709

1825

1826
+ <p><strong>For most use cases:</strong> Start with <code>all-MiniLM-L6-v2</code> (80MB) as-is. Only pursue custom pruning if you:</p>
1827
+ <ul style="margin-left: 2rem; margin-top: 0.5rem;">
1828
+ <li>Have very specific domain requirements</li>
1829
+ <li>Need <50MB models for edge deployment</li>
1830
+ <li>Have domain data for distillation</li>
1831
+ </ul>
1832
+ <p style="margin-top: 1rem;">The pre-trained 80MB model is already excellent for 95% of use cases!</p>
