AG2Open-source framework for building and orchestrating multi-agent LLM workflows.

4.7 (6)

Reviewed by Daniel Nikulshyn·Updated July 2026

Overview

AG2 is a developer framework designed to coordinate multiple LLM-powered agents that can collaborate, delegate tasks, and execute tools to solve complex problems. It provides abstractions for defining agent roles, conversation patterns, and shared memory, making it easier to build systems where several specialized agents work together rather than relying on a single monolithic prompt. The framework supports human-in-the-loop interactions, code execution, and integration with a range of model providers and external tools. It targets use cases such as research assistants, automated coding pipelines, data analysis workflows, and customer-facing agents that need structured reasoning and task decomposition. As an evolution of earlier multi-agent projects in the open-source ecosystem, AG2 emphasizes extensibility and community contribution, giving teams a foundation to prototype, optimize, and deploy agentic applications.

I've evaluated a lot of these over the years. What stands out here is configurable agent roles and conversations — handled better than most — and strong support for multi-agent collaboration. Requires developer expertise to set up is my one real gripe. Worth the time if this is your use case.

Use it every day

Honestly didn't expect to like it this much. Human-in-the-loop workflows is exactly what I needed, and open-source and extensible. I do wish requires developer expertise to set up, but I reach for it almost every day now and it just clicks.

Q&A

What is AG2?

AG2 is an open-source Python framework for building, orchestrating, and scaling multi-agent AI systems. Built by the creators of AutoGen, AG2 enables developers and enterprises to compose systems of AI agents that collaborate to solve complex tasks.

Asked by Abebe Girma · Oct 23, 2025

What is a multi-agent AI framework?

A multi-agent AI framework provides the tools and abstractions to build systems where multiple AI agents work together. Instead of a single AI model handling everything, agents specialize in different tasks and coordinate with each other—leading to more reliable, scalable, and auditable AI workflows.

Asked by Tobias Hartmann · Sep 21, 2025

How is AG2 different from AutoGen?

AG2 is the production-ready evolution of AutoGen. While AutoGen is a research framework for multi-agent conversations, AG2 adds enterprise features like visual orchestration, persistent context, state management, and observability for deploying multi-agent systems at scale.

Asked by Carlos Mendoza · Sep 20, 2025

Is AG2 open source?

Yes. AG2 is open source at its core, available on GitHub under a permissive license. Enterprise features and managed hosting are available for teams that need production-grade support, security, and scalability.

Asked by Winifred Adeyemi · Aug 28, 2025

What programming languages does AG2 support?

AG2 is a Python-native framework. It integrates with popular Python AI/ML libraries and supports any LLM provider including OpenAI, Anthropic, Google, and open-source models. AG2 also supports agent communication protocols like A2A and MCP for interoperability.
