• [2025.11.18] Release the newest member of the RT-DETR family: RT-DETRv4:Painlessly Furthering Real-Time Object Detection with Vision Foundation Models. By harnessing the rapidly evolving capabilities of Vision Foundation Models (VFMs), we boost lightweight detectors and, without incurring any extra inference latency, significantly improve the performance of the full-size model.
• [2024.11.28] Add torch tool for parameters and flops statistics. see run_profile.py
• [2024.10.10] Add sliced inference support for small object detecion. #468
• [2024.09.23] Add ✅Regnet and DLA34 for RTDETR.
• [2024.08.27] Add hubconf.py file to support torch hub.
• [2024.08.22] Improve the performance of ✅ RT-DETRv2-S to 48.1 mAP (+1.6 compared to RT-DETR-R18).
• [2024.07.24] Release ✅ RT-DETRv2!
• [2024.02.27] Our work has been accepted to CVPR 2024!
• [2024.01.23] Fix difference on data augmentation with paper in rtdetr_pytorch #84.
• [2023.11.07] Add pytorch ✅ rtdetr_r34vd for requests #107, #114.
• [2023.11.05] Upgrade the logic of remap_mscoco_category to facilitate training of custom datasets, see detils in Train custom data part. #81.
• [2023.10.23] Add discussion for deployments, supported onnxruntime, TensorRT, openVINO.
• [2023.10.12] Add tuning code for pytorch version, now you can tuning rtdetr based on pretrained weights.
• [2023.09.19] Upload ✅ pytorch weights convert from paddle version.

• [2023.07.30] Release RT-DETR-R50 pretrained models on objects365. 55.3 mAP and 108 FPS.
• [2023.07.28] Fix some bugs, and add some comments. 1, 2.
• [2023.07.13] Upload ✅ training logs on coco.
• [2023.05.17] Release RT-DETR-R18, RT-DETR-R34, RT-DETR-R50-m（example for scaled).
