## Exllama v2 Quantizations of Orca-2-7B-16k

Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.0.9">turboderp's ExLlamaV2 v0.0.9</a> for quantization.

Each branch contains an individual bits per weight, with the main one containing only the meaurement.json for further conversions.

Conversion was done using wikitext-103-raw-v1-test.parquet as calibration dataset.

Default arguments used except when the bits per weight is above 6.0, at that point the lm_head layer is quantized at 8 bits per weight instead of the default 6.

Original model: https://huggingface.co/NurtureAI/Orca-2-7B-16k
 
<a href="https://huggingface.co/bartowski/Orca-2-7B-16k-exl2/tree/4_0">4.0 bits per weight</a>
 
<a href="https://huggingface.co/bartowski/Orca-2-7B-16k-exl2/tree/5_0">5.0 bits per weight</a>
 
<a href="https://huggingface.co/bartowski/Orca-2-7B-16k-exl2/tree/6_0">6.0 bits per weight</a>
 
<a href="https://huggingface.co/bartowski/Orca-2-7B-16k-exl2/tree/8_0">8.0 bits per weight</a>

## Download instructions

With git:

```shell
git clone --single-branch --branch 4_0 https://huggingface.co/bartowski/Orca-2-7B-16k-exl2
```

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 `Orca-2-7B-16k-exl2`:

```shell
mkdir Orca-2-7B-16k-exl2
huggingface-cli download bartowski/Orca-2-7B-16k-exl2 --local-dir Orca-2-7B-16k-exl2 --local-dir-use-symlinks False
```

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

```shell
mkdir Orca-2-7B-16k-exl2
huggingface-cli download bartowski/Orca-2-7B-16k-exl2 --revision 4_0 --local-dir Orca-2-7B-16k-exl2 --local-dir-use-symlinks False
```
