OpenAI Brings GPT-6 Astra to Legal Industry, Targeting Major Law Firms With AI-Powered Research Tools

OpenAI has launched Astra for Law, a specialized version of its GPT-6 Astra model designed specifically for legal work, achieving significantly higher accuracy on legal research tasks than the general-purpose model. The platform combines the latest AI model with a curated legal search index spanning over 230 million URLs of U.S. case law, statutes, regulations, court rules, and administrative decisions. On a benchmark of 200 legal research questions, Astra for Law achieved 54% overall correctness compared to 38.7% for GPT-6 Astra using web search alone—a 40% relative improvement—and retrieved up to 54% more relevant passages from correct court opinions.
