The US government has granted Anthropic permission to make its latest AI model, Mythos, available to select US government agencies for detecting software vulnerabilities, following earlier restrictions that led the company to withdraw the consumer version Fable globally. Anthropic had pulled Fable after the government barred access outside the US and for non-Americans, citing difficulty in verifying customer nationalities; the company now says it continues to work with the government to restore Fable’s availability.
