anaconda.org: bitsandbytes

bitsandbytes is a library for efficient deep learning that enables 8-bit and 4-bit quantization for reduced memory usage and faster inference. It provides 8-bit optimizers for memory-efficient training, LLM.int8() for 8-bit matrix multiplication, and QLoRA for 4-bit quantization. The library is designed to work seamlessly with PyTorch and integrates with the Hugging Face ecosystem for large language model fine-tuning.
