SAM 1: selecting an object with a point or a box
The original 2023 Segment Anything release, now commonly called SAM 1, turns a click, box, or rough mask into an object segmentation, giving annotators and analysts an editable first pass across varied images.

- How we know ↓
Drawing precise boundaries around objects is slow, repetitive work in image annotation and analysis.
Segmentation systems usually needed category-specific labels and training before they could help on a new collection.
A promptable vision model produces candidate masks for objects without training a new model for each object category.
What was shown, and what wasn’t
Shown
Meta released SAM 1 inference code, Apache-2.0 model checkpoints, notebooks, and separate access to the SA-1B dataset in April 2023.
Not shown · limits
- A plausible mask may still be wrong, especially in unfamiliar imagery. Apache-2.0 model artifacts do not settle the rights attached to input images, dataset access, or downstream uses.
- This is the historical SAM 1 release, not a claim about later Segment Anything generations. The official repository establishes Apache-2.0 model artifacts and intended workflows; SA-1B data access and downstream image rights remain separate.
Bright editorial interpretation
Promptable masks can move human effort from drawing every boundary to checking and correcting proposals.
