## Performance Tips

| Resolution | Steps | Est. Time |
|-----------|-------|-----------|
| 256×256   | 8     | 1-3 min   |
| 384×384   | 8-10  | 2-5 min   |
| 512×512   | 8-12  | 4-10 min  |
| 768×768   | 8-12  | 10-25 min |

First generation triggers PyTorch JIT compilation and is slower. Subsequent runs are faster.
