RF-DETR Large: best OSS-licensed object detector at just 34M params

TheZachMueller · x · 2026-11-12

Object detection now needs surprisingly little VRAM. The current best OSS-licensed (Apache-2.0) detector is Roboflow's RF-DETR Large at only 34M params, live on Hugging Face and integrated into Transformers. Architecture: a DINOv2-with-registers style ViT backbone with RF-DETR windowed attention, a C2f-style multi-scale projector, a deformable DETR decoder with Group DETR-style parallel training for fast convergence, scaled via NAS across accuracy–latency tradeoffs.
