Anthropic Releases Claude Fable 5 to General Public

Anthropic has launched two new AI models, Claude Fable 5 and Claude Mythos 5. Fable 5 is now broadly available to users and developers, surpassing all previous generally available Claude models in software engineering, knowledge work, vision, scientific research, and long-running tasks. The release marks the first time Anthropic has brought its powerful Mythos-class capabilities to the public, previously restricted to organizations in its Project Glasswing cybersecurity program. Claude Mythos 5 offers fewer capability restrictions but remains limited in availability.
