# Lyra4-Gutenberg-12B - EXL2 8bpw max

This is a 8bpw EXL2 quant of [nbeerbower/Lyra4-Gutenberg-12B](https://huggingface.co/nbeerbower/Lyra4-Gutenberg-12B)

This quant was made using exllamav2-0.2.1 with default dataset. I used a slightly modified quantization script to force use of highest bpw methods for all layers in the model (which is usually "1:8b_128g s4") to ensure max quality.

I also added a small fix in config file to set max default context at 128k as original Mistral-Nemo should have.

I tested this quant shortly in some random RPs (including ones over 8k context) and it seems to work fine.

## Prompt Templates

Uses ChatML or modified mistral format like mentioned in original Lyra v4. I tested it with ChatML.
