Agent Lightning v1.0

What a bizarre README. From the top:

> 3,500-Line Lightweight Agentic RL Framework for Training Agents with Real Harnesses!

Ok, it's a framework. That can mean many things. Let's look at the "Key Features."

> ~3,500 lines of code: We treat simplicity as the first principle.

???

How does a _multi-trillion dollar company_ think this is good presentation?

seems to be a toolkit for taking some LLM model and training/finetuning it further based on some agentic task (like painting, playing a video game, etc)

So this is the Xzibit meme of agent skills?

how good is this?

Agent Lightning v1.0.1 marks the first official release of the Agent Lightning Skill, which helps coding agents optimize other AI agents.

Provide an editable agent and a benchmark, and the skill guides systematic improvements to prompts, tools, workflows, models, and reasoning settings—balancing accuracy, cost, latency, and reliability through measured iteration.
