Australian Payments Plus (AP+), a central operator of Australia's payment and identity infrastructure, is leveraging ChatGPT Enterprise and Codex to streamline complex knowledge work. The organization, which manages critical systems used by millions, faces challenges in synthesizing vast amounts of technical information, including scheme rules and operational processes, into actionable decisions and member guidance. ChatGPT Enterprise assists employees in summarizing dense material, drafting communications, and structuring problems, significantly reducing time spent on information retrieval.

Codex, the next stage for AP+'s technical teams, is proving effective in accelerating investigations. One example involved reducing a multi-day manual timestamp inconsistency check across system logs to mere minutes. AP+ is also exploring Codex for security functions like threat modeling and vulnerability analysis. This application demonstrates AI's potential to speed up specialized technical investigations while maintaining human accountability for risk assessments and final decisions.

AP+'s adoption strategy emphasizes secure, governed tools and contextual learning. Internal data indicates 80% of employees reported increased creativity or improved work quality. The company has seen broad adoption, with over 300 custom GPTs and 1,000 Projects created. This approach allows AP+ to test product concepts more rapidly, simulating payment journeys and interactions to gather feedback earlier in the development cycle, ultimately reducing innovation risk before substantial engineering investment.
