What this trail covers

Safetensors has joined the PyTorch Foundation, becoming a foundation-hosted project under the Linux Foundation. This move ensures vendor-neutral governance and community ownership. Future developments include device-aware loading/saving (direct to CUDA, ROCm), first-class APIs for Tensor Parallel and Pipeline Parallel loading, and formal support for FP8, block-quantized formats (GPTQ, AWQ), and sub-byte integer types.
