|---|---|
| Format | EXL3 |
| Bits per weight | 4.5 |
| 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.
