United StatesFable and Mythos 5.2 are the same model.
Only organisations approved for cybersecurity or life-sciences research get Mythos, while Fable is open to everyone.
Anthropic says Fable adds cybersecurity and biology safeguards, and both models cost $8 per million input tokens, down from $10.
Anthropic’s claims, including formalising Fermat’s Last Theorem’s proof in 30 hours, come from its own prerelease testing.
Anthropic could begin pitching its share sale to investors as soon as 11 November.
