Can you post full context perplexity evaluations for respective quant sizes?

As in the title, I'd like to see any Llama 70B ppl tested on 4096 tokens for every quant size. 70B-chat would be okay. Can't do it on my end because of VRAM.

I did some 4096 token tests on base Llama2-70B using wikitext-train:

bpw	ppl
2.5	6.6602
2.7	4.8695
3.0	4.1078
3.5	3.5893
4.0	3.4730
4.65	3.4169

I don't have a 5.0bpw model handy to test, and I don't have the VRAM to test higher than that. I'd have to fire up a RunPod instance and that would take hours to set up.

Thanks.
