SAM3
SAM3 finds and segments every instance of a concept you describe with a short phrase, a box or a few clicks. In BOAT it powers text-to-mask, text-to-box, box and point prompts, auto search for tight masks and rotated boxes, and whole-image auto labeling.
Install
boat model install sam3Installs sam3:vit-h with 3.5 GB of weights into an isolated runtime.
You will be asked to accept the model's license on first install. Add --accept-license to accept it non-interactively. Read the terms
Tools
What SAM3 adds to the annotation editor. Each example loops what you do and what comes back.
