Released on November 19th, 2025, [Segment Anything 3 (SAM 3)](https://blog.roboflow.com/what-is-sam3/) is a new, zero-shot instance segmentation developed by Meta. You can use SAM 3 to generate precise segmentation masks for objects in an image or video using either text or point prompts.

You can fine-tune SAM 3 with any instance segmentation dataset hosted on Roboflow. To fine-tune a SAM 3 model, create a new dataset version in your instance segmentation project, then select SAM 3 from the list of training options on your dataset version page.
