Microsoft Rethinks AI Strategy to Cut Costs and Burden, With Excel and Outlook Leading the Shift
To cut operational expenses and strengthen its internal AI capabilities, Microsoft has launched a major strategic shift in its core software suite. According to industry sources, the company is progressively integrating its proprietary MAI model into Excel and Outlook, phasing out its previous reliance on OpenAI and Anthropic.
These two flagship applications now process tens of thousands of AI tasks weekly using the MAI model. While this represents a fraction of Microsoft’s total AI usage, it signals a significant milestone in the company’s proprietary AI development. Mustafa Suleyman, head of Microsoft’s AI models, announced in June that the company is increasing MAI adoption to mitigate the high costs associated with third-party providers.
The substantial computing costs behind Copilot and other AI-enhanced office tools have long been a financial burden for Microsoft. Despite discounts from its partnership with OpenAI, this approach is not sustainable. By building its own models, Microsoft aims to secure control over the future AI landscape and avoid dependency on the pricing strategies of leading AI labs.
This strategy extends beyond Excel and Outlook. The MAI model is already deployed in GitHub Copilot. According to Suleyman, Microsoft plans to expand its proprietary transcription models in the coming months, integrating them into Teams and other products to build a more self-reliant AI ecosystem.
