Gilbert + Tobin's governed AI adoption

Gilbert + Tobin introduced ChatGPT Enterprise in operations and expanded its use to marketing, business development, recruitment, finance, technology, and parts of its legal practice. OpenAI's September 2026 customer story reports that 87% of enabled seats were active as of June 2026. The firm uses role-specific enablement and controls on data handling, access, and output review; the article does not establish an independent comparison group for its reported gains.

Gilbert + Tobin says a recruitment research task fell from roughly four hours to 20 minutes, while selected conflict, know-your-customer and anti-money-laundering checks fell from hours to minutes. Codex assisted with audit reports covering 300 entities and file-processing work, with people reviewing and approving the results. These are examples of selected workflows, not evidence that all legal work has been automated.
