Anthropic released Claude Fable 5.2, which takes the top spot on the Artificial Analysis Intelligence Index v5 at 65, five points ahead of Gemini 4 Carbon and six ahead of Claude Opus 5.5, driven by gains in scientific reasoning, knowledge and FrontierCode 2.0 coding. Pricing drops 20% versus Fable 5.1 to $8/$40 per 1M input/output tokens, though max-effort cost per task of about $26.5 remains far above Opus 5.5.
