# LibreDFINEm

D-FINE-m (medium) detection weights, repackaged for LibreYOLO.

Reported COCO val2017 mAP50-95: **55.1**.

## Source

Derived from [Peterande/D-FINE](https://github.com/Peterande/D-FINE) at the v1.0
release ([`dfine_m_obj2coco.pth`](https://github.com/Peterande/storage/releases/download/dfinev1.0/dfine_m_obj2coco.pth)).
This checkpoint is pretrained on Objects365 and then fine-tuned on COCO. Typically +2.8 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.

[LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo).
