## Exllama v2 Quantizations of SuperNova-Medius
Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.2.3">turboderp's ExLlamaV2 v0.2.3</a> for quantization.
<b>The "main" branch only contains the measurement.json, download one of the other branches for the model (see below)</b>
Each branch contains an individual bits per weight, with the main one containing only the meaurement.json for further conversions.
Original model: https://huggingface.co/arcee-ai/SuperNova-Medius
## Prompt format
```
<|im_start|>system
{system_prompt}<|im_end|>
<|im_start|>user
{prompt}<|im_end|>
<|im_start|>assistant
```
## Available sizes
| Branch | Bits | lm_head bits | VRAM (4k) | VRAM (16k) | Description |

| [3_5](https://huggingface.co/bartowski/SuperNova-Medius-exl2/tree/3_5) | 3.5 | 6.0 | 8.7 GB | 11.5 GB | Lower quality, not recommended. |
| [3_0](https://huggingface.co/bartowski/SuperNova-Medius-exl2/tree/3_0) | 3.0 | 6.0 | 7.8 GB | 10.5 GB | Low quality, not recommended. |
## Download instructions
With git:
```shell
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/SuperNova-Medius-exl2 SuperNova-Medius-exl2-6_5
```
With huggingface hub (credit to TheBloke for instructions):
```shell
pip3 install huggingface-hub
```
To download a specific branch, use the `--revision` parameter. For example, to download the 6.5 bpw branch:
Linux:
```shell
huggingface-cli download bartowski/SuperNova-Medius-exl2 --revision 6_5 --local-dir SuperNova-Medius-exl2-6_5
```
Windows (which apparently doesn't like _ in folders sometimes?):
```shell
huggingface-cli download bartowski/SuperNova-Medius-exl2 --revision 6_5 --local-dir SuperNova-Medius-exl2-6.5
```
