## Checkpoints

| Step | Loss | Path |
|------|------|------|
| 10,000 | 0.0194 | `checkpoints/10000/pretrained_model/` |
| 8,000 | 0.0262 | `checkpoints/8000/pretrained_model/` |

## Usage

Load from a specific step:

```python
from pathlib import Path
# Use checkpoints/<step>/pretrained_model/ with the GR00T inference stack
ckpt = "pravsels/groot1.7_block_stack/checkpoints/10000/pretrained_model"
```
