Tess-7B-v1.4-exl2

Exllama v2 Quantizations of Tess-7B-v1.4

Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.0.10">turboderp's ExLlamaV2 v0.0.10</a> for quantization.

Each branch contains an individual bits per weight, with the main one containing only the meaurement.json for further conversions.

Conversion was done using wikitext-103-raw-v1-test.parquet as calibration dataset.

Default arguments used except when the bits per weight is above 6.0, at that point the lm_head layer is quantized at 8 bits per weight instead of the default 6.

To download the main (only useful if you only care about measurement.json) branch to a folder called Tess-7B-v1.4-exl2:

mkdir Tess-7B-v1.4-exl2
huggingface-cli download bartowski/Tess-7B-v1.4-exl2 --local-dir Tess-7B-v1.4-exl2 --local-dir-use-symlinks False

To download from a different branch, add the --revision parameter:

mkdir Tess-7B-v1.4-exl2
huggingface-cli download bartowski/Tess-7B-v1.4-exl2 --revision 4_0 --local-dir Tess-7B-v1.4-exl2 --local-dir-use-symlinks False
