## Contents

| Path | Size | What it is |
|---|---|---|
| `ema/` | 8.6 GB | EMA weights for the backbone |
| `boxnet/` | 7.4 GB | Joint image + bounding-box diffusion backbone |
| `pytorch_lora_weights.safetensors` | 1.2 GB | LoRA adapter weights |

**Inference weights only.** Optimizer, LR scheduler, RNG and dataloader state were not
uploaded, so this checkpoint cannot be used to resume training.
