OpenAI introduced Astra for Law on Thursday, a new artificial intelligence foundation built on the GPT-6 Astra model. Designed specifically for law firms and legal technology companies, the tool is tailored for complex legal research and workflows.
What Happened
On Thursday, OpenAI announced the launch of Astra for Law, built upon its GPT-6 Astra model. The new offering combines OpenAI's latest model with specialized tools and settings tailored directly for legal work. To ensure comprehensive coverage of legal materials, the system incorporates a legal search index containing over 230 million URLs.
Additionally, OpenAI partnered with the Free Law Project to integrate the CourtListener case-law collection. This collection covers more than 99.9% of published U.S. precedential case law. Astra for Law also integrates with API customers like Harvey and Legora, enabling them to build upon the technology and embed it into their own products and workflows.
