Willkie Farr Goes Firmwide on ChatGPT Enterprise; Extends AI into Willkie Works Innovation Platform with Codex

LinkedIn commentary (August 1, reporting Willkie's announcement) confirmed that Willkie Farr & Gallagher has gone firmwide on ChatGPT Enterprise — OpenAI's first major Am Law 100 law firm deal that can be publicly confirmed since OpenAI stood up a legal vertical. Willkie is extending the deployment into Codex inside Willkie Works, its own AI and innovation organisation. The same week: Debevoise & Plimpton launched a public AI@Debevoise page (August 3) explaining how the firm uses AI across practice and operations, the governance framework that guides its use, and the principles underpinning deployment — quality, confidentiality, and responsible deployment. For law firm innovation leaders tracking the transparency trajectory: the Debevoise disclosure page is the most explicit client-facing AI transparency initiative launched by an Am Law 100 firm this week. The Willkie ChatGPT Enterprise + Codex deployment is the most comprehensive technology-stack AI rollout at the firm-organisation infrastructure level. Both are consistent with the client expectation finding from the week's research: 58% of GCs say their firms rarely or never bring up AI with them.
