LLM API pricing: OpenAI, Claude and Gemini per 1M tokens

Standard pay-as-you-go prices in USD per 1 million tokens, excluding tax, for 12 models we track. Where a model has prompt-length tiers, each tier is listed with its condition. Batch, priority and regional-endpoint variants are not shown here. Products billed per request are listed after the token tables.

This is not a full market list: we only include models whose prices we have checked on the vendor's own pricing page. Introductory prices are flagged with their end date.
