| Branch | Bits | lm_head bits | VRAM (4k) | VRAM (16k) | VRAM (32k) | Description |
|---|---|---|---|---|---|---|
| 8_0 | 8.0 | 8.0 | 8.4 GB | 9.8 GB | 11.8 GB | Maximum quality that ExLlamaV2 can produce, near unquantized performance. |
| 6_5 | 6.5 | 8.0 | 7.2 GB | 8.6 GB | 10.6 GB | Very similar to 8.0, good tradeoff of size vs performance, recommended. |

To download the main (only useful if you only care about measurement.json) branch to a folder called Nexus-IKM-Mistral-7B-exl2:
mkdir Nexus-IKM-Mistral-7B-exl2
huggingface-cli download bartowski/Nexus-IKM-Mistral-7B-exl2 --local-dir Nexus-IKM-Mistral-7B-exl2 --local-dir-use-symlinks False

Linux:
mkdir Nexus-IKM-Mistral-7B-exl2-6_5
huggingface-cli download bartowski/Nexus-IKM-Mistral-7B-exl2 --revision 6_5 --local-dir Nexus-IKM-Mistral-7B-exl2-6_5 --local-dir-use-symlinks False
Windows (which apparently doesn't like _ in folders sometimes?):
mkdir Nexus-IKM-Mistral-7B-exl2-6.5
huggingface-cli download bartowski/Nexus-IKM-Mistral-7B-exl2 --revision 6_5 --local-dir Nexus-IKM-Mistral-7B-exl2-6.5 --local-dir-use-symlinks False
