About
Segment Anything is a family of foundation models developed by Meta AI (FAIR) for promptable visual segmentation. SAM (2023) introduced zero-shot object segmentation in images from prompts; SAM 2 (2024) generalized this to video, adding real-time object tracking via a streaming memory. The models are released under open licenses (SAM 2 - Apache 2.0) together with datasets (SA-1B, SA-V).
