According to a letter from Commerce Secretary Howard Lutnick seen by Reuters, the export controls were withdrawn as Anthropic agreed to proactively detect and address security risks associated with the models, work closely with the U.S. government on protocols for future releases, and inform authorities of any malicious activity.
The restrictions were initially imposed following concerns about potential 'jailbreak' vulnerabilities that could allow users to bypass safety measures in the AI models. The U.S. has been increasing oversight of new AI model releases amid fears that advanced AI technologies could be misused by military intelligence agencies in countries like China and Russia.
The export controls had drawn criticism from industry figures, including OpenAI CEO Sam Altman who expressed reservations about government involvement in selecting customers for advanced AI models. OpenAI also delayed the full public launch of GPT-5.6 at the U.S. government's request, limiting access to a small group of vetted partners.
Anthropic said late on Tuesday that it would begin restoring access to Claude Fable 5 and Mythos 5 from Wednesday, after the US Department of Commerce notified the company that it had removed its export controls. In a statement posted on X, Anthropic expressed gratitude to users for their patience.
Francesco Bailo, deputy director of the AI, Trust and Governance Centre at the University of Sydney, suggested that reports about 'jailbreak' vulnerabilities in Fable 5 were widely inflated beyond their actual significance. He noted that the U.S. government likely realized it had overreacted and that blocking these models could set a dangerous precedent for future regulations.
