Anthropic Races to Reverse Fable 5, Mythos 5 Export Controls

Anthropic has reportedly sent senior technical staff to Washington to meet White House officials and undo export controls that took its most powerful AI models, Fable 5 and Mythos 5, offline days after launch.

The trip comes amid a turbulent week that began with a Friday order barring foreign access to the models, forcing Anthropic to disable them for foreign nationals.

The two sides have talked since Friday’s order. Anthropic technical staff have held virtual meetings with White House officials, a source close to the company told Axios.

The Wall Street Journal reported that Commerce Secretary Howard Lutnick and Cyber Director Sean Cairncross joined Saturday’s discussions. Anthropic co-founder and chief compute officer Tom Brown took part, alongside policy chief Sarah Heck.

Both parties want the models back online, though it is not clear yet what a fix would look like. Some officials view the pairing of Anthropic engineers with government security researchers as an early path toward compromise.

The standoff carries weight beyond AI policy. Anthropic has confidentially filed a confidential S-1 with the SEC, giving the company the flexibility to proceed with an IPO. A prolonged fight with Washington could shape how investors read that debut.
