gpt

Call the GPT API (gpt-5.2, gpt-5.4, gpt-5.4-mini, gpt-5.5, gpt-5.3-codex) through RunAPI using the official OpenAI SDK or any OpenAI-compatible client. Use when the user asks for OpenAI / GPT chat, streaming completions, vision input, tool use / function calling, reasoning effort, the Responses API, or Codex coding tasks, or when they want to point an existing OpenAI SDK setup at RunAPI as the base URL.
