// cómo funciona

Cómo funciona

  1. Pick an agent to improve

    Choose an existing agent workload - the repo includes a full coding-agent training example.

  2. Clone the repository

    Training setups are run from a source checkout.

  3. Sync the environment

    Use uv sync and the provided setup script to prepare the training stack for your CUDA version.

  4. Run your first training job

    Start from an included example, collect trajectories, and launch a training run.

// características

Por qué gusta tanto

Framework-agnostic training

Designed to train agents built with popular frameworks without rewriting them around the trainer.

Reinforcement learning for agents

Applies RL (with veRL integration scripts) to multi-step agent trajectories.

Complete coding-agent example

Ships an end-to-end example that trains a coding agent on SWE-bench-style tasks with data cleaning and reward-hacking prevention.

Lightweight architecture

Keeps the training architecture to three lightweight components per the README.

Documented results

The README reports measured gains for its examples (for example SWE-bench Verified improvements in the coding-agent pipeline).

Examples and community projects

Includes additional examples and a catalog of community projects built on it.

  1. Clone the repository

    Get the source code from GitHub and enter the project directory.

    git clone https://github.com/microsoft/agent-lightning.git
    cd agent-lightning
  2. Sync the environment

    The README's example installation targets a CUDA machine and uses uv plus the veRL setup script.

    uv sync
    bash scripts/setup_verl.sh 0.8.0 cu130 # example versions - see README installation
  3. Start from an example

    Open the examples in the repo (including the coding-agent training example) and adapt one to your agent.

    # Browse the Examples section linked from the README and run one pipeline

Preguntas frecuentes

Who maintains this project?

It is maintained by Microsoft (Microsoft Research) as an open-source project on GitHub.

Is it free to use?

Yes - Agent Lightning is MIT licensed and free to use.

Does it need a paid API key?

Training needs models to train and roll out: you bring your own model endpoints or local weights and the GPU capacity; the framework itself sells no API.

How does it compare to alternatives?

Compared with fine-tuning libraries like TRL, Agent Lightning is specialized for agents - trajectory-based training designed to wrap existing agent frameworks rather than single-turn LLM training.

How do I get started?

Clone the repo, run uv sync, follow the installation guide for your CUDA setup, and run one of the included examples.
