Using turboderp's ExLlamaV2 v0.0.12 for quantization.

Branch Bits lm_head bits Size Description
8_0 8.0 8.0 9.8 GB Maximum quality that ExLlamaV2 can produce, near unquantized performance.
6_5 6.5 8.0 8.6 GB Very similar to 8.0, good tradeoff of size vs performance, recommended.
5_0 5.0 6.0 7.4 GB Slightly lower quality vs 6.5, but usable on 8GB cards.
4_25 4.25 6.0 6.7 GB GPTQ equivalent bits per weight, slightly higher quality.
3_5 3.5 6.0 6.1 GB Lower quality, only use if you have to.

All VRAM requirements estimated from 16k context. For 32k context add ~2 GB.

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

mkdir Orca-Hermes-7B-slerp-exl2
huggingface-cli download bartowski/Orca-Hermes-7B-slerp-exl2 --local-dir Orca-Hermes-7B-slerp-exl2 --local-dir-use-symlinks False

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


mkdir Orca-Hermes-7B-slerp-exl2-6_5
huggingface-cli download bartowski/Orca-Hermes-7B-slerp-exl2 --revision 6_5 --local-dir Orca-Hermes-7B-slerp-exl2-6_5 --local-dir-use-symlinks False

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

mkdir Orca-Hermes-7B-slerp-exl2-6.5
huggingface-cli download bartowski/Orca-Hermes-7B-slerp-exl2 --revision 6_5 --local-dir Orca-Hermes-7B-slerp-exl2-6.5 --local-dir-use-symlinks False
