What's happened
EY has rolled out an internal, invisible router to steer employees toward cost-effective AI models, reducing token waste by about 60% since April. The move follows a broader push by firms to monitor AI token usage as model prices shift to per-token billing. A majority of leaders are now budgeting controls on AI spending.
What's behind the headline?
Key implications
- EY’s router directs user prompts to the most cost-effective model without altering the user experience.
- Token-based pricing is pressuring firms to balance capability with cost, prompting governance and budgeting for AI use.
- The approach may become a common control mechanism across enterprises, especially in tax, risk, and other specialist workflows.
What this signals for readers
- The biggest cost in AI deployments is not model power but choosing the right tool for the task.
- Enterprises will increasingly deploy routing and governance to prevent token waste and manage budgets.
- As token prices rise, workers will see real changes in access to certain models depending on role and need.
How we got here
EY has implemented department-specific AI routers to curb token costs and extend the value of AI investments. The approach is part of a wider trend as companies shift from chasing the most powerful models to optimizing cost efficiency amid rising token-based pricing.
