What is OpenAI Agents SDK?

The Agents SDK is a Python framework designed for creating sophisticated multi-agent AI systems. It allows developers to configure Large Language Models (LLMs) with specific instructions, tools, and guardrails, enabling them to delegate tasks between different agents (handoffs) for complex workflows. The SDK is provider-agnostic, supporting OpenAI's APIs as well as over 100 other LLMs, offering flexibility in model choice. This SDK is ideal for developers and AI engineers looking to build intelligent applications that require coordinated actions from multiple AI agents. It provides built-in features for managing conversation history, tracing agent runs for debugging and optimization, and incorporating human oversight. With support for real-time voice agents and optional integrations for Redis sessions, it facilitates the creation of dynamic and interactive AI solutions.
