## Exllama v2 Quantizations of Llama-3-ChatQA-1.5-8B |
|
|
|
Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.0.20">turboderp's ExLlamaV2 v0.0.20</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. |
|
|

|
| [8_0](https://huggingface.co/bartowski/Llama-3-ChatQA-1.5-8B-exl2/tree/8_0) | 8.0 | 8.0 | 10.1 GB | 10.5 GB | 11.5 GB | 13.6 GB | Maximum quality that ExLlamaV2 can produce, near unquantized performance. | |
|
| [6_5](https://huggingface.co/bartowski/Llama-3-ChatQA-1.5-8B-exl2/tree/6_5) | 6.5 | 8.0 | 8.9 GB | 9.3 GB | 10.3 GB | 12.4 GB | Very similar to 8.0, good tradeoff of size vs performance, **recommended**. | |
|
| [5_0](https://huggingface.co/bartowski/Llama-3-ChatQA-1.5-8B-exl2/tree/5_0) | 5.0 | 6.0 | 7.7 GB | 8.1 GB | 9.1 GB | 11.2 GB | Slightly lower quality vs 6.5, but usable on 8GB cards. | |
|
| [4_25](https://huggingface.co/bartowski/Llama-3-ChatQA-1.5-8B-exl2/tree/4_25) | 4.25 | 6.0 | 7.0 GB | 7.4 GB | 8.4 GB | 10.5 GB | GPTQ equivalent bits per weight, slightly higher quality. | |
|
| [3_5](https://huggingface.co/bartowski/Llama-3-ChatQA-1.5-8B-exl2/tree/3_5) | 3.5 | 6.0 | 6.4 GB | 6.8 GB | 7.8 GB | 9.9 GB | Lower quality, only use if you have to. | |

## Download instructions |
|
|
|
With git: |
|
|
|
```shell |
|
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/Llama-3-ChatQA-1.5-8B-exl2 Llama-3-ChatQA-1.5-8B-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/Llama-3-ChatQA-1.5-8B-exl2 --revision 6_5 --local-dir Llama-3-ChatQA-1.5-8B-exl2-6_5 --local-dir-use-symlinks False |
|
``` |
|
|
|
Windows (which apparently doesn't like _ in folders sometimes?): |
|
|
|
```shell |
|
huggingface-cli download bartowski/Llama-3-ChatQA-1.5-8B-exl2 --revision 6_5 --local-dir Llama-3-ChatQA-1.5-8B-exl2-6.5 --local-dir-use-symlinks False |
|
``` |
