The company's newest artificial intelligence configuration for attorneys combines GPT-6 Astra with specialized settings to automate legal analysis and drafting. Released on September 17, Astra for Law uses a search index covering more than 230 million URLs of U.S. case law, regulations, and statutes. Internal evaluations indicate this specialized layer increased legal research correctness from 38.7% to 54%.
Astra for Law scored 90.0% on a weighted rubric using the Vals Legal Research Bench, compared to 84.1% for standard GPT-6 Astra with web search. The platform includes 26 partner-built and 47 community plugins for ChatGPT and is available to selected firms through Trusted Access in ChatGPT and Codex. API access follows for developers and partners, including the legal tech firm Spellbook.
