There are so many YOLOx out there on GitHub but not every YOLO author has published detailed mAR results with different experiment setups with respect to image resolution, throughput, GPU hardware, etc.
YOLOv4 and YOLOv7 are by the original YOLO authors, Chien-Yao Wang, Alexey Bochkovskiy and Hong-Yuan Mark Liao, with the arxiv papers in detail.
I used VDP to build a pipeline for each in minutes and came up with a Stremalit live demo page, so one can tell their qualitative results really quick.
