Microsoft launches new in-house AI models it says cut costs up to 89% versus OpenAI

Microsoft AI unveiled two in-house models, MAI-Image-2.5-Pro and MAI-Voice-2-Flash, now in public preview.

The company says the models are already powering products including Bing, PowerPoint, OneDrive, Dynamics 365, Excel, GitHub Copilot, and Azure.

Microsoft claims major cost savings, with up to 84% lower GPU cost in PowerPoint and up to 89% less in Dynamics 365 Contact Center versus OpenAI-based systems.

The move signals Microsoft is putting more of its AI stack on its own models to cut costs and reduce reliance on OpenAI.
