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.

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

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
