OpenAI Agents SDK
The OpenAI Agents SDK is a lightweight framework for building multi-agent workflows in Python and TypeScript. Primitives include agents (LLMs with instructions, tools, guardrails), handoffs between specialists, guardrails for safety checks, sessions for conversation history, tracing for run observability, and realtime agents for voice workflows. The SDK is provider-agnostic and supports OpenAI Responses and Chat Completions plus other LLM providers.
