# DiffSynth-Studio vs ray

DiffSynth-Studio and ray share 8 technologies: torch, transformers, einops, torchvision, safetensors, accelerate, peft, and imageio. Both are written in Python.

- [modelscope/DiffSynth-Studio](https://seerepo.com/r/modelscope/DiffSynth-Studio): Enjoy the magic of Diffusion models!
- [ray-project/ray](https://seerepo.com/r/ray-project/ray): Ray is an AI compute engine. Ray consists of a core distributed runtime and a set of AI Libraries for accelerating ML workloads.

## Side by side

| | DiffSynth-Studio | ray |
|---|---|---|
| Size | 139,261 lines written, 308 code files | 1,531,664 lines written, 2,777 code files |
| Who writes it | 1.6% of its commits signed by AI. With Gemini CLI and Claude Code | 3.6% of its commits signed by AI. With Claude Code, Gemini CLI, GitHub Copilot, Cursor, and Codex |
| Activity | Last push November 9, 2026, 989 commits, 13,353 stars | Last push November 6, 2026, 32,373 commits, 44,213 stars |
| Tests | 1 test files | 2,168 test files. 9.7% 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.
