"Pinterest is experimenting with Chinese AI models to hone its recommendation engine. "We've effectively made Pinterest an AI-powered shopping assistant," the firm's boss Bill Ready told me. Of course, the San Francisco-based tastemaker could use any number of American AI labs to power things behind-the-scenes. But since the launch of China's DeepSeek R-1 model in January 2025, Chinese AI tech has increasingly been a part of Pinterest. Ready calls the so-called "DeepSeek moment" a breakthrough."
""They chose to open source it, and that sparked a wave of open source models," he said. Chinese competitors include Alibaba's Qwen and Moonshot's Kimi, while TikTok owner ByteDance is also working on similar technology. Pinterest Chief Technology Officer Matt Madrigal said the strength of these models is that they can be freely downloaded and customised by companies like his - which is not the case with the majority of models offered by US rivals like OpenAI, which makes ChatGPT."
Pinterest is experimenting with Chinese AI models to hone its recommendation engine. The launch of China's DeepSeek R-1 model in January 2025 sparked a wave of open-source models. Chinese competitors include Alibaba's Qwen, Moonshot's Kimi, and technologies under development at ByteDance. Open-source models can be freely downloaded and customised by companies, enabling in-house training and adaptation. Open source techniques used to train in-house models deliver roughly 30% higher accuracy than leading off-the-shelf models. Improved recommendations generated by these models can be up to ninety percent cheaper than proprietary models favored by US AI developers. These models are gaining traction across Fortune 500 companies.
