About

AG2 is a Python framework for building agents that interact with each other and use tools, supporting autonomous and human-in-the-loop workflows. Its README describes multi-agent conversation patterns, and the package is installed from PyPI as ag2. From v1.0 the classic autogen namespace moved to a separate AG2 Classic repository, so the ag2 import no longer provides those classes. The docs list agents, models, tools and structured output as key concepts.
