OpenAI Chief Financial Officer Sarah Friar said the artificial-intelligence company’s relationship with major investor and cloud provider Microsoft is “changing,” but emphasized that the software giant will remain a crucial partner “for years to come,” according to remarks aired on CNBC. Microsoft has invested billions of dollars in OpenAI and supplies the computing infrastructure that powers the startup’s large-language models, while incorporating OpenAI technology across its product suite. Friar did not specify how the collaboration is evolving, but her comments suggest the two firms are adjusting the terms of their alliance as demand for generative-AI services grows.
