ALWAYS LOOK INTO MY SAMPLES BEFORE DOWNLOADING TO UNDERSTAND IF THAT VERSION MEET YOUR EXPECTATIONS. For the best quality results use the <a target="_blank" rel="ugc" href="https://civarchive.com/models/3048105/cinero-ng-krea2-2pass-workflow-for-comfyui-4-4-steps">recommended ComfyUI workflow</a>.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.<h3 id="v5">v5</h3>Better realism, cinematic lighting lighting, textures, prompt adherence, bla-bla-bla.Recommended setup: Text-to-Image + Hi Res Fix. You can use 4-8 steps for T2I and 4 steps (3 steps might also work with lower denoise) for next passes. I use 5 -&gt; 6 -&gt; 4 steps (T2I -&gt; I2I -&gt; I2I). Euler A and DPM++ 2S A samplers work for Text-to-Image. Beta scheduler is good for Text-to-Image and Zeta scheduler is good for texture improvement during Hi Res Fix.Special note: I suspect that amount of details can be increased if you start rendering image at 1.85 MPx resolution instead of regular 1MPx reso.<h3 id="v4">v4</h3>More tuning on realism, natural materials, lighting, body lang, cinematic / analog look, added creativity. I recommend using the DetailsDaemon technique for better control of contrast and textures. Look into my samples for reference workflow for ComfyUI.Recommended setup: Text-to-Image + Hi Res Fix or triple pass workflow. You can use 5 steps for T2I and down to 4 steps for next passes. I use 5 -&gt; 6 -&gt; 4 steps (T2I -&gt; I2I -&gt; I2I).<h3 id="v3e">v3e</h3>TL;DR; Main difference from v3-alpha is better ethnicity adherence and face diversity; reduced dithering and increased texture / hairs smoothness.Introduction of trigger words means better adherence to the ethnicity in prompt. v3-alpha has weaker distinction between those nationalities. Also, the secondary goal of the training was the improvement of textures and reduction of dithering / regular grid pattern issue. Picture must be little bit smoother in v3e.<h3 id="v3-alpha">v3-alpha</h3><ul><li>More training on sci-fi, horror, street photography, cinematic portraits (sfw/nsfw).</li><li>6-9 steps for Text-to-Image AND 4+ steps for Image-to-Image (Hi Res Fix).</li><li>Not a final quality.

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.<h3 id="v2a">v2a</h3>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.<h3 id="v1g-int8-cobvrot">v1g INT8 COBVROT</h3>Turbo workflow (10 steps) ==&gt;&gt; <a target="_blank" rel="ugc" href="https://civarchive.com/images/141569765">https://civarchive.com/images/141569765</a>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. <span style="background-color:rgb(26, 27, 30);color:rgb(193, 194, 197);font-family:-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Helvetica, Arial, sans-serif, Apple Color Emoji, Segoe UI Emoji;font-size:16px">[SaveAsSafeTensor] DEBUG: Tensors: 879, Dtypes: {'torch.bfloat16': 166, 'torch.float16': 40, 'torch.int8': 224, 'torch.float32': 225, 'torch.uint8': 224}<span style="background-color:rgb(26, 27, 30);color:rgb(193, 194, 197);font-family:-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Helvetica, Arial, sans-serif, Apple Color Emoji, Segoe UI Emoji;font-size:16px">Roughly the half of the weights (insensitive ones) were encoded in INT8.

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.<h3 id="v1">v1</h3>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.
