Claude Fable 5 is Anthropic’s top-tier X-High reasoning SKU at $10/$50 per million tokens on the Claude Platform. That is double Opus 5 output. Choose it for heavy multi-step autonomous tasks, not when you are summarizing tickets. CompareLLM keeps Fable and Opus as separate rows so the invoice does not hide inside a brand name.
When Fable is the wrong buy
If SWE-bench on Sonnet 5 is close enough for your repo and you run thousands of turns a day, Fable’s output line item will dominate the bill. Use the pair page versus Opus 5: coding delta first, then output $/1M. Preference Elo alone will tell you to always pick the crown.
Empirical Evaluation & Architectural Analysis
Empirical evaluations recorded across the CompareLLM Leaderboard highlight how parameter scaling and inference optimization impact production throughput and cost-per-token economics. Reference the interactive scorecard above for verified snapshots or inspect the dedicated claude-fable-5 dossier.
What we refuse to invent
We do not score “soul” or export-control drama. We store dated Elo, SWE-bench, TTFT, and list price. If a cell is missing, the public feed did not match yet.
