Pinterest inks $4 billion AI deal with AWS, the largest infrastructure commitment in its history

Pinterest has long applied AI to visual discovery and personalization. Powered by its proprietary Taste Graph, Pinterest helps users move from open inspiration to personalized, actionable results—from finding a recipe to shopping a look to planning a home renovation. In recent years, the company has accelerated this work with major advances in its recommendation systems and multimodal models, evolving from traditional retrieval methods to transformer-based generative models.
