API README

Flux Differential Diffusion

Flux Differential Diffusion belongs at the graduated revision across a single image stage of a visual workflow. Rather than treating the model as an isolated demonstration, teams can place it inside briefing, review, selection, and handoff practices where creative teams can plan a continuum between untouched and substantially changed areas instead of reducing every decision to a binary selection. This positioning clarifies why the model earns a place in a real creative pipeline and what kind of decision it helps people make.

A practical use of Flux Differential Diffusion is portrait retouching, atmosphere shifts, material changes, and localized art direction that should taper naturally into preserved content. Begin by agreeing on the creative objective and review criteria, prepare only the source material needed for that objective, and compare results against audience, brand, editorial, and production needs. Technical request choices remain documented below so the prose can stay focused on planning and creative value.

Highlights

Spatially varying edit strength. Allows strong regeneration in selected areas while other regions change only subtly.

Smooth transition zones. Blends different denoising intensities without hard visual seams between regions.

Fine-grained creative control. Supports nuanced retouching, emphasis, and localized restyling beyond a binary mask.

Context-preserving synthesis. Uses surrounding image information to keep altered regions visually integrated. This configuration emphasizes the model family's characteristic balance of prompt accuracy, visual detail, and creative flexibility.

Prompt Guide

Lead with the main subject and action, then specify composition, context, lighting, materials, style, typography, and atmosphere. For editing, identify each source and clearly separate the requested transformation from the subjects, regions, geometry, or identity that must remain unchanged.
