Anthropic introduced Claude Fable 5.1 and Claude Mythos 5.1 last week, labeling them as “the world’s most advanced models for coding and knowledge work.”

“Their research capabilities offer an early glimpse of how AI models will contribute to scientific progress,” the San Francisco – based lab hinted.

Claude Fable 5.1 and Claude Mythos 5.1 are the same model, but with different levels of safeguards, specifically designed for cybersecurity and the life sciences.

Fable 5.1 can be used to discover software vulnerabilities—though not to develop exploits for them. In biology, Claude Mythos 5.1 can access advanced biology capabilities.

Claude Fable 5.1 sets a new standard for coding, knowledge work, and long-running problem-solving tasks.
