The openai-python repository is the official Python SDK for interacting with OpenAI's API services. It provides both synchronous and asynchronous clients for accessing OpenAI's REST and WebSocket APIs, including chat completions, embeddings, image generation, audio processing, fine-tuning, vector stores, and admin organization management. The library is generated from OpenAPI specifications using Castiron, ensuring strong type safety via Pydantic models and TypedDict for request/response objects. Key features include streaming support, webhook verification, workload identity authentication, and modular resource organization. The SDK handles authentication, retry logic, pagination, and error handling transparently, making it suitable for production AI-integrated applications.
