=== Tested Models for B70 ===
=== Best-Fit Models for B70 ===


{| class="wikitable sortable" style="text-align:center;"
The B70 delivers the best performance with W4A8 quantized models.
! Model ID
 
! B70 loadable
The underlying rationale can be referenced from TechPowerUp’s spec data, and the listed models show solid performance.
! B70x1 tg128
 
! B70x2 tg128

The five options are important, especially <code>--chat-template-kwargs '{"reasoning_effort":"..."}'</code>.
The option <code>reasoning_effort</code> can be set to <code>xhigh</code>, <code>medium</code>, and <code>low</code>, but <code>xhigh</code> causes significant performance degradation.
* <code>--temp 1.0</code>
* <code>--top-p 0.95</code>
