- [Physical-Intelligence/openpi](https://seerepo.com/r/Physical-Intelligence/openpi)

## What they share and what sets them apart

- In common: Rich, orbax-checkpoint, torch, jax, flax, pillow
- Only in keras: h5py, jax2onnx, onnxscript, tf2onnx, TensorFlow, ml-dtypes, scikit-learn, grain, litert-torch, openvino, torch-xla
- Only in openpi: opencv-python, einops, transformers, sentencepiece, imageio, beartype

## Side by side

| | keras | openpi |
|---|---|---|
| Size | 327,091 lines written, 625 code files | 17,200 lines written, 52 code files |
| Who writes it | 0.6% of its commits signed by AI. With Gemini CLI, Jules, Claude Code, and Cursor | 0.7% of its commits signed by AI. With Claude Code |
| Activity | Last push November 12, 2026, 11,798 commits, 64,422 stars | Last push August 24, 2026, 150 commits, 14,578 stars |
| Tests | 320 test files. 34.9% of its code files have a test that imports them | 14 test files. 26.9% 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.
