Microsoft has replaced artificial intelligence models from OpenAI and Anthropic with its own MAI technology in several Office applications, including Excel, Outlook, and GitHub Copilot. The move is aimed at reducing costs associated with licensing third-party AI models.

The company has integrated MAI, its in-house AI system, into these productivity tools to handle tasks such as data analysis in Excel, email management in Outlook, and code suggestions in GitHub Copilot. This shift allows Microsoft to rely less on external providers and leverage its own AI capabilities.

By adopting MAI, Microsoft expects to lower operational expenses while maintaining or improving the performance of AI features in its software suite. The change affects millions of users who rely on these tools for daily work.

The decision follows a broader trend among tech companies to develop proprietary AI solutions to reduce dependence on external vendors and gain more control over their technology stacks. Microsoft's move signals a strategic pivot toward self-sufficiency in AI.
