Pinterest's AI Strategy Blends Open and Closed-Source Models - Business ...
Andre Rucker for BI 2026-04-30T17:42:00.716Z Pinterest's VP of product management said mixing open-source and closed-source AI models helped cut costs. The social platform's recent AI-enabled features combine OpenAI, Alibaba, and its own AI models. To support this approach, Pinterest invested in cloud infrastructure and an updated hiring strategy. In its pursuit of creating AI-supported tools for its users and advertisers, Pinterest leaders said it is actually shrinking part of its AI budget. As companies continue to spend on AI, they face pressure from investors to show returns on investment from this fast-evolving technology. One way to do that: Stretch investments by shrinking the budget needed for the systems that power AI features.Pinterest, the visual-first social media platform where users can save images to curate their ideas, is taking what it calls a "model-agnostic" approach to generative AI, said Vicky Gkiza, the company's vice president of product management. The strategy started in 2023 and involves combining Pinterest's proprietary AI models, developed by the company's software engineers, its closed-source models from Anthropic and OpenAI, and open-source models from Alibaba, said Gkiza.While closed-source AI models can quickly process large amounts of data, require little maintenance, and integrate instantly into a company's existing systems due to their pre-built nature, they're typically more expensive. Open-source models, meanwhile, are typically free to download, use publicly available data, and can be modified more deeply than closed-source offerings. However, they also require the expertise of software engineers who can build, maintain, and debug these highly customizable models.Lan Guan, the chief AI and data officer at Accenture, said companies are increasingly seeing value in a multimodal AI approach that balances performance and the cost of tokens, or the units of text AI models process. "This token cost is going to slow you down if you don't start managing them proactively," Guan told Business Insider. "Open-source will be a really good option."Gkiza walked Business Insider through how Pinterest bolstered its blended approach to generative AI through beta testing, an updated hiring strategy focused on software development expertise, and infrastructure investments.The techPinterest uses OpenAI's closed-source large language models to support some of its product features and relies on Anthropic's Claude, another closed-source A...

What Are Open-Source AI Models?Open-source AI models are artificial intelligence systems whose weights, architecture, and (in truly open cases) training code and data are made publicly available for anyone to download, run, modify, and deploy. Unlike proprietary models such as GPT-4 or Gemini, which are accessible only through paid APIs, open-source models can be self-hosted on your own infrastructure — giving you complete control over data privacy, customization, and cost.In 2026, three terms are used interchangeably but mean different things: Open-source means weights + training code + data are all public. Open-weight means the model weights are downloadable but training code or data may not be included. Open-access means the model can be used freely via an API but is not downloadable. Most models in this guide are ope...
