What's changed

Safetensors 0.8.0 brings direct to Metal loading on Apple Silicon, GIL-free serialization, broader hardware and dtype coverage, and a stronger Python API.

Breaking

The serialize and serialize_file functions now release the GIL during writes, enabling true multithreaded saves from Python. Their input contract has also changed: tensor metadata is now passed via a TensorSpec class (exported from safetensors) instead of plain dicts, making API more explicit and robust to misinputs. This is a breaking change for anyone calling the low-level serialize / serialize_file API directly; the high-level wrappers (safetensors.torch, safetensors.numpy, safetensors.paddle) are updated internally and their public API is unchanged.

The minimum supported Python version is now 3.10 (was 3.9). Python 3.9 reached end-of-life in October 2025.

TensorIndexer::Narrow now carries a step: NonZeroUsize parameter, so a slice is now start:stop:step. This is a fix as this silent error was hidden behind the Storage::Torch variant which offloaded slicing logic to torch directly.

CI

On the platform side, this release adds Windows ARM64 wheel builds, riscv64 Linux wheels, and CI has been hardened with pinned GitHub Actions SHAs.

Also dropped the anaconda CI we had as there's already an automatic tracker via conda-forge.

New features
  • Direct MPS load on Apple Silicon: tensors are directly loaded in an MTLBuffer and handed to the frameworks that support it (only torch atm) via DLPack, skipping needless copies.
  • New backend parameter introduced, for the addition of the pread backend. We now support loading files via pread(2) syscall instead of just mmap. Useful for specific archs/platforms.
  • get_slice now handles ellipsis [...] and strided slices [:, ::8] wherever safetensors does the slicing itself (pread for any framework, MPS, and mmap outside torch/paddle), which silently dropped the step or rejected ... before.
  • MUSA device support for MooreThreads GPUs.
  • New dtype support includes float8_e4m3fnuz and float8_e5m2fnuz (AMD FNUZ FP8 formats).
  • The reader is now explicitly lenient about leading whitespace in the JSON header, which keeps the door open for future page-aligned writes.
Improvements/perf
  • File writes on macOS now use F_NOCACHE for direct I/O, yielding roughly 30% faster save_file on Apple Silicon.
  • The packaging dependency has been dropped from the [torch] extra, replaced by a simple hasattr probe for efficiency.
