## Exllama v2 Quantizations of openchat-3.5-0106-gemma
Using turboderp's ExLlamaV2 v0.0.15 for quantization.
The "main" branch only contains the measurement.json, download one of the other branches for the model (see below)
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/openchat/openchat-3.5-0106-gemma
No GQA - VRAM requirements will be higher
| Branch | Bits | lm_head bits | Size (4k) | Size (16k) | Description |
| -------------------------------------------------------------- | ---- | ------------ | --------- | ---------- | ----------- |
| [8_0](https://huggingface.co/bartowski/openchat-3.5-0106-gemma-exl2/tree/8_0) | 8.0 | 8.0 | 14.0 GB | 19.4 GB | Maximum quality that ExLlamaV2 can produce, near unquantized performance. |
| [6_5](https://huggingface.co/bartowski/openchat-3.5-0106-gemma-exl2/tree/6_5) | 6.5 | 8.0 | 12.5 GB | 17.9 GB | Near unquantized performance at vastly reduced size, **recommended**. |
| [5_0](https://huggingface.co/bartowski/openchat-3.5-0106-gemma-exl2/tree/5_0) | 5.0 | 6.0 | 10.9 GB | 16.3 GB | Slightly lower quality vs 6.5, but usable on 8GB cards with 4k context. |
| [4_25](https://huggingface.co/bartowski/openchat-3.5-0106-gemma-exl2/tree/4_25) | 4.25 | 6.0 | 10.2 GB | 15.7 GB | GPTQ equivalent bits per weight. |
| [3_5](https://huggingface.co/bartowski/openchat-3.5-0106-gemma-exl2/tree/3_5) | 3.5 | 6.0 | 9.5 GB | 14.9 GB | Lower quality, not recommended. |
## Download instructions
With git:
```shell
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/openchat-3.5-0106-gemma-exl2 openchat-3.5-0106-gemma-exl2-6_5
```
With huggingface hub (credit to TheBloke for instructions):
```shell
pip3 install huggingface-hub
```
To download the `main` (only useful if you only care about measurement.json) branch to a folder called `openchat-3.5-0106-gemma-exl2`:
```shell
mkdir openchat-3.5-0106-gemma-exl2
huggingface-cli download bartowski/openchat-3.5-0106-gemma-exl2 --local-dir openchat-3.5-0106-gemma-exl2 --local-dir-use-symlinks False
```
To download from a different branch, add the `--revision` parameter:
Linux:
```shell
mkdir openchat-3.5-0106-gemma-exl2-6_5
huggingface-cli download bartowski/openchat-3.5-0106-gemma-exl2 --revision 6_5 --local-dir openchat-3.5-0106-gemma-exl2-6_5 --local-dir-use-symlinks False
```
Windows (which apparently doesn't like _ in folders sometimes?):
```shell
mkdir openchat-3.5-0106-gemma-exl2-6.5
huggingface-cli download bartowski/openchat-3.5-0106-gemma-exl2 --revision 6_5 --local-dir openchat-3.5-0106-gemma-exl2-6.5 --local-dir-use-symlinks False
```
