Every model for which we have at least a price or a specification from an open source. An unfiltered list: it includes deprecated models and models without a single independent score.
The price is the developer's own, if they sell this model; if not, the cheapest offer among providers is taken, with the input-and-output pair coming entirely from one price list rather than as two minimums from different ones. Base per-token tier only. A dash means the price is absent from open sources, not that the model is free.
