ZIMAGE EDIT + UPSCALE + MERGE WORKFLOW — v2.0

Use this workflow to edit generated images with text prompts or merge two same-seed image branches, with a cleanup pass and optional upscale; inputs include a generated image and edit prompts, or a shared seed and staged prompts for merging, and outputs can include edited or the

For edits, enter one change at a time or stack multiple prompts; prompt editing does not include inpainting, ControlNet, or masking.

For a merge, both branches use the same seed: Stage 1 creates the foundation, Stage 2 stops at end_at_step, and Stage 3 resumes at start_at_step and runs to end_at_step = TOTAL.

LatentBlend and ModelSampling let you tune the mix of style and composition; the Renderer Pass cleans an edited image before optional SeedVR2 upscaling.

The merge route produces a foundational image, an additional image, and then a merged image; an edited image can pass through the Renderer Pass before optional SeedVR2 upscaling.

Version v2.0 is based on ZImageTurbo.
