+Base model: [Qwen/Qwen3-4B](https://huggingface.co/Qwen/Qwen3-4B)
 
+<i>This model is quantized to 4-bit with a group size of 128.</i>
+<br>
+<i>Compared to earlier quantized versions, the new quantized model demonstrates better tokens/s efficiency. This improvement comes from setting desc_act=False in the quantization configuration.</i>
