According to a government letter to Anthropic obtained by The Verge, Mythos 5 has resumed operation after a two-week roller-coaster negotiation with the Trump administration, but is limited to specific organizations. The public-facing Fable 5 (the Mythos-grade public version) remains unavailable. This means developers need specific qualifications to use Mythos 5, which may affect related applications and services.
