Pinterest announced a planned $4 billion commitment to Amazon Web Services through 2031, marking the largest infrastructure investment in the company’s history. The agreement expands a partnership that began in 2010 and is designed to support Pinterest’s next phase of growth in artificial intelligence, machine learning, and cloud infrastructure.
The visual discovery platform, which serves more than 600 million monthly users worldwide, plans to leverage AWS technologies including Trainium and Graviton chips to train and run AI models at scale. These models power Pinterest’s visual search, recommendation systems, and personalized discovery experiences that help users find inspiration, shop products, plan projects, and explore ideas across a wide range of interests.
Pinterest has increasingly integrated AI into its platform through innovations such as its proprietary Taste Graph, advanced recommendation systems, multimodal AI models, and the recently launched Pinterest Assistant. The assistant introduces multi-turn conversational discovery capabilities to Pinterest’s visual search experience through optimized vision-language models.
Under the expanded partnership, Pinterest plans to deploy AWS Trainium to host and operate large language models and vision-language models that drive personalized recommendations and AI-assisted discovery. The company is also increasing its use of AWS Graviton processors, which already power approximately one-third of Pinterest’s computing infrastructure.
Beyond AI development, the agreement supports a broader modernization effort across Pinterest’s technology stack. The company is transitioning from traditional EC2-based environments to a Kubernetes-based architecture built on Amazon Elastic Kubernetes Service (EKS). Pinterest expects the migration to improve operational efficiency, platform reliability, and developer productivity as it continues scaling globally.
The companies said the partnership will provide Pinterest with greater computing flexibility, infrastructure efficiency, and hardware options to accelerate innovation in both consumer experiences and advertising performance.
