USD token-only estimates using each offering’s published default tier. 1M tokens are an aggregate workload, not a single request. Cache savings, batch discounts, long-context surcharges, tools, taxes and negotiated rates are excluded. Tokenizers and capabilities may differ; lower price does not establish equivalent quality.
Current cost comparison is paused because one or both quotes are not verified. The rates below are historical references, not current offers.
