Michigan dairy farmer Paul Windemuller built a local, multi-agent AI system using Gemini 3.6 Flash inside Google Antigravity to manage his farm. In 2014, Paul and Brittany started Dream Winds Dairy with 30 leased cows, which grew into a facility milking 260 Holsteins. As a 2024 Nuffield International Farming Scholar studying ag tech and AI, Paul’s operations generate continuous data streams from sensor collars, a local weather station, and an online portal for milk quality and shipments, but these systems operated in isolated software silos. To reclaim time spent manually merging spreadsheets, Paul built a system using a local, directory-based file-interface. When CSV data exports or photos of receipts, PDFs, and invoices are saved to a monitored folder, Gemini’s multimodal power extracts and merges metrics. A specialized multi-agent workflow includes an Orchestrator, Ingestion Agents, Analysis Agent, and Reporting Agent to transform raw files into a cohesive business overview. Paul aims to empower independent farmers, noting that daily agentic workflows requiring continuous reasoning had been too expensive for small businesses, but Gemini 3.6 Flash helped make his daily operation more cost-effective.
