Claude Fable 5.2 Tops Artificial Analysis Intelligence Index with 65

On November 10, Artificial Analysis launched an evaluation page for Anthropic's Claude Fable 5.2 and updated its Intelligence Index leaderboard: the model scored 65 on Intelligence Index v5, ranking first among all 117 models, clearly ahead of second-place Gemini 4 Carbon (60) and Claude Opus 5.5 (59). X users @Angaisb, @haider1, and several Reddit users reshared screenshots of the leaderboard, and the results spread quickly through the community.

Confirmed

• The leaderboard is Intelligence Index v5.0.1, comprising 9 evaluations; Reddit user @AbbreviationsBest858 posted the full ranking, which includes benchmarks such as AA-Briefcase v1.1, AutomationBench-AA, and Terminal-Bench
• The next-ranked models are Gemini 4 Carbon (60) and Claude Opus 5.5 (59), an order confirmed by screenshots from Reddit users @likeastar20 and @haider1; GPT-6 series models are also on the list but with lower scores

Why it matters

• The Intelligence Index is a widely cited community benchmark for overall model capability; Fable 5.2 taking the top spot by a clear margin means Anthropic's lead in the latest round of model competition is now backed by third-party evaluation
• The leaderboard also shows the relative positions of leading models such as Gemini 4 Carbon, Claude Opus 5.5, and GPT-6, offering a reference for the current frontier-model landscape
