Anthropic's Mythos 5 AI Model Gets Green Light for US Institutions After Two-Week Standoff

The US government has lifted its block on Anthropic's powerful Claude Mythos 5 AI model, clearing the way for the company to grant access to more than 100 US organizations including major corporations and government agencies, according to reports from Semafor and Wired. The decision marks a de-escalation in tensions between the Trump Administration and Anthropic, following export controls imposed two weeks ago that shut down the model and its cousin Fable 5 after warnings from Amazon and other companies. Commerce Secretary Howard Lutnick informed Anthropic in a letter that the move was made because "appropriate safeguards are in place," as reported by Wired, which had access to the letter. The reversal followed weeks of discussions between the White House and the AI lab, with Axios noting that Lutnick acknowledged "significant progress" from the company's engagement with the government. The abrupt removal of the models on June 12 had created uncertainty in the industry and among allies whose cyber capabilities were impacted. "appropriate safeguards are in place." The Verge characterized the process as a rollercoaster negotiation, revealing that while Mythos 5 has been reinstated for select organizations, the public-facing version remains unavailable. "The public-facing version, Fable 5, remains in limbo with no clear timeline for rollout," The Verge reported, citing a letter from Commerce Secretary Lutnick to Anthropic co-founder Tom Brown. That means the partial resolution leaves a key product in an uncertain status, even as institutional users regain access. "The public-facing version, Fable 5, remains in limbo with no clear timeline for rollout." Axios reported that the Commerce Department approved a limited return of both Mythos and Fable after the company addressed risks, though The Verge's account suggests Fable's public release is still stalled. The distinction highlights the targeted nature of the easing: institutional access has been restored under conditions deemed acceptable, while broader consumer availability remains under review. The agreement signals that Anthropic has satisfied the government's immediate safety concerns, but full commercial deployment of its cutting-edge models is not yet a done deal.
