YOLO27 model family preview
Detection uses compact CNNs for N/S and query-based, NMS-free models for M/L; other tasks use CNNs. These preliminary benchmarks may change. Weights and package support are not available yet: the example is for use after release. N/S detection defaults to NMS; nms=False selects the NMS-free head used for timing, while N/S accuracy depends on the selected head.
# After YOLO27 is released

Frequently asked questions
YOLO27 is the upcoming Ultralytics model generation. The announced family includes four sizes and seven vision tasks. Explore the official YOLO27 overview for product details and the documentation for technical information.
The announced lineup has four sizes: YOLO27n and YOLO27s target edge devices, YOLO27m targets production GPU workloads, and YOLO27l targets applications that prioritize accuracy. The hybrid architecture adapts to each size, and Ultralytics reports YOLO27l exceeds 60 mAP on COCO. Compare the announced improvements, then validate models on your own data when released.
The YOLO27 overview announces object detection, instance segmentation, semantic segmentation, depth estimation, image classification, pose estimation, and oriented object detection. Four sizes across seven tasks make a planned family of 28 models with a shared interface.
Organize your images, review annotations, and establish a baseline with YOLO26 today. Use Ultralytics Platform to prepare datasets and training workflows, then evaluate YOLO27 on the same data when it launches.
