Microsoft Tightens Employee AI Budgets After Individual Bill Reaches $28,000

Microsoft is reportedly tightening its employees' AI token budgets and monitoring usage after discovering high individual spending, including one employee who ran up a $28,000 bill in 28 days. To control costs, the company is also transitioning its default internal workloads to OpenAI's GPT-5.6 Sol. This move highlights the soaring operational costs associated with generative AI, prompting even major AI developers like Microsoft to implement strict cost-control measures. It reflects a broader industry trend where enterprises must balance AI productivity gains against substantial infrastructure and API expenses. While the median monthly AI spend among surveyed US employees was $300, the CoreAI department saw a median of $975, with one individual spending $16,000. Microsoft is also discouraging the use of third-party AI tools like Anthropic's Claude for coding tasks to further optimize expenses.
