A few people here tried the Goliath-120B model I released a while back, and looks like TheBloke has released the quantized versions now. So far, the reception has been largely positive.

The fact that the model turned out good is completely unexpected. Every LM researcher I’ve spoken to about this in the past few days has been completely baffled. The plan moving forward, in my opinion, is to finetune this model (preferably a full finetune) so that the stitched layers get to know each other better. Hopefully I can find the compute to do that soon :D
On a related note, I’ve been working on LLM-Shearing lately, which would essentially enable us to shear down a transformer down to much smaller sizes, while preserving accuracy. The reason goliath-120b came to be was an experiment in moving at the opposite direction of shearing. I’m now wondering if we can shear a finetuned Goliath-120B to around ~70B again and end up with a much better 70B model than the existing ones. This would of course be prohibitively expensive, as we’d need to do continued pre-train after the shearing/pruning process. A more likely approach, I believe, is shearing Mistral-7B to ~1.3B and perform continued pretrain on about 100B tokens.
If anyone has suggestions, please let me know. Cheers!
My test was logs of chats with characters. Something that isn’t widely publicly available so it can’t be gamed. Xwin has very bad perplexity on those. Below that of codellama-34b.
xwin: 4.876139163970947
Codellama: 4.689054489135742
Same quantization…
70b-base scores: 3.69110918045044 Euryale-1.3: 3.8607137203216553
Dolphin 2.2 did surprisingly bad: 4.39600133895874 but not as bad as xwin.
Obviously it doesn’t 100% track to a good model but all things combined about xwin (refusals, repeat issue, perplexity) put me off from it in a big way.
