## 正文

OpenAI has introduced Astra for Law, a version of its GPT-6 Astra model built for legal work. It pairs the model with a legal search index and instructions for analysis and writing.

The index searches US case law, statutes, and regulations across more than 230 million URLs. OpenAI draws on data from the Free Law Project, which says it covers over 99.9 percent of published US precedents. In a test OpenAI ran itself using Vals AI's Legal Research Bench, Astra for Law passed 54 percent of the 200 questions, compared to 38.7 percent for GPT-6 Astra with plain web search.

OpenAI says API customers like Harvey and Legora can build on it. Law firms get a Trusted Access program with privacy controls like zero data retention. The company is also launching 26 plugins for tools such as Relativity and Clio. OpenAI isn't alone here. Anthropic is also expanding its presence in the market for legal work.
