Copilot goes cheap as Microsoft phases out OpenAI and Anthropic models to cut costs

Microsoft is replacing AI models from OpenAI and Anthropic with its own MAI models in products like Excel and Outlook. Currently, tens of thousands of queries per week are processed through these models, as AI chief Mustafa Suleyman aims to eliminate the cost of external models. This shift is part of Microsoft's strategy to cut costs, potentially impacting Copilot customers who may experience reduced performance at the same price. This approach emphasizes the company's commitment to internal models, which could reshape the AI landscape in its products.
