Gilbert + Tobin Rolls Out ChatGPT Enterprise and Codex, Reports 87% Active Use
Nov 12, 2026
Australian law firm Gilbert + Tobin says 87% of enabled ChatGPT users are active after a firmwide rollout of ChatGPT Enterprise, ChatGPT Work and Codex.
Australian law firm Gilbert + Tobin has rolled out OpenAI's ChatGPT Enterprise, ChatGPT Work and Codex across the firm, and 87% of enabled ChatGPT users are active, BigGo Finance reports from an OpenAI customer story. That is more than double the adoption the firm usually sees for other software.
The firm started by letting staff try consumer ChatGPT under a rule that no client or confidential information could be entered. It then moved to ChatGPT Enterprise with Australian data residency, role-based access and admin controls before widening access to operations, marketing, recruitment, finance and parts of the legal practice. Codex now runs multistep tasks under human review.
Chief executive Sam Nickless said lawyers still define tasks, check outputs and remain accountable for final work. The firm set no usage quotas and expected executives to use the tools themselves. For the confidential annual review of its 120 partners, Nickless said ChatGPT Work updated files, generated PDFs and bundled the material in minutes, at a cost of about $62.
