Commonwealth Bank Flags Rising AI Costs for Corporate Australia
Synopsis
Commonwealth Bank of Australia CEO Matt Comyn has warned that AI costs could rise sharply as businesses increasingly deploy artificial intelligence for more advanced and complex tasks. Speaking at a conference in Sydney, Comyn said companies are likely to closely scrutinise AI spending through 2026 as token processing costs become less predictable and pressure grows to prove returns on investment. He said modern AI systems involving reasoning and broader context processing are driving expenses higher than expected. Comyn also criticised the rise of low-value AI-generated “work slop” across workplaces as corporate AI adoption accelerates globally.
The cost of artificial intelligence could soar as companies use it for ever-more complex work, says Commonwealth Bank of Australia chief executive Matt Comyn.

CBA Flags Higher Costs of AI for Businesses
Comyn, speaking to an Australian Financial Review conference in Sydney, said that companies around the world will likely become less tolerant with AI-linked expenses as adoption speeds up and calls increase for tangible returns from investments.
The cost challenge is coming out because businesses pay for AI services by the token, which are actually words and text you use and data you process, he said. Although early use cases for AI stayed pretty low-cost due to the ease of the tasks performed, costs are beginning to become less predictable as models handle more complex reasoning and larger context.
Increased costs from heavier workloads driven by complex AIs
This reasoning, tool access and wider context processing means token prices are being hit harder than many firms had realised possible, Comyn said of modern AI systems.
He warned the ramp-up of AI costs is no longer a linear issue, and this could be a big management problem for companies in the next year. He also raised wider concerns over disruption to the workforce and the huge energy and water demands associated with sprawling data centres that support AI systems.
CBA expands artificial intelligence push but warns not to have “slop on the work”
CBA has been one of the most frequent corporate AI adopters in Australia. The bank recently held an AI summit with Sam Altman and hired what it called Australia's first chief AI scientist at a bank last week.
Rising AI costs may at least help deter businesses from unleashing a flood of knee-jerk low-value AI work slop, Comyn said. He said AI can quickly churn out analysis, presentations and documents, but cautioned companies must remain focused on output that is substantive and valuable.
