FLUX Kontext — Character-Consistent Image Editing (ComfyUI Workflow)

A ComfyUI node graph (not model weights) for editing clothing, background, or style of an image while preserving character identity, using FLUX.1 Kontext Dev as full visual context (not mask-based inpainting).

When to use it

Best for broad semantic changes (full outfit, background, style). For precise, localized touch-ups, combine with traditional inpainting rather than replacing it.

Tested parameters

Denoise between 0.55 and 0.70 gives controlled changes without breaking character identity — outside that range the character degrades or the edit barely applies.

Requirements

—12GB VRAM recommended (16GB+ unrestricted).
—Viable on 8GB with a quantized GGUF Q4/Q5 build, offload enabled, resolutions ≤768px.
—Time: 40-120 seconds per image.
—Nodes: UNETLoader, DualCLIPLoader, VAELoader, Load Image, Kontext Image Encode, Flux Guidance, KSampler, VAEDecode, Save Image.
