The US government has lifted its block on Anthropic's advanced Claude Mythos 5 AI model, permitting the company to grant access to over 100 US organizations including major corporations and government agencies, according to multiple reports. The decision follows two weeks of negotiations between the Trump administration and the AI lab, marking a partial de-escalation in tensions that began with export controls imposed earlier this month. Commerce Secretary Howard Lutnick informed Anthropic in a letter that the move was made because "appropriate safeguards are in place," as Wired reported. The letter, addressed to Anthropic co-founder Tom Brown, confirmed that the model can now be deployed to a select group of trusted entities. According to NBC News, the authorization covers approximately 100 trusted organizations, including both government agencies and private companies. "appropriate safeguards are in place." The block was originally imposed after warnings from Amazon and other companies, Semafor reported, leading to a shutdown of both Mythos 5 and its public-facing cousin Fable 5. The Verge noted the rollercoaster negotiation process, noting that Fable 5 remains in limbo with no clear timeline for rollout, while Mythos 5 has been reinstated for select groups. "the public-facing version, Fable 5, remains in limbo with no clear timeline for rollout." Anthropic's restricted release now includes confidence in the safety guardrails implemented for the model's limited use, according to NBC News. The partial resolution allows the AI lab to resume serving institutional clients while broader public access through Fable 5 remains on hold indefinitely, highlighting the ongoing tension between rapid AI advancement and government oversight.
