Microsoft deploys proprietary AI models in selected applications
Microsoft has begun replacing certain OpenAI and Anthropic models with its own MAI models in selected application features, particularly where cost-efficiency or data residency is critical.
What happened?
Microsoft has initiated a progressive transition of AI models within parts of its applications. Specific features that previously utilised models from OpenAI and Anthropic are now being redirected to Microsoft's proprietary MAI models. This transition occurs where cost considerations or requirements for data hosting within Microsoft's own infrastructure prove advantageous.

”Microsoft has begun swapping OpenAI and Anthropic models out for its own in-house MAI models in some app features where cost or data residency favours them, per Bloomberg.”
”The shift is incremental, OpenAI and Anthropic still handle most Copilot traffic, but it marks Microsoft steadily reducing a dependence it spent years and billions building, enabled by the 2025 renegotiation that freed it to build competing models.”
Why it matters
This shift indicates a strategy by Microsoft to reduce its dependence on external AI providers. By implementing in-house models, the company can optimise operational costs and exert better control over data residency, potentially leading to increased efficiency and security for certain services. This move follows a renegotiation of agreements, granting Microsoft greater freedom to develop competing AI models.
Who is affected?
Microsoft developers working on Copilot and other affected applications are directly impacted. Users of Microsoft products may indirectly benefit from improved performance or new features enabled by the proprietary MAI models. Enterprise clients using Microsoft services may benefit from potential cost savings and enhanced data control.
Impact on the EU
While Microsoft is a global corporation, data residency requirements within the EU may influence how and where these MAI models are deployed for European users. This could result in EU-based users being prioritised for features that benefit from data storage within EU borders.
What else you should know
Microsoft presented seven MAI models during its Build conference, including its first reasoning model alongside systems for image, voice, and transcription. MAI-Transcribe-1 is currently being tested in Teams and Copilot, while MAI-Image-2 is being rolled out across Bing and PowerPoint.
