how good is Claude Fable 5 at coding?

Claude Fable 5 sits at #2 of 13 ranked models, posting 95.0% on SWE-bench Verified — 1.2 points behind #1 GPT-5.6 Sol. On the harder SWE-bench Pro it scores 80.3%.

Score provenance: Independent (vals.ai, Jul 14 2026, mini-swe-agent bash-only harness): SWE-bench Verified 95.00% ±0.98. Held the top score until GPT-5.6 Sol was evaluated at 96.20% ±0.86 on the same harness — a 1.2-point gap that is inside the combined margin of error (~0.9 sigma), so the two are a statistical tie and we rank Sol first only because it scored higher. SWE-bench Pro 80.3% uses Anthropic's own scaffolding and is contested. Restored Jul 1, 2026 after a 20-day export-control suspension. Pricing $10/$50 per 1M.

what does Claude Fable 5 cost?

$10 per 1M input tokens and $50 per 1M output — #13 cheapest of the 13 models we track. Coding workloads are output-heavy, so weight the output rate when budgeting. Run your own volume through the AI API cost calculator for a monthly estimate.
