# OpenAI API models and prices

The GPT-6 family is sold through the Responses API, which is also where tool calling, hosted shell, computer use and remote MCP live. Prompts over 272K tokens are billed at a higher rate for the whole request, and a paid Fast mode replaced what used to be called Priority processing.
