#### Tested on a M3 Ultra 512GB RAM using [Inferencer app v1.10.6](https://inferencer.com)
- Single inference ~49.6 tokens/s @ 1000 tokens
- Batched inference ~ total tokens/s across five inferences
- Memory usage: ~67 GiB

<ul style="margin-top:8px;">
<li><strong>Perplexity:</strong> Measures the confidence for predicting base tokens (lower is better)</li>
<li><strong>Token Accuracy:</strong> The percentage of correctly generated base tokens</li>
<li><strong>Missed Divergence:</strong> Measures severity of misses; how much the token was missed by</li>
</ul>
