Claude Fable 5 is amazing. The most capable AI model available to the public. It sits above the Opus class, in a new tier Anthropic calls "Mythos-class," meaning models whose capabilities are powerful enough to require a new category of safety measures before general release.
Think of Mythos-class as the tier where the model is capable of completing weeks of real work autonomously: not faster answers, but entirely different kinds of tasks that weren't possible to hand off before.
The biggest performance gains show up on long, multi-step work, not quick one-offs. Fable 5 has built-in classifiers that monitor every request. A classifier is a separate AI system that runs in parallel with the main model, monitoring your requests and deciding whether a request falls into a category that requires extra caution.
