## AI overview

The article demonstrates how GPT-6 Astra can produce polygon outlines for described objects, then compares those outputs with SAM 3 masks. It recommends pairing Astra's boxes with SAM 3 for more accurate segmentation, particularly when pixel-accurate masks are needed.

## Source excerpt

GPT-6 Astra can return polygon outlines for any object you describe. They are not pixel masks, so we benchmarked them against SAM 3 and show how to combine the two.
