According to a case study published by OpenAI, Stampli, an accounts payable company, used ChatGPT Work and Codex to reduce the hours spent on a launch by 68%. The project had a fixed deadline, and design resources were already assigned elsewhere, which pushed the team to find an alternative approach.
The tools allowed the team to compress what would have taken weeks of production into days. The write-up highlights how AI coding and work assistants can be applied to real-world launch logistics, rather than just isolated coding tasks.
Because this is a single vendor-published account, there is no independent data or comparison to other methods. The reported figures come directly from OpenAI's own case study, so they should be read as a company-provided example rather than a neutral benchmark.
