🤖 AG2: Open-Source AgentOS (formerly AutoGen)

This is the evolution of the well-known AutoGen framework, now rebranded and positioned as an open-source AgentOS. Written in Python, it continues to focus on multi-agent conversation and complex collaborative workflows. The hard part is not getting a single model to answer prompts, but orchestrating multiple agents with different roles to cooperate, correct each other, and execute long-horizon tasks. The new version inherits its core multi-agent orchestration capabilities while introducing support for the Model Context Protocol (MCP), further expanding the agents' ability to interact with external tools and local resources.
