The Department of Commerce has removed export restrictions on Anthropic's Claude Fable 5 and Mythos 5 models, less than three weeks after ordering the company to suspend foreign access due to national security concerns.
Anthropic announced Tuesday that the US commerce department lifted export controls on its advanced AI models. The company said it would begin restoring access to international users starting Wednesday.
The swift reversal follows an earlier order that forced Anthropic to immediately suspend access to Fable 5 and Mythos 5 for all foreign nationals. The restriction came amid government concerns about potential national security risks posed by the models' capabilities.
The company did not disclose details about what prompted the commerce department's decision to remove the controls. Anthropic's statement on X simply confirmed that access restoration would commence the following day.
This marks a significant shift in US policy on advanced AI exports. The brief restriction period suggests either that initial security assessments were revised or that alternative safeguards were implemented to address government concerns while allowing broader access.
Anthropics two flagship models—Fable 5 and Mythos 5—represent the company's most advanced AI systems. The temporary suspension affected researchers, developers, and users outside the United States who had been working with these models.
The incident highlights ongoing tensions between AI innovation and national security considerations. US regulators continue evaluating how to balance advancing domestic AI capabilities with controlling sensitive technology access.
Anthropic has not released statements about specific changes or conditions associated with the lifted restrictions. The company's focus remains on resuming service to affected international users.
