Pinterest Commits $4B to AWS for AI Infrastructure

Pinterest announced a planned $4 billion commitment to AWS through 2031, the largest infrastructure investment in the company's history. The deal builds on a partnership dating back to 2010 and aims to accelerate AI innovation powering visual search and discovery for more than 600 million monthly users.

Pinterest makes its largest infrastructure commitment to date. The visual discovery platform plans a $4 billion commitment for cloud services through 2031. This is the largest infrastructure deal in Pinterest's history and extends a relationship that began in 2010.

Together the companies have optimized one of the largest-scale data lakes on AWS. The agreement supports Pinterest's growth across AI model training, inference and platform infrastructure.

AWS custom silicon accelerates Pinterest's AI models. Pinterest will use AWS Trainium to host and run large language models and vision-language models. These power personalized visual search and AI-assisted discovery.

The company is expanding its use of Graviton processors which already power roughly a third of its compute infrastructure. Graviton will run more of the systems supporting discovery for hundreds of millions of people every month.

AI advancements enhance visual discovery and personalization. Pinterest has long applied AI to visual discovery and personalization powered by its proprietary Taste Graph. The platform helps users move from open inspiration to personalized actionable results from finding a recipe to shopping a look to planning a home renovation.

The company has accelerated this with advances in recommendation systems and multimodal models evolving from traditional retrieval methods to transformer-based generative models. Most recently Pinterest launched Pinterest Assistant for multi-turn conversational discovery powered by open-source vision-language models optimized for scale.

Infrastructure modernization accompanies the AI investment. Pinterest is transitioning from traditional EC2-based environments to a Kubernetes-based architecture on Amazon Elastic Kubernetes Service. The migration is expected to improve developer velocity operational reliability and infrastructure efficiency across Pinterest's global platform.

Pinterest's CTO details the benefits of the expanded AWS partnership. "Pinterest is heavily investing in AI to make discovery more personal, visual, and actionable for the hundreds of millions of people who use our platform every month," said Matt Madrigal, chief technology officer at Pinterest. "This expanded commitment with AWS gives us the compute flexibility, hardware optionality, and infrastructure efficiency to accelerate our AI vision for the next generation of visual discovery on Pinterest. This strategic partnership will help accelerate AI innovation at Pinterest, improving both our consumer experience and advertiser performance by advancing our proprietary models and our use of open-source models."
