Highlighted rows are where these differ.
YOLO-World
- The speed of YOLO with text-defined classes
- Weaker than Grounding DINO on hard prompts
Best for prompted detection that has to be fast.
RF-DETR
- Leads the RF100-VL domain-transfer benchmark
- DINOv2 backbone, markedly better on occluded objects
- Apache 2.0, which YOLO is not
Best for most custom detection tasks.
RTMDet
- Wins on raw speed where accuracy is sufficient
- MIT, so no derivative-work obligation
Best for high frame-rate video.
