As AI model development accelerates, security risks in the production pipeline inherently increase, necessitating secure, high-performance formats that can keep pace with deployment. Safetensors joining the Foundation minimizes security risks associated with model architectures and execution, providing developers with a trusted path to production.<\/p>\n
Safetensors is one of the most widely used metadata formats for model distribution.<\/p>\n
“Safetensors’ contribution to the PyTorch Foundation is an important step towards scaling production-grade AI models,” said Mark Collier, Executive Director of the PyTorch Foundation. “Safetensors ensures secure model distribution and de-risks code execution, all while offering significant speed across complex computing architectures. For security, Safetensors is a crucial piece of the open source AI stack that will drive fast, secure, and technically advanced AI.”<\/p>\n Developed and maintained by Hugging Face, Safetensors has become one of the most widely adopted tensor serialization formats in the open source (machine learning) ML ecosystem. In previous pickle formats, opportunities existed for developers, or bad actors, to execute arbitrary, untrusted code within model files when shared. Acting as a table of contents for an AI model’s data, Safetensors prevents arbitrary code execution and is now one of the most widely used metadata formats for model distribution.<\/p>\n Developers and contributors interested in participating in the PyTorch project ecosystem are encouraged to join the community onsite at upcoming events like PyTorch Conference China<\/a>\u00a0(Shanghai, September 8-9) and PyTorch Conference North America<\/a>\u00a0(San Jose, October 20-21).<\/p>\n Supporting Quotes<\/p>\n Safetensors joining the PyTorch Foundation is an important step towards using a safe serialization format everywhere by default.<\/p>\n The new ecosystem and exposure the library will gain from this move will solidify its security guarantees and usability.\u00a0Safetensors is a well-established project, adopted by the ecosystem at large, but we’re still convinced we’re at the very beginning of its lifecycle: the coming months will see significant growth, and we couldn’t think of a better home for that next chapter than the PyTorch Foundation. “Safetensors joining the PyTorch Foundation promises safer, more interoperable packaging for model artifacts. The project has become a de facto standard for open-weight model distribution by halting risk associated with arbitrary code execution while also supporting fast, practical loading workflows. Together with Helion, these contributions to the Foundation solidify the technical future for open source AI.” About the PyTorch Foundation About the Linux Foundation The Linux Foundation has registered trademarks and uses trademarks.
