# Magentic-One

> Magentic-One is now available as part of the `autogen-agentchat` library.
> Please see the [user guide](https://microsoft.github.io/autogen/stable/user-guide/agentchat-user-guide/magentic-one.html) for information.

> Looking for the original implementation of Magentic-One? It is available [here](https://github.com/microsoft/autogen/tree/v0.4.4/python/packages/autogen-magentic-one).

[Magentic-One](https://aka.ms/magentic-one-blog) is a generalist multi-agent system for solving open-ended web and file-based tasks across a variety of domains. It represents a significant step forward for multi-agent systems, achieving competitive performance on a number of agentic benchmarks (see the [technical report](https://arxiv.org/abs/2411.04468) for full details).

When originally released in [November 2024](https://aka.ms/magentic-one-blog) Magentic-One was [implemented directly on the `autogen-core` library](https://github.com/microsoft/autogen/tree/v0.4.4/python/packages/autogen-magentic-one). We have now ported Magentic-One to use `autogen-agentchat`, providing a more modular and easier to use interface. To this end, the older implementation is deprecated, but can be accessed at [https://github.com/microsoft/autogen/tree/v0.4.4/python/packages/autogen-magentic-one](https://github.com/microsoft/autogen/tree/v0.4.4/python/packages/autogen-magentic-one).

Moving forward, the Magentic-One orchestrator [MagenticOneGroupChat](https://microsoft.github.io/autogen/stable/reference/python/autogen_agentchat.teams.html#autogen_agentchat.teams.MagenticOneGroupChat) is now simply an AgentChat team, supporting all standard AgentChat agents and features. Likewise, Magentic-One's [MultimodalWebSurfer](https://microsoft.github.io/autogen/stable/reference/python/autogen_ext.agents.web_surfer.html#autogen_ext.agents.web_surfer.MultimodalWebSurfer), [FileSurfer](https://microsoft.github.io/autogen/stable/reference/python/autogen_ext.agents.file_surfer.html#autogen_ext.agents.file_surfer.FileSurfer), and [MagenticOneCoderAgent](https://microsoft.github.io/autogen/stable/reference/python/autogen_ext.teams.magentic_one.html) agents are now broadly available as AgentChat agents, to be used in any AgentChat workflows.

Lastly, there is a helper class, [MagenticOne](https://microsoft.github.io/autogen/stable/reference/python/autogen_ext.teams.magentic_one.html#autogen_ext.teams.magentic_one.MagenticOne), which bundles all of this together as it was in the paper with minimal configuration
