LibreRTDETRv4x

RT-DETRv4-X HGNetv2 COCO detector, repackaged for the LibreYOLO framework.

Source

Derived from https://github.com/RT-DETRs/RT-DETRv4 at commit 43663fb103fc86a5da28806d8aeecdc707c4d6e0 and upstream checkpoint: https://drive.google.com/file/d/19gnkMTgFveJsrOvSmEPQXCTG6v9oQHN3.

RT-DETRv4 is Apache-2.0 licensed. The upstream training recipe uses a DINOv3 teacher model; DINOv3 materials are not included in this repository.

Modifications

EMA weights were unwrapped, the training-only encoder.feature_projector.* tensors were omitted, and the checkpoint was saved with LibreYOLO metadata schema v1.0. The inference graph uses the exported student detector weights.

Validation

This file was validated locally with LibreYOLO checkpoint metadata schema v1.0, loaded through LibreYOLO, and evaluated on coco128.yaml with workers=0, batch=8, conf=0.001, iou=0.6.
