Well it's bad compared to the original model, but is it bad compared to what else you could run in 64 GB?
I’m wondering myself: Do bigger models suffer less from quantization? Are there papers?
you can get a lot done with models well under that - the google and qwen 20-30B class models are fantastic
probably; 32-64 is the range where local models get extraordinarily useful, and in my experience any sub-4 quants get ridiculously incoherent, which is why those models tend to try to 'wow' people with tok/s rather than benchmarks.
haven't tried it yet though.
