About the 0 to 100 score: Relative score: 100 is the top model we price on Code Arena, 0 is the 50th ranked model on the full leaderboard. Raw scores differ by leaderboard, so we rescale them.

How we pick
Quality is the LMArena score for each task, built from blind side by side human votes. Where a model is listed at several effort levels we use its best one. Value divides the score above the 50th ranked model on that leaderboard by the blended price, (3 x input + output) / 4 per 1M tokens, and only counts models at or above the median score of the models we price. Local picks use the same Text Arena score and the Q4 download size. Close scores are often inside the margin of error, so treat ranks 1 to 3 as a shortlist, not a final verdict.
