Block Rotation is All You Need for MXFP4 Quantization
A recent study highlights the potential of block rotation for MXFP4 quantization, a new FP4 format that could significantly enhance the efficiency of large language models (LLMs). As these models grow in size, the costs associated with memory and computation become a major concern. Post-training quantization (PTQ) offers a solution, but achieving accurate W4A4 quantization has been challenging. This breakthrough could pave the way for more sustainable AI technologies, making it easier to deploy powerful models without the hefty resource demands.
