Z-Image is here, and it's pretty damn great. Let's make it more NSFW!
Still a work in progress. It can output good genitals, but not always. About 3/5 images are good, working on penis stability specifically for future versions.
ComfyUI: Models should be placed in diffusion_models, and uses the official workflow with the Load Diffusion Model loader, and loading the VAE/CLIP models separately. Models named "_AIO" should go in the checkpoints folder, and uses the normal checkpoint loaders.

4.5 is great, 5.0 has too much contrast. My favorite still 4.5, but maybe it change in future. Even if 5.0 is not to great thanks for the work!
Thanks for the feedback! It's good to know what people prefer.
6.0 is an evolution of 5.0 so you probably won't be too into it.
care to make an FP16 version for those who do not support bf16?
Sure, I can upload. I won't have time to create new preview images for them though.
@Meandmeitsperfect FP16 is up.
Is there a difference? The size is the same at least. I don't understand these formats well :)
@6tZ thank you so much!
@6tZ there is a big difference, my gpu don't support BF16 or FP8 so it have to emulate it, to emulate an fp8 the gpu uses a whole fp16 instruction that is double the size but because of the emulation have half the precision so: no gain in speed, but loss in quality. with the fp16 model I can obtain a way better quality :)
@Meandmeitsperfect I see, okay! What GPU is this? Good to know where the limits are. I also added an fp8 model.
The FP16 does seem to add some kind of weird noise to the output though.

Here's a comparison. FP16 in the middle.
@6tZ why are you usinf flux_VAe instead of AE_Vae or Zimage_Vae? I've used yout prompt and your parameters with other 3 FP16 model and there is no mid frequency noise
@6tZ both RTX 20x0 and RTX30x0 family doesn't support native FP8 or BF16
@Meandmeitsperfect Oh really? Hmm, I'm not sure what that means, but I feel like I was running all sorts of models with my 3090 before I upgraded to the 50-series...
@Meandmeitsperfect flux_VAE is just renamed ae.sft
