OpenAI Launches Astra for Law, a GPT-6 Astra Tuned for Legal Work
OpenAI is opening a second front in professional AI with a tuned model, a case-law index, and a pilot that runs through law firms rather than the general ChatGPT audience.
Reporting from 1 source: GIGAZINE.
OpenAI announced Astra for Law, a version of its frontier model GPT-6 Astra fine-tuned for legal tasks and paired with specialized settings, tools, and context. It includes built-in prompts for legal analysis and document drafting, administrative features for confidential client work, and a legal search index covering more than 99.9% of U.S. case law. It goes first to selected law firms through Trusted Access for ChatGPT and Codex, with API support planned soon.
The legal search index behind Astra for Law holds data from more than 230 million URLs, according to OpenAI, and the company says sources are added daily. Users can search case law, statutes, regulations, court rules, and administrative decisions.
Plugins connect ChatGPT to tools law firms already use, including Relativity and Clio, so firms can customize the model around existing workflows. On benchmarks measuring legal capabilities, Astra for Law scored higher than GPT-6 Astra with web search on Weighted rubric score and All-pass rate.
OpenAI framed the release as a long-term investment in the legal field, with continued updates based on evaluation and feedback from lawyers and legal technology partners.
