Flux.2-Klein Tiling Upscale Workflow

A ComfyUI workflow that uses Flux 2 Klein for the first upscale pass where detail is introduced carefully, then uses SeedVR2 to push the final resolution higher via tiling. The workflow maintains the general consistency of an initial image while upscaling and adding extra detail using Flux 2 Klein models. It employs a "divide and conquer" tiling strategy with automated image captioning to guide the diffusion model before upscaling, ensuring the upscale respects the image context.
