  # BitBLAS
  
  BitBLAS is a library to support mixed-precision BLAS operations on GPUs, for example, the $W_{wdtype}A_{adtype}$ mixed-precision matrix multiplication where $C_{cdtype}[M, N] = A_{adtype}[M, K] \times W_{wdtype}[N, K]$.
  BitBLAS aims to support efficient mixed-precision DNN model deployment, especially the $W_{wdtype}A_{adtype}$ quantization in large language models (LLMs), for example, the $W_{UINT4}A_{FP16}$ in GPTQ, the $W_{INT2}A_{FP16}$ in BitDistiller, the $W_{INT2}A_{INT8}$ in BitNet-b1.58. BitBLAS is based on techniques from our paper "Ladder: Enabling Efficient Low-Precision Deep Learning Computing through Hardware-aware Tensor Transformation" at OSDI'24.

  # BitBLAS: High-Performance Mixed-Precision BLAS for Quantized LLM Inference
  
  BitBLAS is a specialized library for **efficient mixed-precision BLAS operations on GPUs**, specifically designed to accelerate the deployment of **quantized Large Language Models (LLMs)**. Unlike general-purpose BLAS libraries or broader ML frameworks, BitBLAS focuses on optimizing critical $W_{wdtype}A_{adtype}$ matrix multiplications (e.g., FP16xINT4, INT8xINT2) essential for low-bit LLM inference. It leverages techniques from our OSDI'24 paper 'Ladder: Enabling Efficient Low-Precision Deep Learning Computing through Hardware-aware Tensor Transformation'.
