UnstableBastard

🔄 Updates

06.06.26 - managed to get it to generate on site but it does not work , don't waste buzz with model , just use the LoRAs

14.05.23 : Remade the 7th model , if you get black images with F16 model use the repaired BF16 model .

02.05.26 : Remade the model, should work now

01.05.26 https://pastebin.com/sKxCUSb6 script i used , replace base model , variants , weights , density and lambda with what you want . takes ~10 minutes on 32GB ram . If you encounter problems with the model please leave a comment or an image with prompt.

22.04.26 : Model (5.5) still not showing in model page or my profile :)) after almost 24H , I sure picked the best time to upload lol . Works with lora , tested some character lora as well , i have no idea why some work and others are not working ... almost deleted this model with all other model tests.

Works best with euler simple , CFG 1 and 9 steps . Try CFG 1.1 or max 1.5 with 9 to 11 max steps . Use a clip set last layer node and set it at -5 ;) .

15.04.26 : Made an inbreed model , it manages better in my opinion . Still not NSFW enough :( no breasts, nipples or puss control . LoRAs not tested with it . leave a comment or a image even with errors to see what i can do about it .

30.03.2026 : For fast conversion use this nice TOOL , made a Q8_0.gguf in " info: Completed in 29.14 seconds " .... yeah

25.03.2026 : Managed to modify the convert.py script from city96 to make the model directly in Q8_GGUF . Gemini for the win .

23.03.26 - Modified this nodes so it can accept negative weights and remade 3.5 with original ZIT for better layer stability ...i think . Merged with 2 random models from tensor hub for aesthetics , poses , clothes . I have no idea what it does better than v3.5 but i think it's different .

Usage : same as before - euler with simple , CFG 1 with 9 steps (best working and less horror, original text encoder (it does everything you want as long the model knows it).

Same as before i can't convert to GGUF , if someone knows and manages to do it he can post the GGUF model as his own (with a little mention of me :D ) ...

(Sample images are 1152x1536 , euler simple, 9 steps , no aura flow , no clip-skip , no LoRA , first run...the first run is bad for me after comfyui 0.17 update so the 2nd run without changing the prompt is better)

05.03.26 - File weights are broken because of lora / model merger node and can't convert to GGUF // stuck with this ...

04.03.26 - V3.5

• Sample images are 1024X1536 , 15 steps , CFG 1.5 ( on a RTX3060 12GB i get ~5-6s/it , Prompt executed in ~100 seconds - depends on how long the prompt is)

• About this version

  >>>Remake of V3 with new custom nodes from capitan01R (leave a star for him and try the new lora loader it's awesome) + some more LoRAs<<<

• Just like V3 most samplers/schedulers work and it has many changes from one to another , test them , mix them , some have body merging some don't , some work for fantasy some work for "erotic" stuff . Try them , try them with CFG >1 , try them with 10+ steps etc. Will update when i get more interesting LoRAs .

• Sampler : Euler_A / Euler

• Scheduler : sgm_uniform / simple

• Steps : 8 - 15

• CFG 1 - 1.5

• No Aura Flow Shift (better text render and no skin correction or whatever that shift does ) ,

• First generation with these settings is sometimes bad without a good prompt but the 2nd or 3rd without changing the prompt is good .

• It should work with ZIB and some ZIT LoRAs at low strength (did not test) .

Best settings for me V3:

• Sampler : er_sde / Euler

• Scheduler : Simple

• Steps : 8-9

• CFG 1 (sometimes 1.5)

• No Aura Flow Shift (better text render and no skin correction or whatever that shift does ) ,

• Added a CLIP set last layer node and i like to use -3 . Every change in clip skip is wild try from -1 to -10 (I'm too lazy to go past that) .

• First generation with these settings is sometimes bad without a good prompt but the 2nd or 3rd without changing the prompt is good .

26.02.2026 - changed file

Z-Bastard V3

• V3 = V2 (identical model).

• One version was removed because merging and re-merging produced the same result.

Recommended settings (ComfyUI):

• Sampler: Euler , Euler_A , DDIM , res_multistep etc .

• Scheduler: Simple , DDIM_uniform , SGM_Uniform , Beta etc.

• Try Aura Flow Shift: 2.5–3 max

• Also try without Aura Flow Shift — it behaves like a different model and the text is better.

• I use different sampler and scheduler almost every time, just load the image you like in comfyUI to see and compare with others .

• Higher Flow shift tends to make the skin more SDXL like .

🧠 How to Use Z-Bastard V1

• Use it like any Z-Image Turbo style model.

• ZIB-based LoRAs work well.

🧠 How to Use UnstableBastard Illustrious V1 and V2

General Generation

• Sampler: euler_A

• CFG: 3–5

• Steps: ~35

• Test different samplers — results can vary nicely.

🔍 High-Res Fix script (ComfyUI)

Using Efficiency Nodes Highres-Fix Script:

• Upscale: 1.25

• Steps: 12

• Iterations: 1–2 (2 is my favorite , refined from 768x1152 to 1200x1896 in ~120s with my 3060 12GB)

• Denoise: 0.26-0.36

👤 Face Detailer (ComfyUI – Impact Pack)

Recommended settings:

• Steps: 8

• Denoise: 0.26-0.36

• Lower chance of male faces becoming feminine

• Works with upside-down faces

• UltralyticsDetector Face model

If using ComfyUI, just load one of my images (workflow is embedded) and run it.

🎨 Realistic Images

For realistic outputs from ill with v1 and v2 i use :

• CyberRealistic / CyberIllustrious

• Highres-Fix Script enabled with one of the checkpoints above

You can use any checkpoint with this setup.

⚠️ Weaknesses

• Not great with complex backgrounds

• Struggles with fine detail-heavy scenes

🔗 LoRA Strength Guide

• 1–2 LoRAs → 0.5–1.0 strength

• Multiple LoRAs → 0.2–0.5 strength

(Adjust as needed.)
