Anthropic's Fable 5, Mythos 5 caught in Washington export whack-a-mole 🪓

Anthropic has dispatched senior technical staff to Washington to negotiate the reversal of export controls that took its Fable 5 and Mythos 5 models offline for foreign users days after launch, according to a source close to the company and reports from Axios and The Wall Street Journal. The action follows a Friday order barring foreign access to the systems, prompting Anthropic to disable the models for non-U.S. users.

The two sides have been in contact since the order was issued. Anthropic technical staff held virtual meetings with White House officials, with Commerce Secretary Howard Lutnick and Cyber Director Sean Cairncross participating in Saturday's discussions alongside Anthropic co-founder and chief compute officer Tom Brown and policy chief Sarah Heck. A person familiar with the talks said both parties want the models restored, though the form any fix would take remains undefined. Some officials have floated a framework pairing Anthropic engineers with government security researchers as a possible compromise.

The dispute carries stakes that extend beyond AI policy. Anthropic has confidentially filed an S-1 with the Securities and Exchange Commission, preserving optionality on a potential initial public offering, and a protracted standoff with Washington could shape investor sentiment around that debut. BeInCrypto has reached out to the White House and Anthropic for comment.

The model's removal from foreign access came only days after its launch, complicating deployment plans for international users and partners. The outcome of the Washington talks will determine whether the systems return in their original form, under modified terms, or remain restricted.
