Pros and Cons of Magentic-One, AutoGen, LangGraph, CrewAI, and OpenAI Swarm

The topic of multi-AI agents in generative artificial intelligence is gaining momentum, with major tech giants releasing various frameworks around it.

But which multi-AI agent framework should one choose?

With OpenAI releasing Swarm and Microsoft’s Magentic-One, this field has become quite confusing. Therefore, to clear up any doubts, I will attempt to explain the main features, advantages, and disadvantages of each framework to help you decide which is best for you. We will discuss

AutoGen (Microsoft)

LangGraph (LangChain)

CrewAI

OpenAI Swarm (OpenAI)

Magentic-One (Microsoft)

1. AutoGen

AutoGen is Microsoft’s most popular and earliest framework in this field, better suited for software development tasks.

Features:

  • It mainly involves two agents, the user and the assistant.

  • User-Agent and Assistant-Agent interaction: In the AutoGen user assistant agent model, the User-Agent can provide prompts or requests, while the Assistant-Agent generates and executes code.

  • Assistant-Agent not only handles code generation but also execution, returning results to the user or other agents in the setup.

  • Multi-agent orchestration specifically for code tasks, but can also handle other tasks.

  • Can provide human guidance during the interaction.

  • Strong community support from Microsoft.

Limitations:

  • Not intuitive enough, not suitable for non-programmers.

  • Complex setup, especially for local LLM; requires a proxy server.

  • May be mediocre if not for software development tasks.

2. CrewAI

Due to CrewAI’s intuitive nature and ease of setup, it is often the go-to choice for people building quick demos for any multi-AI agent task.

Features:

  • Very intuitive, primarily relies on prompt writing.

  • Creating new agents and joining the ecosystem is very easy. You can create hundreds of agents in minutes.

  • Non-technical users can also operate it easily.

  • Due to LangChain integration, it works well with most LLM providers and local LLMs.

Limitations:

  • Limited flexibility and customization.

  • Suitable for basic use cases and not for complex programming tasks.

  • Some bugs exist in the interaction between agents.

  • Limited community support.

3. LangGraph

My personal favorite is LangGraph, which can be used for any multi-AI agent task and provides great flexibility.

Features:

  • Built on top of LangChain; based on the idea of directed cyclic graphs.

  • It is not just a multi-AI agent framework, it has more functionalities.

  • Highly flexible and customizable, supporting almost any multi-agent orchestration application.

  • It is an extension of LangChain, thus receiving strong community support.

  • Works well with open-source LLMs and any API.

Limitations:

  • Lacks comprehensive documentation.

  • Not friendly enough for non-programmers or beginners.

  • Requires good programming skills, especially understanding graphs and logical flows.

4. OpenAI Swarm

OpenAI recently released Swarm, and I must say, if you want to get started, it is the simplest multi-AI agent framework.

Features

  • Suitable for multi-AI agent beginners.

  • Main focus on simplifying “agent creation” and context switching between agents (called handoffs).

  • Creating a brief demo is very simple.

Limitations

  • Does not support LLMs other than OpenAI API.

  • Not suitable for production deployment.

  • Not flexible enough.

  • Poor community support; you can’t even ask questions on GitHub!

5. Magentic-One

The newest member on this list is Microsoft’s Magentic-One (their second framework), which is also designed to simplify their existing AutoGen framework.

Features

  • Similar to Swarm, suitable for non-programmers and easy to run.

  • Includes 5 agents in the default package, one management agent and 4 others: WebSurfer for browsing and interacting with web pages, FileSurfer for managing and navigating local files, Coder focused on writing and analyzing code, and ComputerTerminal providing console access for running programs and installing libraries.

  • Built on AutoGen, more like a general-purpose framework.

  • Includes AutoGenBench, a tool specifically designed for analyzing agent performance.

Limitations

  • Support for open-source LLMs is complicated.

  • Not flexible enough; feels more like an application than a framework to me.

  • No documentation and community support available yet.

So, what is the best multi-AI agent framework?

In my view (having used all these packages),

  • For software development: AutoGen (Microsoft) — best suited for tasks involving code generation and complex multi-agent coding workflows.

  • Best for beginners: OpenAI Swarm and CrewAI — user-friendly, great for those unfamiliar with multi-agent AI and do not require complex setups.

  • Best for complex tasks: LangGraph — offers high flexibility, built for advanced users, allowing custom logic and orchestration.

  • Open-source LLM: LangGraph — unlike some other frameworks, it integrates well with open-source LLMs and supports various APIs. Even CrewAI works well.

  • Best community support: AutoGen has good community support to help you with tricky issues.

  • Always available: CrewAI — quick and intuitive setup, suitable for demos or tasks requiring rapid agent creation. Even Swarm and Magentic-One are decent, but lack sufficient community support.

  • Cost-effective: Magentic-One — comes with pre-packaged setups and general methods that save initial costs. Swarm and CrewAI can also be considered.
