+### 3. Model Compression - 3x Inference Speed Up!
 
 We just added model compression based on block-wise quantization based model compression. Which can further **speed up the inference speed** for up to **3x** , with **almost ignorable accuracy loss!** (see more performance evaluation and why we use block-wise quantization in [this paper](https://arxiv.org/abs/2212.09720))
