Microsoft is swapping out OpenAI's image-generating models for its own Microsoft AI technology in PowerPoint and Bing. The shift delivers 85% cost savings in PowerPoint while offering faster performance and higher quality, according to AI model chief Mustafa Suleyman. The move signals Microsoft's push toward self-sufficiency in AI as its models now power more than half of all Microsoft products.

Microsoft AI Takes Over Image Generation in Major Products

Microsoft is making a decisive shift away from external AI providers by replacing OpenAI image models with its own technology across widely used products including PowerPoint and Bing

The world's largest software maker has been developing AI models designed to compete directly with those from OpenAI and Anthropic. This strategic pivot aims to reduce dependency on external AI providers while dramatically cutting operational expenses. Microsoft AI models cost approximately 85% less to run in PowerPoint compared to OpenAI's technology, representing substantial savings as the company scales AI across its product portfolio

Cost Efficiency Drives Strategic Shift

While Microsoft currently receives free access to OpenAI models through its longstanding partnership, the company must still provide the expensive computing infrastructure to run these models

. By deploying more efficient image-generating models, Microsoft can realize significant savings on AI infrastructure costs. This economic imperative becomes particularly important as customers routinely generate and edit images in Microsoft apps, such as creating infographics in PowerPoint.

Suleyman noted that asking software to create an image is often one of the first AI prompts new users make, making it critical for the experience to be positive and performant

. Faster performance and lower costs directly translate to improved user retention, a key metric for Microsoft's AI strategy.

Broader Push Toward Self-Sufficiency in AI

The image model replacement is part of a wider initiative to reduce dependency on external AI providers. Bloomberg previously reported that Microsoft was beginning to replace OpenAI and Anthropic text models within widely used office apps. Microsoft AI models in Excel now perform on-par with OpenAI's GPT-5.6 for common tasks while being more cost-efficient

Microsoft AI models are now deployed in more than half of all Microsoft products and are being tested across the entire portfolio, Suleyman revealed. "It is a very strong showing, and we're going to continue to push extremely hard," he stated

This transition marks a significant evolution in Microsoft's AI strategy, moving from reliance on external partners toward building proprietary capabilities that offer competitive advantages in speed, cost, and quality. As Microsoft continues to integrate its own AI models across its product ecosystem, the company positions itself to control both the technology stack and the economics of AI deployment at scale.
