## Scaling AI with Custom Silicon

Pinterest has long relied on AI to refine its recommendation systems and personalize user experiences. Recent advancements include the development of multi-turn conversational discovery via Pinterest Assistant, powered by open-source vision-language models. To support these demanding workloads, Pinterest is turning to AWS's specialized hardware.

The company plans to use AWS Trainium for large language and vision-language models that drive AI-assisted discovery. Pinterest is also increasing its use of Graviton processors, which already power approximately one-third of its compute infrastructure. This strategic shift targets enhanced efficiency and performance for AI-driven features.

According to Matt Madrigal, CTO at Pinterest, this commitment provides the necessary compute flexibility and infrastructure efficiency to advance their AI vision. He noted that the partnership will improve both consumer experience and advertiser performance.

The agreement also supports Pinterest's ongoing infrastructure modernization, including a transition to a Kubernetes-based architecture on Amazon Elastic Kubernetes Service (EKS). This move is expected to boost developer velocity and operational reliability.

Dave Brown, SVP of AWS Compute & ML Services, stated that AWS is the optimal environment for large-scale AI development, emphasizing their commitment to accelerating Pinterest's innovation.
