Quantization recipe _{(advanced, embedded in quantization_config.json)}

Setting	Value
Format	`EXL3`
Bits per weight	`5.0`
Head bits	`8`
Calibration rows	`250`
Codebook	`mul1`
Out‑scales	`always`
Parallel mode	`enabled`

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.
