Initially created as a single-user proof of concept using Codex by partner John Savva, the tool now integrates ChatGPT Enterprise, curated firm precedents, and negotiating playbooks into a multi-user workflow.\n\nAgreement Analyzer uses specialized agents that perform review cycles in parallel to analyze contract terms against client priorities and market practice. The process uses an adversarial setup where agents challenge each other's conclusions, distinguishing verified findings from unverified issues. The system outputs a memorandum and suggested tracked changes for lawyers to review, adapt, or reject.\n\nSullivan & Cromwell partner John Savva noted that improvements in AI analytical capabilities have enabled automation for complex tasks beyond basic administrative work. He highlighted advances in reasoning capabilities with GPT-6 Astra as a key factor in improving the quality of legal research and writing workflows.","keyPoints":["Sullivan & Cromwell created Agreement Analyzer in collaboration with OpenAI to automate draft agreement reviews.","The tool uses ChatGPT Enterprise and multi-agent adversarial processing to evaluate contract terms against firm playbooks.","Partner John Savva noted that reasoning capabilities in models like GPT-6 Astra advance complex legal analysis."],"whyItMatters":"The collaboration highlights how professional service firms are moving beyond basic administrative AI uses toward multi-agent reasoning systems that assist with complex core tasks like legal contract analysis.","category":{"slug":"enterprise","name":"Enterprise & Industry","url":"https://digestai.news/category/enterprise"},"entities":{"companies":["Sullivan & Cromwell","OpenAI"],"models":["Codex","ChatGPT Enterprise","GPT-6 Astra"],"people":["John Savva"]},"firstPublishedAt":"2026-10-15T00:00:00Z","updatedAt":"2026-10-15T00:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"OpenAI","title":"Sullivan & Cromwell brings legal expertise into agreement review","url":"https://openai.com/index/sullivan-cromwell","publishedAt":"2026-10-15T00:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Sullivan & Cromwell builds legal tool Agreement Analyzer with OpenAI\", 15 October 2026, https://digestai.news/story/sullivan-cromwell-builds-legal-tool-agreement-analyzer-with-openai","publisher":"Digest AI","title":"Sullivan & Cromwell builds legal tool Agreement Analyzer with OpenAI","datePublished":"2026-10-15T00:00:00Z","url":"https://digestai.news/story/sullivan-cromwell-builds-legal-tool-agreement-analyzer-with-openai"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
