Microsoft Reportedly Replacing OpenAI Image Models in PowerPoint and Bing

Bloomberg reports that Microsoft is replacing OpenAI image-generation models used in products including PowerPoint and Bing. The available source summary does not identify the replacement models, migration schedule, or comparative performance data. If confirmed, the move would indicate a broader effort by Microsoft to reduce dependence on a single model supplier and expand its use of internally developed or multi-provider AI systems across consumer and productivity products. The report concerns product infrastructure and vendor strategy, rather than a publicly documented model benchmark.
