What is changing?
OpenAI described Agreement Analyzer, developed with Sullivan & Cromwell, on October 15. The tool compares corresponding provisions in a draft agreement against selected precedents and tracks how clauses interact. The initial single-user proof of concept was built with Codex, then expanded for parallel processing and use by multiple lawyers.
The system brings together the firm’s selected precedents, negotiation playbooks, market-practice information, and ChatGPT Enterprise in one workflow. It runs several review cycles from different perspectives to identify potential issues, then produces a memorandum and tracked changes that a lawyer can accept, revise, or reject.
According to OpenAI’s account, some agents form conclusions while other agents challenge them. The output separates supported findings, dismissed findings, and issues retained with qualifications because they remain unverified. Lawyers remain responsible for final legal judgments and changes.
