PROUDLY PRESENTS

experiment_1_8b-iMat-GGUF

Quantization Note: Use repetition penalty (--repeat-penalty on llama.cpp) of ~1.15 for best results

Quantized from fp16 with love.

Weighted quantizations were created using fp16 GGUF and groups_merged-enhancedV2-TurboMini.txt in 189 chunks and n_ctx=512
This method of calculating the importance matrix showed improvements in some areas for Mistral 7b and Llama3 8b models, see above post for details
The enhancedv2-turbomini file appends snippets from turboderp's calibration data to the standard groups_merged.txt file

For a brief rundown of iMatrix quant performance please see this PR

All quants are verified working prior to uploading to repo for your safety and convenience.

UNTESTED, probably unfit for human consumption
