A report describes a GRPO fine-tune of a 9B open-source model that outperformed multiple frontier model configurations on the same catalog-review workflow, using the same tools, images, and scoring setup. The result was achieved at about $0.50 per 1,000 listings, significantly cheaper than the frontier alternatives tested.
