+# DDT: Decoupled Diffusion Transformer
+## Introduction
+We decouple diffusion transformer into encoder-decoder design, and surpresingly that a **more substantial encoder yields performance improvements as model size increases**.
+![](./figs/main.png)
+## Visualizations
+![](./figs/teaser.png)
+## Usgae
+```bash
+# for training
+python main.py fit -c configs/repa_improved_ddt_xlen22de6_256.yaml
+```
+
+```bash
+# for inference
+python main.py predict -c configs/repa_improved_ddt_xlen22de6_256.yaml --ckpt_path=XXX.ckpt
+```
