Jib Mix Zit is an upgrade for realistic images, sharper and prettier faces.<hr />Jib Miz Zit V2:<ul><li>Better fine small details (especially in backgrounds)</li><li>More variation in image and Style (Doesn't always produce photo realism but can be a nice surprise)</li><li>Less Zit mottled Skin.</li><li>More Varied faces and poses.</li><li>- A bit less photo-realistic.</li></ul><hr />I recommend the <a target="_blank" rel="ugc" href="https://civarchive.com/api/download/models/2511897?type=Model&amp;format=SafeTensor&amp;size=full&amp;fp=fp16">FP16 </a>model for 12GB of Vram and up But a smaller <a target="_blank" rel="ugc" href="https://civarchive.com/api/download/models/2511897?type=Model&amp;format=SafeTensor&amp;size=pruned&amp;fp=fp8">FP8 </a>model is available. For Best Image Quality try: I recommend using 80% of the UltraFlux VAE merged on the fly with 20% of the Normal Zit/Flux VAE for sharper images UltraFlux VAE: <a target="_blank" rel="ugc" href="https://huggingface.co/Owen777/UltraFlux-v1/tree/main/vae">https://huggingface.co/Owen777/UltraFlux-v1/tree/main/vae</a> This custom nod: <a target="_blank" rel="ugc" href="https://civarchive.com/models/2231351?modelVersionId=2638152">https://civarchive.com/models/2231351?modelVersionId=2638152</a> does a merge of the 2 VAE on the fly as the UltraFlux- VAE can be a little too sharp-looking on its own and definitely is if you use it for upscales. V1 model can benefit from a small amount more of my Zit lora (around 0.15): <a target="_blank" rel="ugc" href="https://civarchive.com/models/2194714/jib-mix-realistic-z-image-lora">https://civarchive.com/models/2194714/jib-mix-realistic-z-image-lora</a> I recommend ClownSharkSampler and Linear/ralston_2s for detail. <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/516449b9-ed17-4e04-aefd-b44fc1336284/width=525/516449b9-ed17-4e04-aefd-b44fc1336284.jpeg" />with some added noise option nodes. It has been tuned against my workflow (I have a version posted here: <a target="_blank" rel="ugc" href="https://civarchive.com/models/2194714?modelVersionId=2481800">https://civarchive.com/models/2194714?modelVersionId=2481800</a>)

Jib Mix ZIT

01/02/2026 v2I updated some of the Python code in vae_merge.py as there was an error if one VAE was loaded on the GPU and the other on the CPU, hopefully this is now fixed. Custom node needed to get the best image quality out of ZIT. Use it to mix Ultra Flux VAE and Normal Flux VAE at 40%-90% strength. It can be a bit buggy, but you disable it for 1 gen and then enable it again and it seems to work.
