  • Community-driven innovation and rapid availability of cutting-edge models.
  • Standard Azure AI integration, with support and maintenance managed by the respective providers.

Models from Partners and Community are deployable as Managed Compute or serverless API deployment options. The model provider selects how the models are deployable.

About this model

Claude Mythos 5.1 is Anthropic's most capable model for cybersecurity and biology research. It is best-in-class at cyberdefense, including vulnerability discovery, attack-surface auditing, red teaming, and threat intelligence, and it is Anthropic's strongest model for biology research. Anthropic currently only provides access to a small, but growing, set of customers through its trusted access programs.

Key model capabilities

  • Cybersecurity Claude Mythos 5.1 is Anthropic's most capable model for cybersecurity, helping security teams with defense and authorized testing, including threat intelligence, vulnerability discovery, penetration testing, red teaming, and reverse engineering. Since security work is inherently dual-use, access is currently limited.
  • Biology and life sciences: Claude Mythos 5.1 is Anthropic's most capable model for life sciences, helping researchers with drug discovery and molecular design, target and disease biology, preclinical and translational research, biodefense screening, and scientific diligence. Since biology research is inherently dual-use, access is currently limited.
