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 has been working on adding internal and third-party artificial intelligence models to power its flagship AI product Microsoft 365 Copilot, in a bid to diversify from the current underlying technology from OpenAI and reduce costs,

The effort is said to focus on the tech giant’s Microsoft 365 Copilot product. It’s an artificial intelligence assistant that ships with the eponymous productivity suite. Microsoft is reportedly working to integrate custom and open-source artificial intelligence models into the assistant, which is currently powered by technology from OpenAI.

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.

When Microsoft announced 365 Copilot in March 2023, a major selling point was that it used OpenAI's GPT-4 model. Microsoft is also seeking to reduce 365 Copilot's reliance on OpenAI due to concerns about cost and speed for enterprise users, according to the sources, who requested anonymity to discuss private matters.
