Pinterest CEO Bill Ready highlighted the potential of open source AI during an earnings call, emphasizing its role in reducing costs while expanding visual AI applications. The company uses AI for personalized recommendations, multimodal searches combining text and images, ad targeting, and recently introduced the AI-powered Pinterest Assistant for product discovery. Investors are particularly interested in how Pinterest plans to leverage agentic commerce, where AI acts autonomously for users, especially as the company anticipates a weaker holiday shopping season due to external factors like tariffs. Ready pointed out that Pinterest is testing off-the-shelf AI models against open source alternatives, reporting significant cost reductions without sacrificing performance. He stated that their initial tests showed open source models delivered similar results at a fraction of the cost compared to proprietary options. Pinterest plans to integrate these open source models into its operations, which could help mitigate financial pressures, especially as fourth-quarter revenue projections fall short of analyst expectations, with estimates between $1.31 billion and $1.34 billion. In discussing future strategies, Ready noted Pinterest's existing “push-button type buying” feature through its partnership with Amazon and mentioned the company’s efforts to enhance user experience with the Pinterest Assistant. This AI companion aims to provide personalized advice based on user preferences and behaviors. Furthermore, Pinterest is rolling out AI-curated boards that blend human expertise with machine learning, supporting the company's goal of guiding users through their shopping journeys.
