Microsoft is reportedly routing its own products to cheaper in-house Microsoft AI (MAI) models when they match frontier quality on specific tasks, aiming for substitutability rather than relying solely on external frontier models. The company's strategy focuses on the surrounding system—evaluations, memory, tools, context, and workflows—to provide lasting advantage, ensuring product improvement even if underlying models are replaced.
Microsoft's strategy makes AI models a replaceable commodity, shifting infrastructure demand towards internal MAI models and reducing reliance on external frontier providers.
