Skip past model table

A model’s rank is 1 + the number of models that clearly beat it. Ranks count the models listed here. LMArena ranks gemini-4-argon-high (1533.5) above all of them: not ranked here, because not in the price feed this site reads. How they work

When a cache-read rate is unlisted, blended estimates use the selected tier’s full input rate.

AI models ranked by General capability, then by price for a Balanced workload.
