Amethyst 13B Mistral - EXL2 - 2.2 bpw

• Model creator: Undi
• Original model: Amethyst 13B Mistral

Description

• 2.2 bits per weight.
• I think it's not very usable, seems rather nonsensical compared to 3 bpw.
• I don't think exllamav2's current conversion script is able to convert to anything below ~2.18 bpw, at least not with the methods I tried.

I converted the model using the convert.py script from the exllamav2 repo:
https://github.com/turboderp/exllamav2
Its documentation:

I used the WikiText-2-v1 dataset for calibration:
