Australian Payments Plus (AP+), the operator of payments and identity infrastructure in Australia, has deployed ChatGPT Enterprise across the company and is expanding use of Codex for product, engineering and technical workflows. AP+ says the tools help employees move through large volumes of technical and regulatory information more quickly while preserving accuracy and accountability.
Why they deployed the tools and where they are used
AP+ teams work across scheme rules, technical specifications, member obligations, operational processes, cybersecurity and regulatory expectations. That combination makes knowledge work complex: staff regularly need to synthesise context and turn technical material into clear decisions, documents and member guidance. ChatGPT Enterprise is used to reduce the time needed to produce a first useful version so experts can focus on judgment, clarity and quality.
Practical uses include:
- Summarising and structuring complex material.
- Drafting data-driven member communications.
- Turning meeting notes into concise summaries and workshop inputs into decision materials.
- Clarifying dense design documents and improving draft communications before expert review.
According to AP+ internal data, 77% of surveyed employees reported saving hours each week by using ChatGPT, and 80% said it helped them be more creative or improved work quality.
Codex for technical investigations and product simulations
AP+ technical teams use Codex to investigate complex issues across payment systems. In one reconciliation case, Codex helped trace a subtle timestamp inconsistency across system logs and reconciliation data; what had required days of manual investigation was resolved in minutes.
In product development, Codex has shortened the time to produce working simulations. AP+ reports being able to build functioning payment and interaction simulations in one day, rather than the days or weeks previously required. More realistic early-stage testing matters in payments because customer behaviour can depend on timing, authentication prompts, device interactions and transaction flows.
AP+ is also exploring Codex use in security workflows—threat modelling, vulnerability analysis, alert triage and improving visibility across interconnected systems.
Adoption, governance and human accountability
AP+ staff have created more than 300 custom GPTs and over 1,000 Projects, reflecting broad internal adoption. The organisation emphasises that AI is used as a support tool rather than a replacement: human experts remain accountable for risk decisions, validation and response.
AP+ frames its experience as a practical example for regulated organisations seeking to scale AI responsibly. By embedding ChatGPT Enterprise into daily work and expanding Codex usage, AP+ aims to accelerate complex knowledge work while keeping expert review and responsible practices central.
Summary
AP+ reports that ChatGPT Enterprise and Codex have sped up many aspects of its knowledge and technical work—improving summaries, communications and the pace of technical investigations and simulations—while maintaining human oversight and accountability.
