## Summary

OpenAI announced Astra for Law on September 17, 2026. The offering wraps the GPT‑6 Astra model with a legal search index that spans more than 230 million URLs, drawing case law from the Free Law Project’s CourtListener database. In Vals AI’s Legal Research Bench, Astra for Law answered 200 questions correctly 54 % of the time, compared with 38.7 % for GPT‑6 Astra alone, and retrieved up to 54 % more relevant passages. Access is limited to selected firms through a Trusted Access program in ChatGPT and Codex, appears in the model picker as GPT‑6 Astra Law, and will later be offered via an API (gpt‑6-astra-law). Harvey Technologies Inc. and Legora AB are named as early API customers, and 26 partner‑built plugins plus nine community plugins were released, linking tools such as Relativity, Clio, iManage, DeepJudge and Thomson Reuters HighQ.

Business Insider adds that OpenAI is targeting the AmLaw 200 and that the model’s responses are about twice as long as typical Astra outputs, quoting legal product lead Jason Boehmig and technical staffer Sherwin Wu. SiliconANGLE includes a comment from Thomson Reuters CTO Joel Hron about the need for trusted intelligence beyond connectivity, while Unite.ai notes that GPT‑6 Astra meets OpenAI’s Critical cybersecurity threshold and is rolling out on Azure and AWS Bedrock.
