| **SqueezeLLM** is a post-training quantization framework that incorporates a new method called Dense-and-Sparse Quantization to enable efficient LLM serving. | |
| **TLDR:** Deploying LLMs is difficult due to their large memory size. This can be addressed with reduced precision quantization. | |
| But a naive method hurts performance. We address this with a new Dense-and-Sparse Quantization method. | |
| Dense-and-Sparse splits weight matrices into two components: A dense component that can be heavily quantized without affecting model performance, | |
| as well as a sparse part that preserves sensitive and outlier parts of the weight matrices With this approach, | |
| we are able to serve larger models with smaller memory footprint, the same latency, and yet higher accuracy and quality. | |
