Microsoft internally shared that it is using AI to save hundreds of millions of dollars, even as the tech giant lays off thousands of workers. For customer service workers, Althoff noted that Microsoft saved more than $500 million last year in call center productivity and boosted employee and customer satisfaction with the interactions. On the sales side, Microsoft employees are using the company's Copilot AI assistant to yield 9% more revenue by helping salespeople find more leads and close deals faster, Althoff said. Microsoft's AI coding tool, GitHub Copilot, is a market leader, with 15 million users. In June 2024, before the recent layoffs, Microsoft reported having a total global workforce of 228,000 employees, with 126,000 located in the U.S.
