openai/swarm
OfficialEducational framework exploring ergonomic, lightweight multi-agent orchestration. Managed by OpenAI Solution team.
Swarm is an experimental, educational open-source framework developed by OpenAI for lightweight multi-agent orchestration in Python. It uses two core primitives -- Agents with instructions and tools, and handoffs -- to enable controllable, testable coordination without complex setups.

Our Review
Swarm (openai/swarm) commands 21,274 GitHub stars -- OpenAI's Python framework for ergonomic multi-agent orchestration under MIT license. It prioritizes lightweight coordination through agents and handoffs for real-world scalability.
What Swarm does:
- •Agent creation Define agents with name, instructions, and functions in a single class for immediate use.
- •Handoff mechanism Agents call functions to transfer conversations to other agents, enabling dynamic routing.
- •Tool integration Attach Python functions as tools so agents execute custom logic during runs.
- •Client execution Run agents with message lists via Swarm client for structured conversations.
- •Streaming support Receive real-time message updates as agents process and handoff.
- •Testable design Primitives allow unit testing of agent behaviors and handoff logic.
Swarm ecosystem:
- •OpenAI Agents SDK Production-ready successor with improvements and active OpenAI maintenance.
- •OpenAI integrations Works with OpenAI APIs for agent instructions and responses.
- •Community examples Repo provides usage patterns for haikus, transfers, and multi-agent chains.
- •Evaluation utils Built-in tools assess agent performance on benchmarks.
Getting started:
Install with pip install git+https://github.com/openai/swarm.git. Requires Python 3.10+. Run the example: create Swarm client, define Agent A with transfer function to Agent B, execute with user message to switch agents. Response prints haiku from Agent B. Full docs in repo.
Cons
- Experimental and educational -- OpenAI recommends Agents SDK for production.
- No official releases -- Install directly from GitHub repo.
- Git-based pip install -- Use SSH or HTTPS, not standard PyPI package.
- Python 3.10+ only -- Limits older environments.
Our Verdict
Vibe Builders prototype agent apps fast. Handoffs let you chain behaviors without glue code. Skip if you skip experimental tools.
Developers build scalable networks. Test primitives catch issues early. Skip if production stability matters first.
Teams learn multi-agent patterns. Repo examples guide quick starts. Skip if you need enterprise support now.
Frequently Asked Questions
What is OpenAI Swarm?
Swarm is an educational framework for lightweight multi-agent orchestration. It uses agents and handoffs to coordinate AI behaviors. OpenAI released it with 21,274 stars as of 2026.
Who created Swarm?
OpenAI Solution team created and manages Swarm. They evolved it into the OpenAI Agents SDK. The repo stays open for educational use.
How do you install Swarm?
Install Swarm with `pip install git+https://github.com/openai/swarm.git`. It requires Python 3.10 or higher. SSH variant uses `git+ssh://git@github.com/openai/swarm.git`.
Swarm vs OpenAI Agents SDK?
Swarm focuses on educational handoffs without production features. Agents SDK adds improvements for real apps. Choose Swarm when learning basics, choose Agents SDK when building production systems.
Is Swarm production-ready in 2026?
Swarm remains experimental in 2026. OpenAI directs production to Agents SDK. It suits prototypes with its 2,272 forks showing community tests.
