Could you explain why your AI bill rose and what the business got in return? I asked Jim Rowan, US Head of AI at Deloitte, because a total spend figure tells a finance team how much it paid, but gives it little help deciding which work to expand. In Deloitte's State of AI in the Enterprise survey, 71 percent tracked total AI interface and API spend, 51 percent tracked token volume, and 44 percent tracked the cost per unit. Jim suggests looking at what it costs to finish a task to an acceptable standard.
We talk about what surrounds the model: the tools it can call, the information it can retain, and the permissions it needs to work with company systems. Jim gives a simple example. An email connection can let an agent read messages, draft a reply or send on someone's behalf. Each step carries different consequences. Getting that decision right can take longer than choosing the model, especially when an agent needs access to a system the company has relied on for decades.
Jim also explains why he'd start with a company's existing approval limits before giving an agent authority to act. The same payment might require review at a small company and fall within routine approval limits at a larger one. Deloitte's survey puts that discussion in context: 40 percent reported allowing AI to execute decisions or actions without human approval to at least a moderate degree, while 23 percent reported unclear accountability for negative outcomes. Those are separate findings and tell us nothing about how much the groups overlap.
We finish with a question for anyone tempted to swap models after the next release. Does it do your work better, and is the improvement worth the cost of testing and switching? Deloitte's survey also found that 28 percent reported revenue gains from AI, up from 20 percent in the previous edition. That's encouraging, although reported revenue gains do not establish that a project paid for itself. I'd love to hear your experience. What do you measure to decide whether an AI workflow deserves a bigger budget?
