To download the main (only useful if you only care about measurement.json) branch to a folder called starchat2-15b-v0.1-exl2:

mkdir starchat2-15b-v0.1-exl2
huggingface-cli download bartowski/starchat2-15b-v0.1-exl2 --local-dir starchat2-15b-v0.1-exl2 --local-dir-use-symlinks False

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

Linux:

mkdir starchat2-15b-v0.1-exl2-6_5
huggingface-cli download bartowski/starchat2-15b-v0.1-exl2 --revision 6_5 --local-dir starchat2-15b-v0.1-exl2-6_5 --local-dir-use-symlinks False

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

mkdir starchat2-15b-v0.1-exl2-6.5
huggingface-cli download bartowski/starchat2-15b-v0.1-exl2 --revision 6_5 --local-dir starchat2-15b-v0.1-exl2-6.5 --local-dir-use-symlinks False
