Claude Opus 5 has demonstrated outstanding performance in recently surfaced third-party benchmark leaderboards, claiming the top spot as the new global SOTA (State-of-the-Art) model. It has outperformed competitors such as Claude Fable 5 in evaluations by Artificial Analysis and BenchmarkList, drawing significant community attention.

Confirmed

According to the updated Artificial Analysis leaderboard, Claude Opus 5 scored 61 on the Intelligence Index, ranking first overall and slightly ahead of Claude Fable 5. Additionally, a BenchmarkList screenshot shared by @davidthesong shows Claude Opus 5 marked as the new global SOTA No. 1, covering 52 benchmarks with an experimental ECI score of 154.80. Screenshots of the GDPval-AA v2 leaderboard, which measures real-world work performance, also confirm Opus 5 leading Fable 5.

Unconfirmed

@Hesamation noted that despite Claude Opus 5 topping the overall intelligence index, Fable 5 still maintains a lead in specific Coding Agent capabilities.

Why it matters

Claude Opus 5 reaching the top of the comprehensive intelligence index marks another elevation in the capability ceiling of large AI models. Meanwhile, the differentiated performance between Opus 5 and Fable 5 in general tasks versus coding agent tasks provides clear guidance for developers selecting models for different application scenarios.
