How we count
Prices are per million tokens. The big number on each row is blended 3 in : 1 out, the way most work uses a model. A price below Google Vertex AI's own is listed as cheapest only when the provider says why. Anthropic trained Claude Sonnet 4 and sells it on no catalog we read, so the price every row is measured against is Google Vertex AI's.
