Initial impressions of Claude Fable 5 (12 minute read)
Anthropic claims that Claude Fable 5 offers the same performance as Mythos 5 but with stricter guardrails. It has a 1 million token context window with 128,000 maximum output tokens.

The Claude API has new mechanisms for alerting users when these guardrails are activated, and there is an option to request to fall back to another model automatically if something gets rejected.
