McKinsey deploys email alerts to curb consultants' AI token spending
McKinsey now emails staff when their AI usage exceeds set thresholds, aiming to improve cost efficiency without limiting access.
McKinsey has introduced a firmwide email notification system that flags consultants whose AI token consumption rises sharply, according to Debasish Patnaik, leader of QuantumBlack in the UK. The alerts are designed to increase transparency and teach staff how to achieve the same outcomes with fewer tokens, rather than to restrict tool usage. By May 2026 the firm processed roughly five trillion AI tokens each month, with a small group of users responsible for the majority of consumption.
Additional controls such as an internal AI gateway, circuit breakers, and caching are also in place to manage costs. Patnaik notes that internal AI spending remains manageable and that the firm continues to promote adoption while monitoring for potentially excessive use. Similar cost-control measures are being adopted by other consulting firms.
