Open‑Source AI Strategy
Pinterest’s chief executive Bill Ready told investors that the company is actively evaluating leading off‑the‑shelf AI models against open‑source alternatives. In early testing, the open‑source models delivered “tremendous performance” for Pinterest’s visual‑AI use cases while dramatically lowering per‑token costs. Ready characterized the cost advantage as an “orders of magnitude reduction” compared with leading proprietary models. By fine‑tuning these open‑source solutions, Pinterest aims to support its core visual‑AI functions—including personalized recommendation engines, multimodal search that blends text and images, and ad‑targeting algorithms—without a significant increase in its cost structure.
The company already runs its own proprietary models, but Ready emphasized that the new open‑source approach will complement existing infrastructure and be deployed across a variety of product features. He noted that this strategy aligns with Pinterest’s broader goal of delivering value to users while keeping operating expenses in check. The emphasis on cost‑effective AI comes as the firm navigates a challenging revenue outlook, which contributed to a more than 21% drop in its stock price following the earnings release.
Future AI Initiatives
Beyond cost savings, Pinterest is expanding its AI capabilities into new consumer experiences. The firm recently launched the AI‑powered Pinterest Assistant, a conversational companion that can answer user queries, offer recommendations, and understand individual tastes based on boards, saved pins, and comparisons with similar users. Ready indicated that the assistant is part of a broader push toward “agentic commerce,” where AI systems could act autonomously on behalf of shoppers. However, he cautioned that Pinterest will monitor user demand before allowing the AI to execute purchases directly, noting that the platform already supports a “push‑button type buying” experience through its partnership with Amazon.
In addition, Pinterest is rolling out AI‑curated personalized boards that blend expert human curation with machine‑learning insights. These boards aim to enhance discovery and keep users engaged by surfacing content that matches their interests. Ready expressed confidence that these initiatives, combined with the cost efficiencies of open‑source AI, position Pinterest to strengthen its role in the visual discovery and shopping journey.
