Who is Claude Fable 5 for?
Claude Fable 5 is Anthropic's premium adaptive-reasoning model — the one-shot king until Fable 5.1 arrived. At $10 / $50 per 1M it's among the most expensive models we track — but practitioners consistently called it the best model in the world for vibe coding because it nails tasks on the first pass.
In practice it's a subscription tool more than an API tool: hitting it via the API is rarely worth the per-token bill. If you want first-try quality and your budget allows the premium, it's the strongest single model for one-shot product work.
