Kimi K3.1 Pro vs 
GPT 6.1 Sol
Both are currently SOTA. Each row is one board’s result, and the marked figure is the one that board ranks higher. Rows are not added together, so there is no overall winner: the boards measure different things, and where they differ, the difference is the finding.Each rank is the board’s own: the rank it publishes, or the model’s place in the board’s own order where it publishes none. Scores from different boards cannot be compared.
