Commonwealth Bank of Australia CEO Matt Comyn warns that rising, non-linear costs for complex artificial intelligence tasks will force companies to increase scrutiny of their technology investments through 2026.

Key Points

• Commonwealth Bank CEO Matt Comyn identified unpredictable AI token costs as a significant emerging management challenge for global businesses.
• Corporate AI expenses are scaling non-linearly as models require more reasoning, context, and tool access for complex operational tasks.
• Businesses are expected to tighten oversight of AI spending to ensure clear returns on investment as adoption accelerates.
• Comyn suggested that higher costs may help reduce "work slop," or the proliferation of low-value AI-generated documents and presentations.
• Commonwealth Bank continues to prioritize AI integration, recently hiring a chief AI scientist and hosting an industry summit with OpenAI CEO Sam Altman.

Why it Matters

Rising AI costs could force a shift in corporate strategy, moving from experimental adoption to a more rigorous focus on measurable financial returns. This trend may limit the widespread generation of low-value content while compelling companies to justify the significant energy and infrastructure investments required for advanced computing.
