Exllama v2 Quantizations of LongAlign-13B-64k
Using turboderp's ExLlamaV2 v0.0.12 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 | 6.5 | 8.0 | 14.4 GB | 24.0 GB | Near unquantized performance at vastly reduced size, recommended. |
| 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 | 4.25 | 6.0 | 10.9 GB | 20.5 GB | GPTQ equivalent bits per weight. |
| 3_75 | 3.75 | 6.0 | 10.1 GB | 19.7 GB | Lower quality but still generally usable. |
| 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:
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):
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:
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:
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?):
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
