10sorlabs Krea2 Image Workflow

A high-performance, full-featured full-stack generation and enhancement pipeline built specifically for Krea 2. This workflow integrates advanced latent upscaling, precise face detailing, and comparative analysis tools to deliver crisp, photorealistic results directly out of ComfyUI.

Key Features:

• Krea 2 Architecture: Utilizes the krea2_turbo_fp8_scaled.safetensors UNET combined with qwen3vl_4b_fp8_scaled.safetensors and custom LoRAs (famegrid_spicy, krea2-bloomgirls-realism) for enhanced character consistency and detail styling.

• High-Resolution Generation: Initializes at a crisp native latent canvas ($1448 \times 2176$).

• Two-Stage Upscaling Pipeline: Incorporates an integrated upscale stage utilizing 4xNMKDSuperscale combined with model-based scaling to maximize texture clarity without artifacting.

• FaceDetailer Integration: Built-in Ultralytics bounding box detection (face_yolov8m.pt) and SAM segmentation (sam_vit_b_01ec64.pth) for automated, seamless facial refinement and detail cleanup.

• Interactive Comparison Tools: Includes dual rgthree Image Comparers to visually inspect differences between upscale steps and contrast the base generation against the final enhanced output.

Requirements / Custom Nodes:

• ComfyUI-Impact-Pack

• ComfyUI-KJNodes

• rgthree-comfy (Power Lora Loader & Image Comparer)
