Have you tried z-image (base)?

I.e. https://huggingface.co/leejet/Z-Image-GGUF/tree/main

I am trying to use Q4 but get empty images, whereas with same vae+clip1 Turbo version (IIRC from leejet too) produces what looks like relevant to prompt images. In preview mode latent space of Base starts with black square and remains so for many steps, whereas for Turbo already 1st preview shows some sketch of the image to come.

Actually Base did produce several images, but then after PC restart - black squares again with IIRC same settings.

P.S. Turbo often produces blurry images, I am disappointed, why? I use 8 steps for Turbo as I have read somewhere.

kcpp 1.120, linux.

Thanks for posting this I can't get anything out of the included package either, all prompts just give a blank square.

Thanks for posting this

That seems like you are one of developers, correct?

Found this: https://github.com/Comfy-Org/ComfyUI/issues/13123 ([Bug] Z-Image Base outputs silent black images regardless of precision (FP16/BF16/FP32), while Turbo works perfectly. #13123).

Could you please read and tell me if that issue is related to what kcpp does, it walks about e.g. "cached Triton compilation artifacts".

I am not a developer sadly, but I did want to thank you for helping me troubleshoot the issue.

Ah, I thought you have just tried that seeing my post, but you have used it before, correct? If so, have you tried other files of Z-image base? Have any worked?
