## Exllama v2 Quantizations of LongAlign-13B-64k |
|
|
|
Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.0.12">turboderp's ExLlamaV2 v0.0.12</a> 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/THUDM/LongAlign-13B-64k |
|
|
|
No GQA - VRAM requirements will be higher |
|
|
|
| Branch | Bits | lm_head bits | VRAM (4k) | VRAM (16k) | Description | |
|
| ----- | ---- | ------- | ------ | ------ | ------------ | |
|
| [6_5](https://huggingface.co/Bartowski/LongAlign-13B-64k-exl2/tree/6_5) | 6.5 | 8.0 | 14.4 GB | 24.0 GB | Near unquantized performance at vastly reduced size, **recommended**. | |
|
| [5_0](https://huggingface.co/Bartowski/LongAlign-13B-64k-exl2/tree/5_0) | 5.0 | 6.0 | 12.1 GB | 21.7 GB | Slightly lower perplexity vs 6.5, can fit in 12 GB card with even lower context. | |
|
| [4_25](https://huggingface.co/Bartowski/LongAlign-13B-64k-exl2/tree/4_25) | 4.25 | 6.0 | 10.9 GB | 20.5 GB | GPTQ equivalent bits per weight. | |
|
| [3_75](https://huggingface.co/Bartowski/LongAlign-13B-64k-exl2/tree/3_75) | 3.75 | 6.0 | 10.1 GB | 19.7 GB | Lower quality but still generally usable. | |
|
| [3_0](https://huggingface.co/Bartowski/LongAlign-13B-64k-exl2/tree/3_0) | 3.0 | 6.0 | 9.1 GB | 18.7 GB | Very low quality, not recommended unless you have to. | |
|
|
|
VRAM requirements listed for both 4k context and 16k context since without GQA the differences are massive (9.6 GB) |

## Download instructions |
|
|
|
With git: |
|
|
|
```shell |
|
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/LongAlign-13B-64k-exl2 LongAlign-13B-64k-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 `LongAlign-13B-64k-exl2`: |
|
|
|
```shell |
|
mkdir LongAlign-13B-64k-exl2 |
|
huggingface-cli download bartowski/LongAlign-13B-64k-exl2 --local-dir LongAlign-13B-64k-exl2 --local-dir-use-symlinks False |
|
``` |
|
|
|
To download from a different branch, add the `--revision` parameter: |
|
|
|
Linux: |
|
|
|
```shell |
|
mkdir LongAlign-13B-64k-exl2-6_5 |
|
huggingface-cli download bartowski/LongAlign-13B-64k-exl2 --revision 6_5 --local-dir LongAlign-13B-64k-exl2-6_5 --local-dir-use-symlinks False |
|
``` |
|
|
|
Windows (which apparently doesn't like _ in folders sometimes?): |
|
|
|
```shell |
|
mkdir LongAlign-13B-64k-exl2-6.5 |
|
huggingface-cli download bartowski/LongAlign-13B-64k-exl2 --revision 6_5 --local-dir LongAlign-13B-64k-exl2-6.5 --local-dir-use-symlinks False |
|
``` |
