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.
What happened
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.
Assessment
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.

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