Meta Segment Anything Model 2 (SAM 2) is a next-generation model developed by Meta for real-time, promptable object segmentation in videos and images. It achieves state-of-the-art performance and supports zero-shot generalization, allowing it to be applied to previously unseen visual content without needing custom adaptation. The release of SAM 2 follows an open science approach, with code and model weights shared under the Apache 2.0 license, and the SA-V dataset shared under the CC BY 4.0 license.
