Summary

In summary, Agency Swarm is the only framework that has:

No Predefined Prompts

It doesn’t write prompts for you, giving you full control over agent behavior.

Automatic Error Correction

Prevents hallucinations with automatic type checking and error correction.

Uniform Communication Flows

Allows you to define communication flows in any way you want.

Detailed Comparison

Here’s how Agency Swarm compares to 2 other most popular multi-agent frameworks.
CriteriaAgency SwarmAutoGenCrewAI
Origins 🏁✅ Originated from a real AI agency building AI agents for clients worldwide.✅ Originated as a research experiment.❌ Originated as a funding vehicle, rather than a real production framework.
Design & Architecture 🏗️✅ Super lightweight framework with minimal abstractions. Built on top of the OpenAI Assistants API.✅ Event-driven architecture with support for both ChatCompletions and Assistants API.❌ Lacks a clear architectural design. Built on top of LangChain with numerous unnecessary abstractions.
Reliability 🔍✅ Robust type checking and validation for all tools with Pydantic.❌ Type hints but no validation.❌ Some validation is possible when using BaseTool, although the interface is not convenient to use.
Flexibility 🔄✅ No predefined prompts. Uniform communication.❌ Contains predefined prompts. Limited, but customizable communication flows.❌ Numerous predefined prompts. Only two ways of communication.
Scalability 📈✅ Easily scalable. Adding another agent only requires placing it in the agency chart.❌ Although it’s simple to add an agent into teams, it’s almost impossible to define custom communication between them.❌ Although it’s easy to add agents into crews, it’s not possible to create custom communication between them.
Deployability 🚀✅ Easily deployable with special callback functions. Offers open-source templates and tutorials.✅ Deployment with AutoGen studio.❌ Deployment via enterprise platform. No open-source deployment guides.
Open Source Model Support 🌐⚠️ Limited support with Astra Assistants API.✅ Moderate open-source model support.✅ Full open-source model support.

Summary

  • Agency Swarm - best for real business-oriented use cases.
  • AutoGen - best for research, experimentation and novel AI applications.
  • CrewAI - best for local development and playgrounds with open-source models.
