# LibreDFINEx
D-FINE-x (xlarge) detection weights, repackaged for LibreYOLO.
Reported COCO val2017 mAP50-95: **59.3**.
## Source
Derived from [Peterande/D-FINE](https://github.com/Peterande/D-FINE) at the v1.0
release ([`dfine_x_obj2coco.pth`](https://github.com/Peterande/storage/releases/download/dfinev1.0/dfine_x_obj2coco.pth)).
This checkpoint is pretrained on Objects365 and then fine-tuned on COCO. Typically +3.5 mAP over the COCO-only checkpoint.

## Modifications
Checkpoint metadata wrapping only — learned parameters are unchanged.
The wrapper adds ``model_family``, ``size``, ``nc``, and ``names`` fields so the
unified ``LibreYOLO()`` factory routes correctly without filename heuristics.
See `weights/convert_dfine_weights.py` in the
[LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo).
