OpenAI launches Astra for Law with five firms in its initial program
Inside Practice · SEPTEMBER 23, 2026 · 1 MIN READ
On September 17, Reuters reported that OpenAI launched Astra for Law, combining GPT-6 Astra with an index of US cases, statutes and regulations plus integrations with legal software providers. OpenAI said Sullivan & Cromwell, Ropes & Gray, Cooley, Latham & Watkins and Wachtell Lipton participated in testing or development and that selected firms would receive initial access with protections for confidential work. The launch makes model-provider governance part of legal-stack architecture because firms must assess not only an application but also the legal corpus, integrations and downstream builders that use the model. Buyers should test source coverage, permissions and contractual confidentiality at every layer rather than infer them from the platform’s legal branding.
