Base + Refiner Draft-to-Finish
text -> image·SDXL base -> SDXL refiner -> 4x ESRGAN upscaler (or FLUX.1 schnell draft -> FLUX.1 dev refine).·Shared seed across passes; denoise strength on the refine step; base/refiner step-split ratio; optional control net on the draft.·One model rarely optimizes both global composition and fine detail at once; splitting draft from refine lets a cheap fast pass explore many options and an expensive pass finish only the keepers.·Over-denoising the refine step drifts away from the draft composition; a mismatched seed breaks continuity between passes.
Summary
A fast base model lays down composition and structure, then a high-fidelity refiner pass adds detail and fixes artifacts, optionally followed by an upscaler.
- Stages
- Draft: text-to-image (SDXL base, FLUX.1 schnell)
- Refine: image-to-image (SDXL refiner, FLUX.1 dev)
- Upscale: upscale (Real-ESRGAN 4x)
- Use cases
- Hero art and key visuals
- Batch concepting then finishing keepers
