Experimental .GGUF quants for https://huggingface.co/google/gemma-2-9b-it accordingly to LCPP PR |
|
(based on b_3529 and now b_3565 for the newer ones) : https://github.com/ggerganov/llama.cpp/pull/8836 |
|
|
|
These experimental quant strategies revisiting Ikawrakow's work are displaying a slight decrease of perplexity, |
|
including per bpw (from 10%+ for the lowest quants to 0.x% for the highest ones). |
|
This is significant enough to encourage you folks to test them, and provide feedback if pertinent. |
|
|
|
The iMatrix I use is based on Group Merged V3 and enriched with a bit of French, |
|
a bit of Serbian, and a bit of Croatian languages. |
