Small, fast, no magic nodes. Just what you need to run Krea2 clean.<hr />What it does<ul><li>Text-to-image with Krea2</li><li>Optional upscale pass — toggle on/off</li><li>Built-in image comparer (base vs upscaled)</li><li>Power LoRA slot ready to plug your stacks</li></ul>Everything runs off the same Krea2 model — no extra checkpoints, no heavy upscalers loading in and out. On my machine (RTX 5070 Ti, 16GB VRAM, 48GB RAM): ~29s base, ~60s with upscale.<hr />Design choice — the upscaleI could have plugged SeedVR or a heavy upscaler here. Better quality, sure — but you'd be loading a second model into VRAM and paying the price on every generation.Instead, the upscale runs Krea2 itself over an ImageScaleBy 1.5x → low-denoise refine. Same model already in memory, no context switch. It's a deliberate compromise: not the sharpest possible option out there, but the quality-to-speed ratio sits exactly where I wanted it — usable on a home PC, no minutes-per-image waits.Heads up — I'm likely dropping a follow-up version in the next few days with SeedVR integrated as a second upscale option, not a replacement. You'll be able to pick which method fits the shot.<hr />Requirements<ul><li>Krea2 — I run <code>krea2TurboFP8</code> (~12GB, fp8 safetensors)</li><li>Text encoder — Qwen3-VL 4B (~5GB in the variant I use)</li><li>VAE — <code>qwen_image_vae</code> (~250MB)</li></ul>Tighter VRAM: the ComfyOrg repo also ships an nvfp4 build (~7GB). The workflow is built for <code>.safetensors</code>, not GGUF — keep that in mind if you're shopping for lighter variants.Custom nodes:<ul><li><code>rgthree-comfy</code> — Power LoRA Loader, Fast Groups Muter, Image Comparer</li><li><code>easy-use</code> — set/get nodes</li><li><code>ComfyUI-ConditioningKrea2Rebalance</code> (nova452) — per-layer conditioning tuning, dialed in for Krea2</li><li><code>comfyui_image_metadata_extension</code> (Santodan)</li></ul><hr />Krea2 clicked for me the second I loaded it. First base model in a while where realism doesn't need me to fight the sampler.— ShinobiSat

Krea2 Workflow — ShinobiSat Workflows

<ul><li>Added SeedVR2 as a second upscale path — sits next to the original Krea2 native upscale, not replacing it</li><li>Both methods are toggle-able via Fast Groups Muter — pick per generation, or leave both off for base only</li><li>Added a subtle film grain pass on the output (off by default, easy to enable)</li><li>Everything else — txt2img, Power LoRA slot, Image Comparer, base structure — unchanged from V1.0</li></ul>
