The initial release is going to selected firms through Trusted Access. It will work in ChatGPT and Codex, with API access due to follow.

What Astra for Law Adds to ChatGPT
Astra for Law pairs GPT-6 Astra with instructions for legal analysis and writing. It also includes settings intended for thorough work and context designed to support legal expertise and judgement.
The model is part of a wider legal configuration maintained by OpenAI. That means product builders can work on their applications and workflows without maintaining that configuration themselves.
This follows the arrival of GPT-6 Astra across several products, covered in our ChatGPT roundup tracking GPT-6 Astra across five platforms. Astra for Law applies that model to a defined professional workflow, with its own instructions, settings, search collection and plugin catalogue.
| Component | What is included | Purpose |
|---|---|---|
| Model | GPT-6 Astra | Legal analysis and writing |
| Configuration | Legal instructions and thorough-work settings | Maintained legal working context |
| Search | U.S. Legal Search Index | Finds authorities and supporting passages |
| Partner plugins | 26 plugins | Connects specialist tools and knowledge |
| Community plugins | 47 plugins | Gives firms adaptable legal skills |
The offering is designed to support lawyers’ existing judgement. Search results include authorities and passages that lawyers can examine themselves, rather than removing that review step.
Legal Search Covers More Than 230 Million URLs
The new Legal Search Index searches U.S. case law, statutes, regulations, court rules and administrative decisions. Its collection covers more than 230 million URLs, and new sources are added daily.
A lawyer can begin with the facts of a matter, find relevant authorities and inspect the supporting passages returned by the search. The source material remains available for examination as part of that process.
- 1
Start with the matter
provide the relevant facts for legal analysis
- 2
Search the index
identify related U.S. authorities across the covered source types
- 3
Inspect the passages
examine the supporting text returned with the authorities
- 4
Continue the work
use the legal writing instructions and configured settings
The index is specifically described as covering U.S. legal material. The announced categories span primary legal authorities and procedural sources: cases, legislation, regulations, rules of court and administrative decisions.
Plugins Connect Legal Tools and Firm-Built Skills
Astra for Law launches with 26 partner-built plugins. Named partners include Thomson Reuters, Harvey, Legora and iManage. These plugins connect specialist tools and knowledge to legal work in ChatGPT.
Another 47 community plugins come from lawyers and legal engineers. Firms can adapt and extend those community-built skills for their own work.
The two plugin groups have different origins. Partner plugins connect established specialist products and knowledge, while community plugins provide skills created within the legal and legal engineering community. Both sit alongside the maintained model configuration and Legal Search Index.
Trusted Access Comes First
Selected firms will receive Astra for Law first through Trusted Access in ChatGPT and Codex. API access is coming soon, which will give legal technology builders another route for putting the maintained configuration into their own products and workflows.
OpenAI plans to develop the offering alongside participating lawyers and legal technology partners. The initial access model therefore puts the product into selected firms before the API release.
