## Exllama v2 Quantizations of Tess-2.0-Yi-34B-200K
Using turboderp's ExLlamaV2 v0.0.17 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/migtissera/Tess-2.0-Yi-34B-200K
| Branch | Bits | lm_head bits | VRAM (4k) | VRAM (16k) | VRAM (32k) | Description |
| ------ | ---- | ------------ | ---- | ---- | ---- | ----------- |
| [6_5](https://huggingface.co/bartowski/Tess-2.0-Yi-34B-200K-exl2/tree/6_5) | 6.5 | 8.0 | 28.9 GB | 31.6 GB | 35.6 GB | Near unquantized performance at vastly reduced size, **recommended**. |
| [4_25](https://huggingface.co/bartowski/Tess-2.0-Yi-34B-200K-exl2/tree/4_25) | 4.25 | 6.0 | 19.5 GB | 22.2 GB | 26.2 GB | GPTQ equivalent bits per weight, slightly higher quality. |
| [3_5](https://huggingface.co/bartowski/Tess-2.0-Yi-34B-200K-exl2/tree/3_5) | 3.5 | 6.0 | 16.5 GB | 19.2 GB | 23.2 GB | Lower quality, only use if you have to. |
| [3_0](https://huggingface.co/bartowski/Tess-2.0-Yi-34B-200K-exl2/tree/3_0) | 3.0 | 6.0 | 14.3 GB | 17.0 GB | 21.0 GB | Very low quality, usable with 16gb of VRAM. |
## Download instructions
With git:
```shell
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/Tess-2.0-Yi-34B-200K-exl2 Tess-2.0-Yi-34B-200K-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 `Tess-2.0-Yi-34B-200K-exl2`:
```shell
mkdir Tess-2.0-Yi-34B-200K-exl2
huggingface-cli download bartowski/Tess-2.0-Yi-34B-200K-exl2 --local-dir Tess-2.0-Yi-34B-200K-exl2 --local-dir-use-symlinks False
```
To download from a different branch, add the `--revision` parameter:
Linux:
```shell
mkdir Tess-2.0-Yi-34B-200K-exl2-6_5
huggingface-cli download bartowski/Tess-2.0-Yi-34B-200K-exl2 --revision 6_5 --local-dir Tess-2.0-Yi-34B-200K-exl2-6_5 --local-dir-use-symlinks False
```
Windows (which apparently doesn't like _ in folders sometimes?):
```shell
mkdir Tess-2.0-Yi-34B-200K-exl2-6.5
huggingface-cli download bartowski/Tess-2.0-Yi-34B-200K-exl2 --revision 6_5 --local-dir Tess-2.0-Yi-34B-200K-exl2-6.5 --local-dir-use-symlinks False
```
