ALWAYS LOOK INTO MY SAMPLES BEFORE DOWNLOADING TO UNDERSTAND IF THAT VERSION MEET YOUR EXPECTATIONS. Recommended generation parameters can be easily extracted in ComfyUI by dropping the sample into its window.
This is the CinEro NG Krea 2 series of checkpoints. Aimed to deliver the dark cinematic SFW / NSFW picture with unrestricted Qwen 3 VL Heretic Text Encoder. Trained with sci-fi horror themed moody portraits dataset. Developed mostly to be used in ComfyUI, but should work in other Stable Diffusion generation software.
Versions info
v2g Turbo
Recommended settings for Text-to-Image:
steps 7..9;
sampler "exp_heun_2_x0_sde" + "simple";
CFG 1.0..1.1;
initial resolution 0.75..1.6 MPx.
v2b Turbo
Recommended settings for Text-to-Image:
steps 7..12;
sampler "exp_heun_2_x0_sde" + "simple";
CFG 1.0..1.3;
initial resolution 0.75..1.2 MPx.
Euler and ER_SDE samplers give grid pattern. If you use ComfyUI I recommend adding the "ModelSamplingAuraFlow" node with "shift" parameter in 0.8..1.7. It probably also helps managing grid pattern.
v2a
BF16 is contrast and sharp, has more details in background. FP8 made by quantizing all tensors into FP8. My quick tests showed that FP8 sometimes give a textures with barely noticeable regular grid pattern (repeating grain noise on skin or sky, for example). It is needed to focus on textures to see, but sometimes noticeable. Let me know if you see such artifacts or other issues.
Recommended parameters and workflow can be extracted from my samples.
👇 READ THIS PLEASE 👇
I prefer 2-stage rendering. Text-to-Image at 0.75..1.2 MPx resolution (the lower resolution, the less stuff in scene) with any compatible sampler (Euler, sa_solver), er_sde, dpmpp_2m, seeds_2, seeds_3, gradient_estimation, exp_heun_2_x0_sde). Second pass (HiRes Fix) I'm doing with Details Daemon node. Krea 2 Turbo have a very tight CFG range (0.9..1.5). You cannot adjust contrast and details using CFG knob, because you need to be much more precise. Details Daemon let you smoothly regulate CFG scale depending on Time Step.
v1g INT8 COBVROT
Turbo workflow (10 steps) ==>> https://civarchive.com/images/141569765
Made from v1e (All in One) by applying more fine-tuning and quantization script to convert it into INT8 CONVROT.
For me it looks less contrast (better use 20 steps and CFG 3..5 or more). Also, it looks less stable. But twice smaller file.
Let me know please if that format works for you or you have any problem.
performance: someone might expect the speed increase, but unfortunately speed on 4060 TI and 5060 TI looks the same; below is the DEBUG output that lists the exact grouping of all tensors that depends on data bits of weight encoding.
[SaveAsSafeTensor] DEBUG: Tensors: 879, Dtypes: {'torch.bfloat16': 166, 'torch.float16': 40, 'torch.int8': 224, 'torch.float32': 225, 'torch.uint8': 224}
Roughly the half of the weights (insensitive ones) were encoded in INT8. Other tensors must be slower as they were encoded in FP32 or BF16.
troubles:
At least one user have problems with this version in ForgeNeo (don't know which version of it was used); looks like ForgeNeo do not properly recognize which loader needs to be used for Krea2 Turbo INT8 Convrot.
v1e All in One
It also has Qwen3VL Heretic Text Encoder and VAE baked in. Just use my workflow or use a regular Load Checkpoint node in ComfyUI combined with a regular KSampler. Nothing tricky needed. If you adapt the SDXL HiRes Fix technique described below, you may get better textures, but with v1e even single Text-to-Image pass at 1MPx resolution works well for me. Hope you will get good results also in your setup.
Recommended settings for Text-to-Image pass:
1216x832 (or 832x1216), Exp_heun_2_x0_SDE sampler (Simple, Normal, Beta, KL_Optimal schedulers), Steps 12, CFG 1.0...1.2.
v1
It has Qwen3VL Heretic Text Encoder baked in. So, by using this model you take full responsibility on the resulting safety of the rendered images. Qwen Image VAE also embedded. CLIP and Unet parts both quantized to FP8.

Привет! Нравятся твои модели. Можешь также выложить bf16 версию?
Могу, но она большая и без CLIP. Качество скорее всего эквивалентно.

о, свои, здравствуйте, братушки )
лайк. качаю.
а в int8 convrot можно пожалуйста?
[Вовка в 3/9 JPG]
Это я пока не умею. Надо книжечку почитать...
@homoludens comfyui-INT8-Fast
@nkinfe7788002789778 still cannot. I can run ComfyUI in fp8_e4m3fn mode, but the quality of the outcome is noticeably lower. Don't know if there is a support of int8 convrot mode in Comfy.
@evengar_ss @nkinfe7788002789778 Seems like I've found the way to convert
https://huggingface.co/obsxrver/ComfyUI-Native-INT8_ConvRot
Probably will find some time to adopt it.
@homoludens much appreciated, I would love to try your model but 24 GB is insanely big to dl and store on your hard drive. FP8 or int8 is good.
@ferrrett33 FP8 can be made soon. int8 convrot need more time
@evengar_ss то ли лыжи не едут, то ли INT8 Коньврот - какаха
love it :)
pretty awesome with Flux.2 as refiner.
kinda soft on it's own, but who cares. its very different from every other krea2 model i tried, and i tried a lot.
Yep.. I saw the images in your showcase with the similar or the same prompt. Your previous images done with deeply TURBO'ed model with a very high contrast and significantly more stuff and details. That is expected - this version is a low noise draft. XL or Flux refiner for high res fix is required for finishing. v1.0 BF16 UnetOnly version is a pure training on Krea2 RAW - no Turbo LORA integrated. You can add this lora to your workflow to shift closer to what results you had with other model. I plan to give more training and probably will make the next version more contrast.
@Wurstibert Could you please try the v1e. I made it more contrast and sharp. Might be significantly better.
@homoludens ok, i check it our :) the "old" one is still my daily go to favorite...
going to take a while tho, my internet is very slow
@homoludens ah its the all in one version tharts new? i cant run that on my 12gb vram, can i?
@Wurstibert I believe you can.
You need to run ComfyUI in fp8 mode, offload CLIP to CPU.
Samples inv1.0-UnetOnly and v1.0-unet-clip must contain the workflow with CLIP on CPU.
Spectacular model, thank you! Excellent work
