Standardize OpenAI API direct-model integration for chat, vision, image generation, structured outputs, reasoning effort, streaming, and tool calling. Use when Codex needs to choose an OpenAI model, wire Responses API or Chat Completions compatible request/response flows, expose reasoning effort, JSON object, JSON schema, tool/function calling, stream controls, model selectors, or shared progress and error states. Do not use for ChatGPT consumer-app settings, Apps SDK orchestration, Agents SDK orchestration, non-OpenAI providers, or prompt-only work with no integration change.
