The system interprets natural language instructions, converts them into segmentation prompts, runs SAM 3, verifies results with the VLM, and refines prompts in a feedback loop until the correct object is segmented. Full Python code is provided covering model loading, VLM inference, SAM 3 text-prompted segmentation, the agentic loop with iterative refinement, and result visualization. ## Full article daily.dev links to this article rather than hosting it.
