About this release

What is Mythos 5.2?

Claude Mythos 5.2 shares the exact underlying model and specs as Fable 5.2 (1M context, $8/$40 pricing, faster generation) but is available only to organizations verified through Anthropic’s Cyber Verification and Life Sciences programs. It retains fuller capabilities for cybersecurity and biology research.
