Tag: Claude Mythos

Claude Mythos is Anthropic’s most powerful — and most restricted — model. Sitting above Opus in capability, it scored 93.9% on SWE-bench and 97.6% on USAMO math benchmarks. Its advanced cybersecurity capabilities, including autonomous zero-day vulnerability discovery, make it too powerful for open access. Available only to vetted partners via Project Glasswing. Best for: frontier-level cybersecurity research, advanced autonomous reasoning, and tasks where Opus simply isn’t enough.
