Legal AI platform Harvey is using GPT-6 Astra to help law firms and in-house legal teams deploy AI across complex workflows, ranging from litigation to mergers. By leveraging the model's enhanced context processing, Harvey can produce more structured and context-aware legal documents from vast amounts of information, such as court records, case law research, and firm documents.
Harvey integrates GPT-6 Astra to improve legal document drafting and context awareness
Harvey reports substantial improvements in document formatting and context awareness compared to other models when using GPT-6 Astra. This allows customers to generate more complete documents that accurately reflect their underlying source materials.
The platform also features a "memory panel" that integrates individual lawyer preferences directly into the drafting workflow. Users can encode specific requirements—such as using numbered lists, prioritizing EDGAR as a source, or color-coding issues by priority—which appear alongside source materials to guide the output. With the increased context capabilities of GPT-6 Astra, Harvey aims to enable lawyers to focus more of their time on legal strategy rather than manual drafting.
