disabled both models for all users that evening to comply.

An unnamed company told the administration it could jailbreak Fable 5 to access Mythos-level capabilities. Officials tried to get Anthropic to pause the release — Anthropic says it was never told why — and sent the export control letter when those efforts failed.
Anthropic reviewed the technique and concluded it involves asking the model to read a codebase and identify software flaws — a capability also present in other publicly available models, including OpenAI‘s GPT-5.5, and one used routinely by cybersecurity defenders.
“We disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people,” the company said in a statement.
Monday’s talks involved the Commerce Department’s CAISI and ONCD units. Lutnick dialled in from the G7 summit in France. National Cyber Director Sean Cairncross did not personally attend. Commerce has expressed willingness to restore Fable 5 for consumer use if Anthropic resolves the jailbreak concerns — but the two sides remain apart on whether those concerns are valid.
Anthropic released Fable 5 on June 9, describing it as “Mythos-class” — a new capability tier the company said exceeded any model it had previously made publicly available.
