# ASASR — Coloring the Noise: Adversarial Sobolev Alignment for Faithful Image Super-Resolution
Pretrained weights for the ICML 2026 paper
**[Coloring the Noise: Adversarial Sobolev Alignment for Faithful Image Super-Resolution](https://arxiv.org/abs/2605.23264)**
(Hongbo Wang, Huaibo Huang, Pin Wang, Jinhua Hao, Chao Zhou, Ran He).
➡️ **Code & full instructions: https://github.com/wafer-bob/ASASR**
ASASR performs ×4 image super-resolution with a **FLUX.1-dev** backbone and dual-LoRA
inference: a base **SR LoRA** (upscaling prior, OminiControl) plus our **DPO LoRA** trained
with a Sobolev frequency-weighted, adversarially-guided DPO objective (AS-DPO).
## Files
| File | Size | Use |
|---|---|---|
| `sr_lora/pytorch_lora_weights_v2.safetensors` | ~885 MB | base SR LoRA — **inference** |
| `dpo_lora/adapter_model.safetensors` | ~111 MB | ASASR AS-DPO LoRA — **inference** |
| `adv_lora/adapter_model.safetensors` | ~111 MB | rank-16 AMG adversary — **training only** |
## Download
```bash
huggingface-cli download wafer-bob/ASASR --local-dir ./checkpoints
```
Then follow the [GitHub README](https://github.com/wafer-bob/ASASR) for inference
(`bash scripts/infer.sh`) and training.
