microsoft/agent-lightning
The absolute trainer to light up AI agents.
This tool helps AI developers and researchers significantly improve the performance of their AI agents by training them with various optimization algorithms. It takes your existing agent, regardless of the framework used, and outputs a more capable, optimized version of that agent. This is for anyone building, deploying, or managing AI agents who wants to enhance their effectiveness without major code changes.
15,409 stars.
Use this if you have an AI agent or multi-agent system and want to boost its capabilities using advanced training methods like reinforcement learning or prompt optimization.
Not ideal if you are looking for a pre-built agent solution rather than a tool for training and optimizing your own custom agents.
