Anthropic: Claude Mythos 5

Chat Compare

Claude Mythos 5 is Anthropic's limited-availability Mythos-class model and the direct successor to Claude Mythos Preview. It is the same underlying model as Claude Fable 5, but offered through Project Glasswing and related trusted-access programs with safeguards lifted in specific high-risk domains, making it Anthropic's restricted frontier track for the hardest long-horizon coding, cyber-defense, and research workflows.
