# ColossalAI vs open_clip

ColossalAI and open_clip share 7 technologies: Hugging Face, tiktoken, torch, transformers, timm, safetensors, and torchvision. Both are written in Python.

- [hpcaitech/ColossalAI](https://seerepo.com/r/hpcaitech/ColossalAI): Making large AI models cheaper, faster and more accessible
- [mlfoundations/open_clip](https://seerepo.com/r/mlfoundations/open_clip): An open source implementation of CLIP.

- 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.
