Chatham Says It Cut Trade Validation From 30 Minutes to Under 4

OpenAI's own customer write-up says Chatham Financial is using Codex and GPT-5.6 to build technology and redesign workflows, cutting trade validation from 30 minutes to under four. The figure comes from the vendor's account of a customer's results. Compressing a validation step is easy to measure; whether the shorter process still catches the same problems is the question a number like that doesn't answer by itself.
