Caffe2 is an open-source deep learning framework presented as lightweight, modular, and scalable. Its website provides documentation, tutorials, API references, and a blog to help users learn about the framework and access technical information. The project also invites community participation through GitHub, where visitors can contribute or file an issue, and links to social channels including Facebook and Twitter.

Caffe2’s APIs are being deprecated. The site explains that Caffe2 is now part of PyTorch and that its existing APIs will continue to work, while encouraging users to adopt PyTorch APIs instead. It directs visitors to further information and to pytorch.org for the current project destination. This makes Caffe2 relevant both to developers maintaining existing work that uses its APIs and to those seeking guidance on moving toward PyTorch. The brand’s current online presence serves as an informational and transition resource, combining legacy framework materials with notices about its relationship to PyTorch and routes for community engagement.
