Meta Segment Anything Model 2

SAM 2 introduces a single, Apache-2.0-licensed checkpoint capable of zero-shot object segmentation across stills and footage. Users can prompt with a click, box or rough mask; the model tracks selected items through occlusions, motion blur and scene cuts in real time. Optimised for CPU and GPU deployment, SAM 2 integrates into mobile apps, annotation pipelines and research workflows, reducing manual masking hours to seconds without additional fine-tuning.
