Microsoft swaps more Copilot traffic to in-house models to cut costs

Microsoft is shifting more Copilot traffic away from external OpenAI and Anthropic models toward its own MAI models, according to The Decoder.

The report says tens of thousands of weekly queries already run through Microsoft’s in-house models, with AI chief Mustafa Suleyman aiming to reduce or eliminate the cost of outside models.

For Copilot customers, the key question is whether lower provider costs come with any change in output quality, latency, or feature behavior.
