Merge, a company that OpenAI cites as a customer, is using the company's tools across both product engineering and business operations. According to OpenAI's account, Merge uses GPT-6 Astra, ChatGPT and Codex to review product code, while the same tools support its marketing work. Its teams also use AI for less technical tasks, including planning executive dinners and preparing sales updates. The breadth of the reported use is the more notable detail. Code review and marketing support sit alongside administrative and reporting work, which suggests the tools are being applied across the company rather than confined to one team or feature. The available description does not quantify productivity gains, cost savings or error rates, so the claims remain the vendor's account and are difficult to assess independently. For Australian businesses and professionals, this case study changes little on its own. It is one vendor's description of internal use and does not alter pricing, regulation or legal obligations. The uses it describes are low-stakes and easy to pilot, such as drafting marketing copy, preparing meeting briefs or using AI to assist code review under existing engineering oversight. Any tool that receives customer or staff personal information should be assessed against the Privacy Act 1988 before that data is entered, and the cost of ChatGPT or Codex seats should be weighed against time savings that the team has measured itself.
