This model seems to be very broken, I attempted to also quantize it and I am getting divulges into nonsense or repeating words endlessly no matter the settings. :/
All yi models are extremely picky when it comes to things like prompt format, end string, and rope parameters. You'll get gibberish from any of them unless you get everything set up just right, at which point they perform very well.
Thanks for confirming this. I've seen so much praise for these models, yet I've experienced no end of problems in trying to get decent, consistent output. A couple of Yi finetunes seem better than others, but there are still too many problems for me to prefer them over others (for RP/chat purposes.)
I'm still hopeful it's just a matter of time (and a fair amount of trial-and-error) before myself, app developers and model mixers, work out how to get fantastic, consistent out-of-the-box results.
Hm. I just load gguf yi-34b-chat q4_k_m in oobabooga via llama.cpp with default params and 8k context and it's just work like a charm. Better (more lively language) than any 70b from openrouter (my local machine can't handle 70b)
It's a new foundational model, so some teething pains are to be expected. Yi is heavily based on (directly copied, for the most part) llama2, but there are just enough differences in the training parameters that default llama2 settings don't get good results. KCPP has already addressed the rope scaling, and I'm sure it's only a matter of time before the other issues are hashed out.
