Capability: Arena leaderboard dataset (CC-BY-4.0), Arena text / creative_writing, published 2026-09-02. Pricing: OpenRouter, retrieved 2026-09-10. (input x 3 + output x 1) / 4.

What this measures: Human pairwise preference votes. Measures perceived answer quality on this category, not correctness on a fixed test set. For each model this is the probability it beats the board leader in a head-to-head human vote — 0.50 means a dead tie and is the best possible value.
