# lerobot vs ml-agents

lerobot and ml-agents share 3 technologies: torch, gymnasium, and pillow. Both are written in Python.

- [huggingface/lerobot](https://seerepo.com/r/huggingface/lerobot): 🤗 LeRobot: Making AI for Robotics more accessible with end-to-end learning
- [Unity-Technologies/ml-agents](https://seerepo.com/r/Unity-Technologies/ml-agents): The Unity Machine Learning Agents Toolkit (ML-Agents) is an open-source project that enables games and simulations to serve as environments for training intelligent agents using deep reinforcement learning and imitation learning.

## What they share and what sets them apart

- In common: torch, gymnasium, pillow
- Only in lerobot: Hugging Face, safetensors, einops, torchvision
- Only in ml-agents: h5py

## Side by side

| | lerobot | ml-agents |
|---|---|---|
| Size | 337,914 lines written, 635 code files | 81,989 lines written, 300 code files |
| Who writes it | 2.5% of its commits signed by AI. With GitHub Copilot, Claude Code, and Cursor | 0.1% of its commits signed by AI. With Claude Code |
| Activity | Last push November 8, 2026, 1,854 commits, 28,744 stars | Last push October 30, 2026, 3,177 commits, 19,822 stars |
| Tests | 365 test files. 58.7% of its code files have a test that imports them | 160 test files. 55.3% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
