About this paper
Engineers can leverage LLM.int8() to reduce memory requirements and efficiently run large language models without performance degradation, even at scales exceeding billions of parameters. The method incorporates vector-wise quantization and mixed-precision decomposition to maintain full 16-bit performance in perplexity and zeroshot accuracy across large models, demonstrating significant memory savings and modest speedups for inference.
