Open source models
Pinterest, Inc. discusses open source models primarily in the context of their AI strategy and cost management, highlighting a careful balance between performance, innovation, and operational efficiency.
AI Capability and User Experience
Pinterest emphasizes that their proprietary AI models are already embedded within their platform, powering all ads and core AI-driven features. However, when broader large language model (LLM) capabilities are required, they actively perform "side-by-side testing" comparing leading off-the-shelf proprietary models against open source models. This suggests a rigorous evaluation process to optimize both technical performance and cost efficiency.
Cost Advantage and Performance
The company reports "tremendous performance" from open source models in early testing, especially for Pinterest-specific use cases such as visual AI. They highlight that fine-tuned open source models deliver comparable performance to proprietary ones but at an orders of magnitude reduction in cost, particularly in per-token costs. This aligns with their broader objective to maintain or improve user experience while managing the infrastructure expenses that come with AI features.
Strategic Cost Management
Pinterest conveys a clear message that integrating open source models is part of their cost control approach:
"we are just getting tremendous performance from open source models... at a fraction of the cost of the larger model providers"
This cost efficiency supports their long-term margin targets (30% to 34% adjusted EBITDA margin over 3 to 5 years), indicating that AI deployments—especially those leveraging open source technology—are viewed as investment opportunities with a high return on investment (ROI) and immediate monetization potential.
Monetization Focus
The company stresses that AI enhancements, including those powered by open source models, are designed to directly support monetization without a long delay:
"we apply AI use cases sort of directly in service to monetization, where we see immediate revenue lift"
Broader AI Initiatives
The mention of their new Pinterest Assistant and ongoing investments in AI-powered user experiences indicates a commitment to maintaining leadership in visual search and discovery, with open source models potentially playing an expanding role:
"...particularly across AI, that power user experiences, including our new Pinterest Assistant, which we believe will help keep us on the leading edge in visual search and discovery"
Pinterest views open source models as a strategically valuable tool that complements their proprietary AI capabilities by providing:
Their approach indicates a pragmatic and data-driven AI strategy, where open source models serve both as a cost-effective alternative and an enabler of innovation in user engagement and monetization.
Relevant excerpt:
"We are constantly doing side-by-side testing between both the leading off-the-shelf proprietary models and open source models. And one of the really, really interesting things that we're seeing is that we are just getting tremendous performance from open source models... we’re seeing orders of magnitude reduction in costs with comparable performance using fine-tuned open-source models versus leading off-the-shelf proprietary models. So going forward, we think open source can be applied to many more of our use cases and at a fraction of the cost of the larger model providers."

Pinterest details a model-agnostic AI strategy that combines in-house compact models, post-trained open-source models, and selective third-party options to power personalized discovery and shopping. The company emphasizes cost, customization, and control with secure on-site deployment, while reframing engagement metrics beyond MAU—highlighting UCAN signals like searches and boards created as the more informative indicators of resonance.
