Open-sourcing RightWayUp - a 360-degree image rotation model, and a JPEG shortcut we found in a common benchmark [P]

RightWayUp, a new 360-degree image rotation detection model, has been open-sourced. In tests with held-out images, RightWayUp Max achieved 93.0% accuracy within 10°, outperforming Woehrer 2026's 88.4%. On Woehrer 2026's COCO-based benchmark, RightWayUp demonstrated 98.8% accuracy within 10° (five-seed mean) compared to Woehrer's 98.0%. Additionally, RightWayUp correctly oriented every image on RotBench.

This model not only outperforms Woehrer 2026 on its own benchmark (98.8% vs 98.0%) but also achieves 93.0% accuracy on held-out images, unlike other models.
