<details> <summary><b>Quantization recipe</b> &nbsp;_{(advanced, embedded in <code>quantization_config.json</code>)}</summary> <br/>

The codebook is recorded in the weights, so loaders pick it up with no configuration. mul1 needs ExLlamaV3 v0.0.3 or newer; an older build ignores the marker and decodes the weights with the wrong codebook.

Loaded automatically by every ExLlamaV3 loader; reproduced here for searchability.
