It supports any agent framework (LangChain, AutoGen, CrewAI, etc.) and allows selective optimization of agents in multi-agent systems. The framework uses a modular architecture with LightningStore as a central hub for tasks, traces, and resources, supporting algorithms like RL, automatic prompt optimization, and supervised fine-tuning. ## Full article daily.dev links to this article rather than hosting it.
