# Step-3.7-Flash-9bit
See Step-3.7-Flash in action: [demonstration videos](https://youtube.com/xcreate)
   
#### Tested with an M3 Ultra 512 GiB using [Inferencer app v1.11.7](https://inferencer.com)
- Text Inference: ~36.1 tokens/s @ 1000 tokens ~206 GiB
- Vision Inference: ~31.4 tokens/s ~210.3 GiB

<ul>
<li style="margin:0;">Perplexity: Measures the confidence for predicting base tokens (lower is better)</li>
<li style="margin:0;">Token Accuracy: The percentage of correctly generated base tokens</li>
<li style="margin:0;">Missed Divergence: Measures severity of misses; how much the token was missed by</li>
