The CEO of Commonwealth Bank of Australia (CBA), Matt Comyn, has raised concerns about the rising costs associated with using artificial intelligence (AI) for increasingly complex tasks, describing it as a significant management challenge for companies. He predicts that businesses worldwide will intensify their scrutiny of AI-related expenditures through 2026 due to the accelerated adoption of technology and the need to show tangible returns on investment. Comyn noted that while initial AI costs were modest, they can now escalate unpredictably as tasks become more sophisticated. He suggested that these rising costs could inadvertently help reduce the proliferation of low-value output, which he termed “work slop.”

Commonwealth Bank of Australia: Commonwealth Bank of Australia is Australia’s largest bank, offering retail, business, and wealth management services across the country. Its chief executive Matt Comyn has recently highlighted emerging challenges in corporate AI deployment, particularly as tasks increase in complexity.

AI Costs: The cost of using AI rises in less predictable ways as companies deploy the technology for complex tasks involving reasoning, tools, and additional context.
AI Output: Rising AI costs may have one upside by curbing the spread of low-value output, referred to as ‘work slop,’ in corporate environments.
Corporate Scrutiny: Businesses globally are likely to tighten scrutiny of artificial intelligence-related spending through 2026 as adoption accelerates and pressure mounts to demonstrate returns on investment.
