# LeRobot, brain

Hugging Face's open-source robot-learning framework. LeRobot is a framework, not a brain that powers robots directly: it HOSTS other models (pi0, pi0.5, GR00T N1.5) and provides datasets, simulation environments, training tooling, and a multi-GPU + plugin runtime. v0.4.0 added Datasets v3.0, LIBERO and Meta-World simulators, and the Robot Learning Course.

- **Slug:** lerobot
- **Type:** Framework
- **Maturity (DEPLOY ladder):** Production
- **Open source:** yes

## Architecture

Open-source robot-learning framework. Library-style hosting of VLA models (pi0, pi0.5, GR00T N1.5) plus datasets, simulation environments (LIBERO, Meta-World), training tooling, multi-GPU support, plugin system. Released v0.4.0 with the upgrades above.


## Key facts

- **Verified-vs-claimed clarification:** LeRobot is a FRAMEWORK that hosts VLA models. It does not power robots directly. Use the Hosts relation, not Powers.
- **Position in the ecosystem:** De facto open hub for robotics foundation models on the Hugging Face platform
- **Educational layer:** Includes Robot Learning Course; explicit developer-onboarding mission
- **Source-list correction:** The source list's '6 robots' figure conflated framework with hosted models; the framework itself is the entity here

## Hosts (2)

This brain is a framework that hosts other brains. Hosting means the host brain provides the runtime and tooling for the hosted brain to operate on supported robot platforms.
