Responses (OpenAI-compatible)
The OpenAI Responses API, so Codex and responses.create work with a Runcrate key and Runcrate model ids. Same billing, limits and models as chat completions. Nothing is stored: previous_response_id, conversation and background answer 400, and hosted tools (web_search, file_search, …) are left out.
