Microsoft's top AI boss has a message for engineers using GitHub Copilot
Microsoft is implementing stricter internal controls on AI token usage for its engineers to manage rising operational costs. While the company remains committed to an AI-first strategy, it is shifting focus from raw volume to optimizing the impact of each token used.
Why it matters
This highlights a growing trend where enterprises are moving from experimental AI adoption to managing the significant, often underestimated, financial costs of autonomous agentic tools.
Microsoft has spent three years telling the world to use more AI. This week it told its own engineers to use it more carefully. In an internal email to his CoreAI organisation, executive vice president Jay Parikh wrote that "tokenmaxxing is not what we are optimizing for" — and backed the line with policy. OpenAI's cheaper GPT-5.6 is now the default model for internal use, every Microsoft division has an AI token budget target, and employees can pull up a dashboard showing exactly what their own AI habit costs the company.The memo was first reported by 404 Media, which obtained it from a Microsoft employee who asked not to be named. The numbers inside are the eye-catching part. Microsoft's internal Copilot guidelines say many engineers spend anywhere from a few hundred dollars to a few thousand dollars a month on tokens.
