Weights download automatically; Hugging Face access to the official checkpoint is required.
from sam3_mlx import build_sam3_image_model
from sam3_mlx.model.sam3_image_processor import Sam3Processor
model = build_sam3_image_model()
processor = Sam3Processor(model, resolution=1008)
state = processor.set_image("image.jpg")
state = processor.set_text_prompt("shoe", state)
masks, boxes, scores = state["masks"], state["boxes"], state["scores"]
Use a resolution divisible by 14. Selected-frame video runs each frame independently; temporal tracking and SAM 3.1 are experimental.
