About Ag2
AG2 is an open source Python framework for building, orchestrating and scaling multi agent AI systems, created by the original creators of AutoGen. It lets developers define teams of specialized agents that converse, use tools and hand work to each other, and it sits at the core of a wider commercial platform the company calls AgentOS.
The framework suits developers and research teams building agent systems in code, while AgentOS targets organizations that want to run agents as a managed workforce. AgentOS has three parts. The Orchestrator connects agents built on AG2, Google ADK, OpenAI and LangChain into one team, keeps unified state across a task lifecycle and communicates over A2A and MCP. Studio builds agent workforces through code, low code or a visual editor, adds cryptographic identities, role based access and permission boundaries, tests against golden datasets in parallel simulations, and lets agents learn from human corrections. Applications package multi agent systems so anyone in a company can launch them, deployed to the web, Slack or Teams or embedded through a headless SDK. AG2 Space is a separate macOS app with shared rooms where each person has an agent that runs on their Mac using an existing Claude Code or Codex plan, and agents hand off work and ask people for approval.
The AG2 framework is free under the Apache 2.0 license. AgentOS and AG2 Space are offered through request access and early access, and no pricing is published.
AG2 continues the AutoGen line of work under new stewardship and is distinct from Microsoft's own AutoGen project.
