›What is AG2?
AG2 is an open-source Python framework for building multi-agent AI systems through structured conversations between specialized agents. Its AgentOS runtime coordinates agents from AG2 and other frameworks using shared state, A2A, and MCP protocols. Developers can also run code locally or in Docker sandboxes and add human approval steps.
›What are the pros and cons of AG2?
Strengths
Open-source framework licensed under Apache 2.0
Existing AutoGen 0.2.x workflows can generally migrate by changing the import from autogen to ag2
Cross-framework orchestration supports agents from CrewAI, LangChain, and LlamaIndex
Human-in-the-loop workflows are supported through UserProxyAgent
Local and Docker-based code execution are available without separate infrastructure
Trade-offs
The framework supports Python only, specifically Python 3.10 through 3.13
Enterprise AgentOS, Studio, and Applications use custom pricing
AgentOS access is presented through a request-access and early-access process
›What are AG2’s key features?
Orchestrates teams of specialized agents across AG2, Google ADK, OpenAI, and LangChain
Maintains shared state across task lifecycles
Supports A2A and MCP protocols
Provides human-in-the-loop workflows with configurable approval points
Runs agent-generated code locally or in Docker sandboxes
Supports OpenAI, Anthropic, Google, Mistral, Azure, and local models
›What are the best use cases for AG2?
Coordinate research, analysis, and decision-making agents as one team
Build coding agents that write, execute, and debug code
Add human approval to otherwise autonomous business workflows
Connect agents built with different frameworks through AgentOS
Maintain shared context across multi-step tasks

›Who is AG2 best for?
developersUseful for Python developers building multi-agent applications with code execution, structured conversations, and human approval steps.
enterpriseEnterprise teams can use AgentOS to coordinate agents across frameworks, but access and pricing require contact with AG2.
small teamSmall teams can start with the free open-source framework when they have the Python skills to assemble and operate their own agents.
Not for
- Teams that need a non-Python implementation, since AG2 supports Python 3.10 through 3.13.
- Buyers looking for a fixed, publicly listed price for enterprise AgentOS, Studio, or Applications.

CrewAIChoose this instead if you want another platform centered on building multi-agent workflows.→
AutoGenChoose this instead if you need Microsoft's original AutoGen project or its Python and .NET support.→
