Claude Opus 5 tops Artificial Analysis intelligence rankings, while rivals lead on speed, latency, cost, and context size

Artificial Analysis ranks Claude Opus 5 variants as the highest-scoring models on its Intelligence Index, ahead of Claude Fable 5 and GPT-5.6 Sol. The leaderboard also highlights separate leaders for output speed, latency, price, and context window, showing that no single model dominates every metric.

The results underscore a growing split between intelligence benchmarks and operational factors like cost and speed. As AI buyers compare models, leaderboards that combine quality, price, latency, and context may increasingly shape procurement and developer adoption decisions.
