OpenAI has launched Astra for Law, a new foundation combining the GPT-6 Astra model with specialized settings, tools, and context tailored for professional legal work. This configuration includes a powerful legal search index covering over 230 million URLs and 99.9% of U.S. precedential case law to assist in finding relevant authorities.
- Astra for Law achieved a 54.0% correctness rate on Vals AI’s Legal Research Bench, representing a 40% relative improvement over GPT-6 Astra using web search alone.
- The system retrieves up to 54% more relevant passages from correct court opinions and finds 24% more reference cases on case-law-focused questions.
- OpenAI is offering 26 new ecosystem plugins connecting ChatGPT to specialist tools like Relativity, Clio, and Thomson Reuters HighQ.
- Eligible law firms gain access via Trusted Access in ChatGPT and Codex, featuring Zero Data Retention (ZDR) and exclusion from human review by default.
The launch provides law firms with a stronger research foundation for advising on deals and disputes, while allowing them to build custom applications using their own precedents and methods.
