Safetensors Project Joining the PyTorch Foundation

Published 2026-04-17AI Infrastructure and ComputeMedium⭐ Timeline Candidate

Summary

Hugging Face has announced that Safetensors, its open-source safe tensor serialization format, is being donated to and joining the PyTorch Foundation. Safetensors was created as a secure and efficient alternative to Python's pickle-based serialization, which has long been associated with security risks including arbitrary code execution when loading untrusted model files. The format has become widely adopted across the AI ecosystem for storing and distributing model weights. By moving Safetenso
