Meta releases Segment Anything Model as open source

Meta released the promptable Segment Anything Model, along with its code, model, web demo, and the SA-1B dataset.

Event details

Meta released Segment Anything Model, or SAM, on April 5, 2023. The model used an image encoder, prompt encoder, and lightweight mask decoder to generate segmentation masks from points, boxes, masks, or text prompts. Meta also released the model, code, and web demo, together with the SA-1B dataset of more than 1.1 billion masks on approximately 11 million images.

Why it matters

SAM extended the promptable foundation-model approach to pixel-level image segmentation and created a broad visual application ecosystem through an open model and large dataset.

99/100Global significance score. Regional effects are recorded only when the evidence supports a meaningful difference.

Access notes

The model, code, and web demo were public under the Apache 2.0 license.
