agent-lightning: The absolute trainer to light up AI agents

Agent Lightning is a training framework developed by Microsoft Research that optimizes AI agents with minimal code changes. The tool works with any agent framework like LangChain, OpenAI, or AutoGen, using reinforcement learning and automatic prompt optimization to improve agent performance. It collects agent interactions through lightweight helpers, stores them in a central hub, and applies algorithms to refine prompts and update models while agents continue running normally.
