According to a statement from the companies, Pinterest plans to invest approximately $4 billion in AWS cloud infrastructure by 2031, AmazonNews reports. This agreement is already being called the largest infrastructure deal in the platform’s history.
The key goal of the partnership is to strengthen Pinterest’s AI capabilities, including the development of visual search, recommendation systems, and multimodal models. The company intends to make more active use of Amazon Web Services’ cloud infrastructure, as well as specialized Trainium and Graviton chips, which are optimized for training and running large artificial intelligence models.
Pinterest emphasizes that expanding this collaboration will allow for more flexible management of computing resources and reduce the cost of training models as their complexity increases. This applies to both the company’s in-house developments and the use of open-source models.
According to the company’s technical leadership, the focus on AI should directly improve the user experience—making recommendations more accurate and visual search more “intuitive” and personalized. Special emphasis is also placed on the advertising ecosystem: more advanced algorithms are expected to improve targeting efficiency.
The partnership between the companies is not new—Pinterest has been working with AWS since 2010. However, the current agreement effectively takes the collaboration to a new level: from basic cloud infrastructure to deep integration of AI computing and large-scale model training.
Against the backdrop of audience growth—over 600 million monthly users—Pinterest is intensifying its focus on its own AI products. One of the latest is Pinterest Assistant, a tool for interactive search and selection of visual content.
The new investment program effectively marks a strategic pivot: Pinterest is positioning AI not as a supporting technology, but as the central foundation for the platform’s future growth.
