Case Study: PyTorch achieves faster, more reliable open source CI/CD with CircleCI

PyTorch relies on CircleCI to manage 900+ open source contributors

PyTorch, an open source deep learning platform with nearly 100 core members and 900+ contributors, needed a reliable way to manage CI/CD at scale for its large community. Using CircleCI, the team had to support a consistent pull request and build process across hundreds of downstream research and commercial projects while keeping development moving quickly.

CircleCI helped PyTorch streamline its open source software delivery workflow by running builds in parallel across multiple instance types. This cut tutorial build times from four to six hours by 75%, reduced infrastructure overhead, and let the team focus more on the community and core research work rather than maintaining machines.
