bitsandbytes v0.50.0 is out, with 4-bit LLM inference now up to 4× faster on NVIDIA GPUs.
The release is broader than just CUDA: AMD ROCm gets a new fast 4-bit path and is now stable, Windows wheels are included, and support expands to more GPUs. The maintainer frames it as making low-bit inference both faster and easier to install.
