Launch: Verified Model Metrics
SUMMARY
Model evaluation scores are not always comparable across providers because teams use different test sets, confidence thresholds, and calculation methods, which makes selecting models for production unreliable. Roboflow Verified Model Metrics addresses this by calculating mAP using open-source COCO Evaluation methodology from the Supervision library on independent test

What is the Open Images Dataset? A Deep Dive.
SUMMARY
Open Images V7, released by Google in 2022, contains over nine million annotated images spanning nearly 20,000 categories and supports six annotation types: image-level labels, bounding boxes, segmentation masks, visual relationships, localized narratives, and point-level labels. That breadth makes it one of the few public datasets
