## Inference Checkpoints

| Variant | Dataset | Faces | Decoder | Diffusion | State |
| --- | --- | ---: | --- | --- | --- |
| `4-30` | DeepCAD | 4–30 | `deepcad/hifi-brep-decoder-4-30.pt` | `deepcad/hifi-brep-diffusion-4-30.pt` | online |
| `7-30` | DeepCAD | 7–30 | `deepcad/hifi-brep-decoder-7-30.pt` | `deepcad/hifi-brep-diffusion-7-30.pt` | online |
| `abc-4-50` | ABC | 4–50 | `abc/hifi-brep-decoder-4-50.pt` | `abc/hifi-brep-diffusion-4-50.pt` | EMA |

HuggingFace:

```bash
hf download 1nnoh/HiFi-BRep \
  --include "deepcad/*.pt" "abc/*.pt" \
  --local-dir checkpoints
```

ModelScope:

```bash
python -m pip install modelscope-hub==0.1.8
modelscope download innohou/HiFi-BRep \
  --include "deepcad/*.pt" "abc/*.pt" \
  --local-dir checkpoints
```
