Claude Fable 5 is the most intelligent generally available model in the current field: its production configuration leads the independent Artificial Analysis Intelligence Index, while Anthropic reports 80.0% on SWE-Bench Pro and 84.3% on Terminal-Bench 2.1. Buy it selectively, not by default. At $10 per million input tokens and $50 per million output tokens, it is the most expensive model in the current PickAI roster, and its published input and output token-per-minute limits are only one quarter of Opus 4.x and Sonnet 5. Fable can also decline classifier-flagged requests involving cybersecurity, biology or chemistry, model distillation, or frontier-AI development; supported Claude clients may then serve the request with Opus 4.8. Anthropic says client users are notified and API responses identify the serving model or refusal, so production integrations should surface that metadata and never assume every Fable request was answered by Fable.
