Quantization methodology used

1. Generating the matrix:

$ llama-imatrix \
    -m Qwen3.8-27B-Q8_0.gguf \
    -f calib.txt \
    -o qwen3-27b.imatrix \
    -c 512

2. Generating the quantizations:

$ llama-quantize \
    --imatrix qwen3-27b.imatrix \
    Qwen3.8-27B-BF16-00001-of-00002.gguf \
    {output_name}.gguf \
    {quant_type} # list: https://github.com/charlie12345/ROCmFPX#which-format-should-i-pick
