agent-lightning

What problem does it solve?

Train and optimize AI agents using the Agent Lightning framework to streamline training, tracing, resource management, and reward design across multi-agent pipelines.

Core Features & Use Cases

• Architecture Flow and central tracing with LightningStore for scalable agent training.
• Instrumentation of agent code with emit_xxx calls for observability and reward signals.
• Support for Reinforcement Learning (GRPO/PPO) and Automatic Prompt Optimization (APO) workflows, plus framework adapters.
• End-to-end trainer configuration and customization with configurable runners, algorithms, and stores.

Quick Start

Install the package, configure a minimal trainer with a simple store, and run a basic training loop.
