Microsoft Replaces OpenAI Image Models In PowerPoint
Microsoft is replacing OpenAI image models used in PowerPoint and Bing with its own in-house image generation technology, marking a shift in how the company delivers AI-created visuals across major consumer and productivity products.
The change affects image creation features tied to Microsoft services, including PowerPoint and Bing. Recent reports describe Microsoft moving away from OpenAI’s image models in these products and rolling in Microsoft-built alternatives as part of a broader push to rely more on its own AI systems.
Several outlets have identified Microsoft’s internal image generator as “MAI-Image-2,” describing it as the model Microsoft intends to use in place of OpenAI-related image technologies in PowerPoint and Bing. Microsoft has also announced new variants of its in-house AI models, reflecting what one report characterized as a minor shift away from OpenAI.
The move matters because it highlights Microsoft’s accelerating effort to build and deploy its own foundation models inside products used by hundreds of millions of people. PowerPoint sits at the center of Microsoft’s Office productivity suite, and Bing is a flagship consumer service. Changing the underlying image model can affect how visuals are generated, how features are delivered, and how Microsoft manages performance and cost across its AI offerings.
One report said Microsoft’s in-house models cut costs significantly versus OpenAI, and other coverage framed the decision as part of Microsoft’s push toward greater AI autonomy. That combination—control of core model technology and potential cost advantages—can influence how quickly Microsoft expands image generation features, how it prices AI capabilities, and how tightly those tools can be integrated into Microsoft’s broader ecosystem.
The replacement also underscores the evolving relationship between Microsoft and OpenAI. Microsoft has been a high-profile partner and major backer of OpenAI, and OpenAI models have been widely associated with Microsoft’s AI product strategy. Swapping out image models in marquee products is a tangible example of Microsoft diversifying the model providers and technologies that sit underneath its user-facing AI experiences.
Next steps will center on implementation across the affected products. Microsoft will need to roll the technology change through PowerPoint and Bing’s image creation workflows and ensure the new model meets product requirements at scale. Microsoft will also likely continue releasing additional internal model variants, as indicated by recent announcements, as it builds a broader lineup of in-house AI systems.
The shift positions Microsoft to deliver AI-generated images in PowerPoint and Bing using technology it controls end-to-end, signaling a more self-reliant approach to powering key features across its platforms.
