Microsoft’s push to cut costs following thousands of layoffs has reached its premier artificial intelligence (AI) partnerships, a report has said, claiming that the tech giant is beginning to “dump” models from OpenAI and Anthroth its own internally built AI.Citing a person familiar with the matter, Bloomberg reported that tens of thousands of AI prompts within Microsoft Excel and Outlook are now being quietly handled each week by Microsoft’s home-grown “MAI” models. Previously, these spreadsheet and applications relied on technology developed by OpenAI and AnthroWhile internally handled tasks represent a relatively small portion of Microsoft’s total AI footprint, the shift proves the company is making major strides in building highly competitive artificial intelligence (AI) at a fraction of the cost.
Microsoft AI CEO Mustafa Suleyman’s June ‘warning’
The move follows a clear warning issued in June by Microsoft’s AI division chief, Mustafa Suleyman, who stated that the company was actively trying to reduce its financial dependence on Anthropic.Every time a user asks an AI assistant to write an email or analyse data, it consumes massive quantities of “tokens” – the basic unit of measurement for AI computing power. Currently, Microsoft’s workplace assistant, Copilot, consumes these tokens at an extraordinary rate. While Microsoft currently enjoys steep discounts on this computing power due to its multi-billion dollar partnership with OpenAI, executives know that special pricing agreement won’t last forever, the report said. Suleyman’s team is working to ensure Microsoft isn’t left at the mercy of outside AI labs’ pricing models.
Eliminating the outside costs
At its annual Build developer conference in June, Microsoft debuted seven new in-house AI models. The company claims one of its new models can match the coding capabilities of Anthropic’s highly popular, prior-generation Opus 4.6 model – but at a significantly lower operational cost.“We pay a lot of money to Anthroost,” Suleyman stated at the conference.The rollout of Microsoft’s MAI models is already expanding beyond basic office work, the report noted. The home-grown tech is now available within GitHub Copilot for software developers, and Suleyman confirmed that a Microsoft-built voice transcription model will be integrated into Microsoft Teams videoconferencing and other core products in the coming months.
