Microsoft has strengthened its monitoring of internal token usage and is gradually switching default workloads to OpenAI's GPT-5.6 Sol to reduce AI costs. Previously, an employee incurred approximately $28,000 in token usage costs over 28 days, prompting attention from senior management. In response, Microsoft has implemented stricter budget limits and mechanisms to identify abnormal spending, while reducing reliance on third-party AI tools such as Anthropic Claude.
