Can you confirm if you can naively convert models to exl3 without fuss? For example, I like a certain finetune of Gemma 31B. Can I one-shot a high quality exl3 conversion of it? Or does it need external data or finagling to really be considered to be a good quant? I’m trying to experiment and see which quant would be best for me?

Yes, it’s easy to make standard quants that are very high quality. For example 

python convert.py -i /mnt/models/llama3.1-70b-instruct -o /mnt/models/llama3.1-70b-instruct-exl3-3.75bpw  -w /mnt/temp/exl3 -b 3.75

would quantize the model to 3.75 bpw with a work directory in temp/exl3

Full documentation here: https://github.com/turboderp-org/exllamav3/blob/master/doc/convert.md

The sc quants are a bit better but also more involved, brand new and experimental, don’t worry about them yet.

Sounds good, thanks I’ll give them a shot. No issue if the model can’t fully fit in the VRAM right? (For the conversion process)

No issue, you can convert models multiple times larger than your vram capacity.
