For improved performance, download and enable a compatible [MTP speculative decoder](https://huggingface.co/models?search=inferencerlabs/deepseek-v4-flash-mtp-mlx).

#### Tested on an M3 Ultra 512 GiB RAM using [Inferencer app v1.11.7](https://inferencer.com)
<table style="border-collapse: collapse; border: none; text-align:left; margin-top:10px; margin-bottom:0px;">
  <tr><td><strong>Text inference</strong></td><td>~31 tokens/s @ 1000 tokens ~148.5 GiB</td></tr>
  <tr><td><strong>Text inference (with MTP)</strong></td><td>~37.3 tokens/s @ 1000 tokens ~152.9 GiB</td></tr>

<strong>Q9 typically achieves near lossless accuracy in our coding test</strong>

In this build, the 4-bit pre-quantized weights of the base model were repacked (rather than dequantized and re-quantized to 9-bit), as this approach performed slightly better in our initial coding tests. All remaining weights were quantized to 9-bit.
