Microsoft Moves Toward In-House AI Models
Wealthari
Microsoft is increasingly deploying its own proprietary AI models to reduce costs and gain better control over performance across its product ecosystem.Summary
Microsoft is shifting its AI strategy by integrating internal MAI models into products like Excel and Outlook, reducing its heavy reliance on third-party providers like OpenAI and Anthropic. Introduced at Build 2026, the new MAI-Thinking-1 and other models offer comparable performance at significantly lower costs. To manage this, Microsoft uses its Foundry platform for intelligent model routing, which dynamically selects the most efficient model for specific workloads. While the company is prioritizing its own technology, it maintains a hybrid, multi-model ecosystem, continuing to support external models for specialized enterprise needs.
