Usage counts public Tokscale submissions only; hidden accounts are excluded. Scores are the best result each source reports for the model, with its effort and agent or harness; open a score for its source and date. Prices are list prices from models.dev, and every $/1M figure is an estimate at list prices, not what anyone paid. Usage and scores are shown side by side; one does not explain the other. Sorting by a score puts models that were not evaluated last.
