【Microsoft is working to integrate non-OpenAI models into 365 Copilot】According to Golden Finance reports, sources have revealed that Microsoft has been dedicated to increasing internal and third-party AI models to support its flagship AI product Microsoft 365 Copilot, diversifying the existing OpenAI foundational technology, and reducing costs. Microsoft is a major supporter of OpenAI, but this time it seeks to reduce its reliance on the AI startup, which is different from Microsoft's boasting in recent years about its access to OpenAI models. Sources said that in addition to training its own small models (including the latest Phi-4), Microsoft is also working to customize other open models to make 365 Copilot faster and more efficient. It is reported that the aim of this initiative is to lower Microsoft's operating costs for 365 Copilot and potentially pass on the savings to end customers.
