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

Acknowledgements
We'd like to acknowledge the excellent work of the open-source community, especially:
This library has these optional dependencies:
We also rely on the following tools to manage the project:
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.
