What each one is
PyTorch
PyTorch is the deep-learning framework behind most of the models in this directory. If you train anything, you almost certainly train it here.
- The default in research and increasingly in production
- Enormous ecosystem, from Transformers to vLLM
- Eager execution makes debugging bearable
CVAT
CVAT is the professional annotation tool for video and images — bounding boxes, polygons, skeletons, with interpolation across frames.
- Interpolation makes video annotation bearable
- Automatic annotation with your own models
- Used by large annotation teams
Key differences
PyTorch is deep learning framework, while CVAT is video & image annotation. Their licenses differ (NOASSERTION vs MIT), which matters if you ship a commercial product. In short, PyTorch fits anyone training or fine-tuning a model, and CVAT fits computer vision datasets, especially video.
Which should you choose?
Choose PyTorch for anyone training or fine-tuning a model. Choose CVAT for computer vision datasets, especially video.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
Frequently asked questions
Is PyTorch or CVAT easier to use?
Both sit at a similar level (Intermediate). Your choice should come down to fit rather than difficulty.
Are PyTorch and CVAT free?
PyTorch is free and open source (NOASSERTION), and CVAT is free and open source (MIT). Neither charges for the core software.
Can I run PyTorch and CVAT locally?
PyTorch: yes · CVAT: yes. Both can be used without sending your data to a third-party cloud where their setup allows.
