Claude Opus 5 tops Artificial Analysis Intelligence Leaderboard

Opus 5 is currently #1 on Artificial Analysis Intelligence Leaderboard

Artificial Analysis updated its model leaderboard. Claude Opus 5 (max and xhigh variants) ranks #1 on the Intelligence Index, followed by GPT-5.6 Sol (max). Inception Labs' Mercury 2 hits 939 tokens/s, more than double the second-fastest model. Gemini 2.5 Flash-Lite has the lowest latency at 0.35s. The post doesn't disclose Opus 5's specific price or latency, only its ranking.

Why it matters: Opus 5 topping the composite intelligence chart over GPT-5.6 Sol is a direct signal for the Claude-heavy audience. But this is a leaderboard refresh, not a new model release — limited information gain, so 72 at the featured threshold.
