## Exllama v2 Quantizations of OpenHermes-2.5-neural-chat-7b-v3-1-7B

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.

## Download instructions

With git:

```shell
git clone --single-branch --branch 4_0 https://huggingface.co/bartowski/OpenHermes-2.5-neural-chat-7b-v3-1-7B-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 `OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2`:

```shell
mkdir OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2
huggingface-cli download bartowski/OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2 --local-dir OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2 --local-dir-use-symlinks False
```

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

```shell
mkdir OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2
huggingface-cli download bartowski/OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2 --revision 4_0 --local-dir OpenHermes-2.5-neural-chat-7b-v3-1-7B-exl2 --local-dir-use-symlinks False
```
