𝗝𝗼𝗵𝗻 𝗦𝗮𝘃𝘃𝗮, Partner, Sullivan & Cromwell:

“We were grateful to preview early versions of Astra for Law, which were built with legal use-cases in mind. Across both litigation and transactional matters, the models demonstrated impressive research depth and sensitivity to authority. Even at this early stage, they felt like a significant step toward legal-focused AI that is carefully grounded in research that is both current and comprehensive.”

𝗠𝗶𝗰𝗵𝗮𝗲𝗹 𝗥𝘂𝗯𝗶𝗻, Chair of Latham’s AI Strategy Committee:

“As AI becomes more capable, so too does the ability to deploy it in environments that demand rigorous governance, oversight, and accountability. This collaboration builds on Latham’s broader investments in AI development, governance, and infrastructure across the firm, which underpin our enterprise-wide strategy for responsible AI.”

𝗗𝗮𝘃𝗲 𝗣𝗲𝗶𝗻𝘀𝗶𝗽𝗽, partner and co-chair of Cooley’s global capital markets group:

“Our collaboration with OpenAI has allowed us to rethink how this work gets done – moving lawyers and management teams more quickly through intensive preparation and into questions that require judgment, market experience and strategic thinking.”

𝗝𝗼𝗲𝗹 𝗛𝗿𝗼𝗻, Chief Technology Officer, Thomson Reuters:

“As AI becomes more open and interoperable, the value is not in connectivity alone. Legal professionals need more than access to information. They need trusted intelligence, relevant enterprise and matter context, purpose built legal capabilities, and the governance required for high stakes work. That is what Thomson Reuters delivers through HighQ and CoCounsel Legal. CoCounsel remains the trusted professional AI system designed to help complete that work. Our work with OpenAI helps make these capabilities available in the environments customers choose, while preserving the accuracy, confidentiality, and accountability they depend on.”

𝗪𝗮𝗰𝗵𝘁𝗲𝗹𝗹, 𝗟𝗶𝗽𝘁𝗼𝗻, 𝗥𝗼𝘀𝗲𝗻 & 𝗞𝗮𝘁𝘇:

“We’ve appreciated the technical depth and willingness to listen that OpenAI’s forward deployed engineering team has brought to our conversations about AI's role in supporting legal work, and are excited about the possibilities of AI to shape the next era of legal practice.”
