Astra for Law

A version of GPT-6 Astra set up for legal research, available first to selected law firms through Trusted Access in ChatGPT and Codex.

Pairs GPT-6 Astra with instructions written for legal analysis and writing, plus a Legal Search Index that searches U.S. case law, statutes, regulations, court rules, and administrative decisions across more than 230 million URLs, with new sources added daily
The case law comes from a collaboration with the Free Law Project, the nonprofit behind CourtListener, covering more than 99.9% of published U.S. precedential case law
Launches with 26 partner plugins from Thomson Reuters, Intapp, Harvey, Legora, DeepJudge, and iManage
Selected law firms get it through Trusted Access in ChatGPT and Codex first. API access comes later, and Harvey and Legora will build on it

Legal research that has to cite real sources: checking case law, statutes, and regulations before an argument gets written.

You need answers grounded in primary legal sources rather than a general model's recollection of them.
