Meta SAM 2 is an open-source image segmentation model developed by Meta AI as part of its ongoing Segment Anything initiative. It’s engineered to perform zero-shot segmentation—meaning it can segment unfamiliar objects without retraining. With just a single click or prompt, SAM 2 can produce pixel-accurate segmentation masks across a vast range of images.
Unlike traditional vision models that require large amounts of labeled data, SAM 2 generalizes across domains, making it ideal for real-world use cases like augmented reality, medical imaging, content editing, and autonomous robotics. It can be accessed via Meta’s demo site, integrated via API, or fine-tuned with your own datasets—making it flexible for both academic and commercial applications.
