 ### Grounded-SAM-2 Image Demo (with Grounding DINO 1.5 & 1.6)
 
 We've already released our most capable open-set detection model [Grounding DINO 1.5 & 1.6](https://github.com/IDEA-Research/Grounding-DINO-1.5-API), which can be combined with SAM 2 for stronger open-set detection and segmentation capability. You can apply the API token first and run Grounded-SAM-2 with Grounding DINO 1.5 as follows:
