| A **1-step ResShift** super-resolution student as a pixel-space **`IMAGE → IMAGE`** |
| upscaler for ComfyUI, at **×4 or ×2** (a `scale` dropdown on the loader). The student is |
| distilled (paper [2603.22490](https://arxiv.org/abs/2503.13358), [repo](https://github.com/Daniil-Selikhanovych/RSD), *One-Step Residual |
| Shifting Diffusion via Distillation*) from a 15-step ResShift teacher, so it does the |
| whole super-resolution jump in a **single stochastic network step** — no multi-step |
| sampler, no CFG. |
|
|
| It is **model-agnostic**: drop it after `VAEDecode` / before `SaveImage` and it upscales |
| any RGB image, not just Anima / diffusion output. |
