OpenAI Agents SDK

OpenAI Agents SDK

The OpenAI Agents SDK is a lightweight yet powerful framework for building multi-agent workflows. It is provider-agnostic, supporting the OpenAI Responses and Chat Completions APIs, as well as 100+ other LLMs.

[!NOTE] Looking for the JavaScript/TypeScript version? Check out Agents SDK JS/TS.

Core concepts:

1. Agents: LLMs configured with instructions, tools, guardrails, and handoffs
2. Agents as tools / Handoffs: Delegating to other agents for specific tasks
3. Tools: Various Tools let agents take actions (functions, MCP, hosted tools)
4. Guardrails: Configurable safety checks for input and output validation
5. Human in the loop: Built-in mechanisms for involving humans across agent runs
6. Sessions: Automatic conversation history management across agent runs
7. Tracing: Built-in tracking of agent runs, allowing you to view, debug and optimize your workflows
8. Realtime Agents: Build powerful voice agents with gpt-realtime-1.5 and full agent features

Get started

To get started, set up your Python environment (Python 3.10 or newer required), and then install OpenAI Agents SDK package.

venv

python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install openai-agents

For voice support, install with the optional voice group: pip install 'openai-agents[voice]'. For Redis session support, install with the optional redis group: pip install 'openai-agents[redis]'.

uv

If you're familiar with uv, installing the package would be even easier:

uv init
uv add openai-agents

For voice support, install with the optional voice group: uv add 'openai-agents[voice]'. For Redis session support, install with the optional redis group: uv add 'openai-agents[redis]'.

Run your first agent

from agents import Agent, Runner

agent = Agent(name="Assistant", instructions="You are a helpful assistant")

result = Runner.run_sync(agent, "Write a haiku about recursion in programming.")
print(result.final_output)

# Code within the code,
# Functions calling themselves,
# Infinite loop's dance.

(If running this, ensure you set the OPENAI_API_KEY environment variable)

Acknowledgements

We'd like to acknowledge the excellent work of the open-source community, especially:

• Pydantic
• Requests
• MCP Python SDK
• Griffe

This library has these optional dependencies:

• websockets
• SQLAlchemy
• any-llm and LiteLLM

We also rely on the following tools to manage the project:

• uv and ruff
• mypy and Pyright
• pytest and Coverage.py
• MkDocs

We're committed to continuing to build the Agents SDK as an open source framework so others in the community can expand on our approach.
