Wayfair uses multimodal AI to detect fraudulent imagery in its product catalog in real time. This system is part of Wayfair's Trust and Safety operations.

Wayfair's CTO Fiona Tan described this capability on the company's Q3 2025 earnings call, as summarized by Constellation Research. The system uses multimodal AI — meaning it processes both images and other data types together — to flag fraudulent or policy-violating product images as they appear. The exact technical architecture, vendor, and scale of deployment have not been disclosed in primary sources beyond this description. Wayfair has also described a 'Melange' customer journey embedding system used for fraud and policy-abuse detection, based on its own tech blog.
