What is PySyft?
PySyft is a tool where data scientists submit computations and data owners run them on their own private data, working through cloud storage that organizations already use, such as Google Drive and Microsoft 365. Private data never leaves the owner's computer, and only approved results are shared. Its developer OpenMined is a nonprofit community building Syft, a federated AI network that coordinates secure computation across silos without moving data. It also provides tutorials such as double-blind LLM evaluation inside an enclave.
- Private data stays on the owner's device and only approved results are shared
- Transport-agnostic (currently Google Drive)
- Offline-first, syncs on reconnection
- Explicit approval per collaborator
- Isolated execution in a sandboxed Python virtual environment
- Separate sharing of mock data and real data
Who uses PySyft and for what
- External auditors auditing AI without seeing the model or user data
- Evaluating a private model on a private benchmark (double-blind)
- Collaborative genomics research without pooling raw data
