Nous-Capybara-34B and Tess-M-Creative-v1.0 merged, then quantized with exllamav2 on 200 rows (400K tokens) on a long Vicuna format chat, a sci fi story and a fantasy story. This should hopefully yield better chat performance than the default wikitext quantization. |
|
|
|
Quantized to 4bpw, enough for **~47K context on a 24GB GPU.** |
|
|
|
The following merge config was used: |
|
``` |
|
models: |
|
- model: /home/alpha/Storage/Models/Raw/larryvrh_Yi-34B-200K-Llamafied |
|
# no parameters necessary for base model |
|
- model: /home/alpha/Storage/Models/Raw/migtissera_Tess-M-v1.0 |
|

|

base_model: //home/alpha/Storage/Models/Raw/larryvrh_Yi-34B-200K-Llamafied |

``` |
|

|
First exllama quantization pass: |
|
``` |
|
python convert.py --in_dir /home/alpha/FastModels/Capybara-Tess-Yi-34B-200K -o /home/alpha/FastModels/Capybara-Tess-Yi-34B-200K-exl2 -om /home/alpha/FastModels/capytessmes.json --cal_dataset /home/alpha/Documents/smol.parquet -l 2048 -r 80 -ml 2048 -mr 40 -gr 40 -ss 4096 -nr -b 3.5 -hb 6 |
|
``` |
|
|
|
Second exllama quantization pass: |
|
``` |
|
python convert.py --in_dir /home/alpha/FastModels/Capybara-Tess-Yi-34B-200K -o /home/alpha/FastModels/Capybara-Tess-Yi-34B-200K-exl2 -m /home/alpha/FastModels/capytessmes.json --cal_dataset /home/alpha/Documents/medium.parquet -l 2048 -r 200 -ml 2048 -mr 40 -gr 200 -ss 4096 -b 3.1 -hb 6 -cf /home/alpha/FastModels/Capybara-Tess-Yi-34B-200K-exl2-31bpw -nr |
|
``` |
|
|
|
Both models have Vicuna syntax, so: |
|
|
|
# Prompt Format: |
|
|
|
``` |
|
SYSTEM: ... |
|
USER: ... |
|
ASSISTANT: ... |
|
``` |
|
Stop token: `</s>` |
