Astra for Law

Launched 17 September in the United States, pairing GPT-6 Astra with a dedicated legal search index covering US case law, statutes, regulations, court rules and administrative decisions across more than 230 million sources, built with the Free Law Project and CourtListener and updated daily, plus legal-specific instructions and tooling. Reported gains are 40% more accurate research answers, 24% more reference cases found and 54% more relevant passages retrieved against Astra using plain web search. Access is through a Trusted Access programme in ChatGPT and Codex with the API to follow, with Latham & Watkins, Ropes & Gray, Cooley and Sullivan & Cromwell named as early adopters and 26 partner plugins. openai.com blocks automated fetches, so this rests on secondary coverage.
