OpenAI launches Astra for Law: GPT-6 legal platform escalates industry race

OpenAI has officially launched Astra for Law, a specialized, legal-focused AI platform built on its GPT-6 Astra model.

The Sam Altman’s AI firm said its new product combines its Astra model with an index of US case law, statutes, regulations and other legal materials, along with specialized instructions for legal analysis and writing.

This move marks a major escalation in the competitive race among major tech developers (including Google and Anthropic) to capture lucrative legal industry users and corporate legal departments.

As reported, Google last month expanded its Gemini Enterprise offerings for legal professionals, and Anthropic since January has released tools for lawyers using its Claude AI assistant.

Massive Legal Search Index:

The platform integrates a search index covering over 230 million URLs of U.S. case law, statutes, regulations, court rules, and administrative decisions, partnering with the Free Law Project (CourtListener).

Measurable Performance Boosts:

According to OpenAI’s testing on legal benchmarks, Astra for Law achieved 54.0% overall correctness on complex U.S. legal research questions—a major improvement over general web search configurations.

Ecosystem Integrations & Plugins:

The platform launches with 26 new ecosystem plugins connecting ChatGPT to industry-standard legal tech tools like Relativity, Clio, Intapp, iManage, and Thomson Reuters.

Legal tech startups and API customers like Harvey and Legora are also building directly on top of the foundation.

Enterprise Security & Privacy Controls:

To address strict attorney-client confidentiality rules, OpenAI is providing a Trusted Access Program featuring Zero Data Retention (ZDR) on its API, while excluding ChatGPT Enterprise user data from human review by default.

Major Am Law firms including Sullivan & Cromwell, Ropes & Gray, Cooley, Latham & Watkins, and Wachtell Lipton, participated in early testing and development.

By providing a native foundation layer rather than just an end-user chatbot, OpenAI is positioning itself to power both individual attorneys and the specialized legal AI vendors they already rely on.
