A universal, production-ready ComfyUI workflow for the Krea 2 ecosystem, supporting all model variants (Base, Turbo, FP8, BF16) with native ultra-HD generation and 3 interchangeable upscale & refinement modules.
✨ Key Features
- Universal Multi-Precision Support: Fully compatible with any Krea 2 checkpoint (Base, Turbo, FP8, BF16). Just adjust your sampling steps accordingly (e.g., 8 steps for Turbo, 20–30 steps for Base).
- Ultra-HD Native Base: Pre-calibrated with ResolutionSelector (native 2MP & 4MP at multiple = 32) for crisp, blur-free baseline details without early distortion.
- 3-Way Upscaling & Refine (Pick ONE via Fast Groups Muter):
1. Krea 2 Dual Upscale (Main): Native latent 1.5× redraw with ColorMatch for clean, pristine skin and fabric textures.
2. SeedVR2-int8 Upscale: Fast 1-step DiT tiled detail restoration powered by SeedVR2-7B-int8.
3. Flux2-Klein Refine: High-precision 1.5× redraw using Flux2-Klein-9B + ReferenceLatent injection.
- Clean Architecture: 100% native ComfyUI nodes, pixel-perfect alignment, and zero missing node errors.
💡 Quick Guide
- Keep [Hs Krea 2 Txt2Img] enabled.
- Select your preferred Krea 2 checkpoint in the UNET loader.
- In [Fast Groups Muter], enable only ONE upscale group (Dual Upscale, SeedVR2, or Flux2-Klein) to save VRAM and rendering time.
