Branch	Bits	lm_head bits	Size (4k)	Size (16k)	Description
8_0	8.0	8.0	9.4 GB	15.6 GB	Maximum quality that ExLlamaV2 can produce, near unquantized performance.
6_5	6.5	8.0	8.6 GB	14.8 GB	Near unquantized performance at vastly reduced size, recommended.
5_0	5.0	6.0	7.2 GB	13.4 GB	Slightly lower quality vs 6.5, but usable on 8GB cards with 4k context.
4_25	4.25	6.0	6.5 GB	12.7 GB	GPTQ equivalent bits per weight.
3_5	3.5	6.0	5.9 GB	12.1 GB	Lower quality, not recommended.

Download instructions

With git:

shell

git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/Chat2DB-SQL-7B-exl2 Chat2DB-SQL-7B-exl2-6_5

With huggingface hub (credit to TheBloke for instructions):

shell

pip3 install huggingface-hub

To download the main (only useful if you only care about measurement.json) branch to a folder called Chat2DB-SQL-7B-exl2:

shell

mkdir Chat2DB-SQL-7B-exl2
huggingface-cli download bartowski/Chat2DB-SQL-7B-exl2 --local-dir Chat2DB-SQL-7B-exl2 --local-dir-use-symlinks False

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

Linux:

shell

mkdir Chat2DB-SQL-7B-exl2-6_5
huggingface-cli download bartowski/Chat2DB-SQL-7B-exl2 --revision 6_5 --local-dir Chat2DB-SQL-7B-exl2-6_5 --local-dir-use-symlinks False

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

shell

mkdir Chat2DB-SQL-7B-exl2-6.5
huggingface-cli download bartowski/Chat2DB-SQL-7B-exl2 --revision 6_5 --local-dir Chat2DB-SQL-7B-exl2-6.5 --local-dir-use-symlinks False
