【Microsoft is working to add non-OpenAI models to 365 Copilot】According to reports from Jinse Finance, Microsoft has been committed to increasing internal and third-party AI models to support its flagship AI product, Microsoft 365 Copilot, diversifying existing OpenAI foundational technologies and reducing costs. Microsoft is a major supporter of OpenAI, but this time, Microsoft seeks to reduce its dependence on this AI startup, which is different from Microsoft's bragging about its access to OpenAI models in recent years. Sources say 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 understood that the purpose of this move is to reduce the costs of running 365 Copilot for Microsoft and potentially pass the savings on to end customers.
