Anthropic has launched Claude Fable 5, a new model positioned as safe for broad public access, with safeguards designed to route sensitive queries to a more restricted model, Claude Opus 4.8. The company claims these safeguards trigger in less than 5% of sessions, allowing most users to experience Fable 5 directly. However, Anthropic acknowledges that adversaries will attempt to circumvent these safety measures, making the model's security and its ability to detect and fix failures a key aspect of its evaluation.
