About
bitsandbytes is a powerful library designed to make large language models (LLMs) more accessible through k-bit quantization for PyTorch. It significantly reduces memory consumption during both inference and training, allowing for more efficient use of computational resources. The library provides three core features: 8-bit optimizers that use block-wise quantization to maintain 32-bit performance with reduced memory, LLM.int8() for 8-bit quantization enabling large language model inference with half the memory and no performance degradation, and QLoRA for 4-bit quantization, which facilitates LLM training with memory-saving techniques without compromising performance. It includes quantization primitives for 8-bit and 4-bit operations, along with 8-bit optimizers, making it an essential tool for developers working with large-scale AI models.
