Westpac Banking Corp. is implementing a new strategy to manage artificial intelligence costs by tracking employee token consumption and routing tasks to the most cost-effective models. According to chief AI officer Dan Jermyn, the Australian lender aims to balance innovation with financial efficiency as firms globally face rising expenses from generative AI deployment.
How Banks Are Managing Generative AI Costs
Financial institutions are shifting from initial AI experimentation toward rigorous cost-management frameworks. Westpac is currently monitoring how its software development teams utilize advanced AI models, ensuring that complex tasks receive high-end processing power while simpler queries are routed to cheaper, more efficient alternatives, according to Dan Jermyn.
This approach addresses a broader trend among global executives who are increasingly scrutinizing the return on investment for AI tools. As companies scale their use of generative AI, the cumulative cost of tokens—the basic units of data processed by these models—can climb rapidly. By requiring staff to understand the “intricacies” of different tools, Westpac seeks to prevent unnecessary spending on high-cost models for basic tasks.
The Impact of Infrastructure Modernization
Westpac’s focus on AI efficiency coincides with its UNITE initiative, a long-term project designed to centralize disparate systems inherited from past acquisitions. According to Jermyn, this technological cleanup is essential for maximizing the operational utility of AI across the bank.
The bank’s financial reports highlight the urgency of these investments. Total technology spending at Westpac reached A$3.1 billion ($2.2 billion) for the fiscal year ending Sept. 30, a 13% increase from the previous year. This rise underscores the significant capital required to modernize legacy systems while simultaneously integrating cutting-edge generative tools.
Why Efficiency Is the New Competitive Advantage
The race to adopt AI is no longer just about access; it is about deployment speed and cost-efficiency. Jermyn noted that the primary competitive advantage lies in how effectively an organization manages its AI resources across the entire enterprise.
For providers like OpenAI and Anthropic, this shift in corporate behavior could lead to revenue pressure.
