Microsoft is reshaping its AI strategy for 365 Copilot by integrating in-house and third-party models, easing its reliance on OpenAI due to cost and speed concerns for enterprise users, according to sources.

Microsoft is reportedly looking to reduce its reliance on OpenAI for the AI models powering its Microsoft 365 Copilot assistant.

Microsoft is planning to integrate internal and third-party artificial intelligence (AI) models into its flagship AI assistant, Microsoft 365 Copilot. The move comes as the tech giant looks to reduce its dependence on OpenAI 's tech and save costs.

Microsoft and OpenAI have had something of a symbiotic relationship, with the former giving billions of capital to a startup AI lab and in return gaining early access to cutting-edge models that are now baked into Microsoft’s suite of productivity software.
