**SqueezeLLM** is a post-training quantization framework that incorporates a new method called Dense-and-Sparse Quantization to enable efficient LLM serving.
|
2 |
+
|
3 |
+
**TLDR:** Deploying LLMs is difficult due to their large memory size. This can be addressed with reduced precision quantization.
|
4 |
+
But a naive method hurts performance. We address this with a new Dense-and-Sparse Quantization method.
|
5 |
+
Dense-and-Sparse splits weight matrices into two components: A dense component that can be heavily quantized without affecting model performance,
|
6 |
+
as well as a sparse part that preserves sensitive and outlier parts of the weight matrices With this approach,
|
7 |
+
we are able to serve larger models with smaller memory footprint, the same latency, and yet higher accuracy and quality.
