Case Study: eBay accelerates AI-driven recommendations with Google Cloud Platform

eBay accelerates its AI-driven recommendation engine with Vertex AI

eBay, one of the world’s largest online marketplaces with more than 1.9 billion listings, wanted to accelerate its AI-powered recommendation engine and improve how shoppers discover relevant products. To support its existing on-premises ML stack, eBay turned to Google Cloud Platform, specifically Vertex AI and Vector Search, to add more advanced AI capabilities without replacing its entire workflow.

Google Cloud Platform helped eBay build a hybrid setup linking its data center to Google Cloud, then trained custom models on Vertex AI and indexed embeddings in Vector Search for faster experimentation. The result was a smoother, self-service onboarding process for new vector indexes and a pace of iteration that was four times faster, enabling new recommendation features and reducing friction for both buyers and sellers.
