Invitation-only for selected law firms and covering US law only, so most UK lawyers can't use it, and pricing is unpublished.

Kenning's take

What it does

Astra for Law is a version of OpenAI's GPT-6 Astra configured for legal research and drafting, not a separate model. It adds a search index of US case law, statutes, regulations and court rules. Selected law firms can use it in ChatGPT and Codex through a Trusted Access programme, and an API version is planned.

• Legal search index of more than 230 million US legal sources
• Case law from the Free Law Project's CourtListener
• Appears as GPT-6 Astra Law in the ChatGPT and Codex model picker
• Planned API model named gpt-6-astra-law
• Zero data retention on the API for eligible firms

Who it suits. Law firms and legal software companies doing US legal research and drafting.
