Safetensors
Fast and safe tensor serialization format by Hugging Face.
About
Safetensors by Hugging Face is a file format for storing tensors safely and quickly. Unlike Python pickle it cannot execute arbitrary code on load, and its layout supports zero-copy, memory-mapped reads for fast loading. It is now the default format for models distributed on the Hugging Face Hub, with Python and Rust implementations. Released under the Apache 2.0 license.
