A 2-stage upscaling workflow using FLUX.2 Klein in ComfyUI combines the model's image-editing capabilities with a secondary upscaler (such as SeedVR2) to produce high-resolution outputs — for example, first using FLUX.2 Klein to refine and upscale a base image to 2048px while injecting realistic detail, then using a tiled upscaler in Stage 2 to push the result to 4096px or beyond. A key consideration is using a reduced denoise strength (rather than 1.0) during the FLUX.2 Klein stage to preserve the original image's composition and avoid unintended changes such as altered facial expressions or gaze direction. The workflow leverages FLUX.2 Klein's efficient parameter count (available in 4B and 9B variants) and consumer-friendly VRAM requirements to make high-fidelity, multi-stage upscaling accessible on hardware such as an RTX 3090 or RTX 4070.
