Branch	Bits	lm_head bits	VRAM (4k)	VRAM (16k)	Description
8_0	8.0	8.0	16.8 GB	26.2 GB	Near unquantized performance at vastly reduced size, recommended.
6_5	6.5	8.0	14.4 GB	24.0 GB	Near unquantized performance at vastly reduced size, recommended.
5_0	5.0	6.0	12.1 GB	21.7 GB	Slightly lower perplexity vs 6.5, can fit in 12 GB card with even lower context.
4_25	4.25	6.0	10.9 GB	20.5 GB	GPTQ equivalent bits per weight.
3_75	3.75	6.0	10.1 GB	19.7 GB	Lower quality but still generally usable.
3_0	3.0	6.0	9.1 GB	18.7 GB	Very low quality, not recommended unless you have to.

VRAM requirements listed for both 4k context and 16k context since without GQA the differences are massive (9.6 GB)

Download instructions

With git:

git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/OpenHermes-2.5-Code-290k-13B-exl2 OpenHermes-2.5-Code-290k-13B-exl2-6_5

With huggingface hub (credit to TheBloke for instructions):

pip3 install huggingface-hub

To download the main (only useful if you only care about measurement.json) branch to a folder called OpenHermes-2.5-Code-290k-13B-exl2:

shell

mkdir OpenHermes-2.5-Code-290k-13B-exl2
huggingface-cli download bartowski/OpenHermes-2.5-Code-290k-13B-exl2 --local-dir OpenHermes-2.5-Code-290k-13B-exl2 --local-dir-use-symlinks False

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

Linux:

shell

mkdir OpenHermes-2.5-Code-290k-13B-exl2-6_5
huggingface-cli download bartowski/OpenHermes-2.5-Code-290k-13B-exl2 --revision 6_5 --local-dir OpenHermes-2.5-Code-290k-13B-exl2-6_5 --local-dir-use-symlinks False

Windows (which apparently doesn't like _ in folders sometimes?):

shell

mkdir OpenHermes-2.5-Code-290k-13B-exl2-6.5
huggingface-cli download bartowski/OpenHermes-2.5-Code-290k-13B-exl2 --revision 6_5 --local-dir OpenHermes-2.5-Code-290k-13B-exl2-6.5 --local-dir-use-symlinks False
