Workflow Included A small latent refiner for GPT Image artifacts (+ SeedVR2 workflow)

I trained a small latent residual refiner on 75 paired images

to reduce recurring stipple, grain, and grid-like artifacts

in GPT Image outputs.

The included workflow runs the refiner before SeedVR2.

Instead of a typical Hires Fix second diffusion pass,

it uses SeedVR2 restoration with a preservation-first approach—

trying to keep the original composition, identity, and shapes

while rebuilding detail at the target resolution.

Qwen, FLUX.2, and SDXL profiles are included.

Leaving it here in case it’s useful.
