OpenAI Announces Harvey Powered by GPT-6 Astra for Enhanced Legal Drafting

TL;DR

OpenAI announced that its Harvey platform now runs on GPT‑6 Astra, delivering richer legal context, better‑structured outputs, and customizable drafting preferences, which enables law firms to produce more complete and accurately formatted documents.

Overview of the Harvey Upgrade

Harvey is a secure AI solution for law firms and in‑house legal teams that automates complex workflows such as litigation and mergers. The integration of GPT‑6 Astra expands Harvey’s ability to ingest larger volumes of legal context—including court filings, firm documents, and case‑law research—resulting in more comprehensive drafts.

“We can give more context to the model and produce better and better structured outputs.” —Gabe Pereyra, Cofounder and President, Harvey

Improved Document Completeness and Formatting

Harvey leverages GPT‑6 Astra’s enhanced context window to analyze and synthesize disparate sources of legal information. Compared with prior models, the platform now generates drafts with noticeably superior formatting and a higher degree of contextual awareness. Users report that the resulting documents more accurately reflect the underlying material, reducing the need for manual re‑formatting.

Preference‑Driven Drafting via the Memory Panel

Harvey introduces a “memory panel” that lets individual lawyers encode drafting preferences directly into the workflow. Preferences can include:

  • Using numbered lists for clarity
  • Prioritizing specific data sources such as EDGAR filings
  • Applying color‑coding to highlight issue priority

These preferences are displayed alongside source excerpts and the draft memorandum, giving lawyers explicit control over the output. Because GPT‑6 Astra can process more context, the system can honor these preferences while still delivering high‑quality legal text, allowing lawyers to focus on strategic analysis rather than document mechanics.

Implications for Legal Practice

The combination of deeper context ingestion and customizable drafting preferences positions Harvey as a more powerful tool for legal professionals. By automating formatting and integrating user‑defined styles, the platform reduces repetitive editing work and accelerates the production of legally sound documents. This upgrade may set a new baseline for AI‑assisted legal drafting, prompting broader adoption across the industry.

Conclusion

Harvey’s upgrade to GPT‑6 Astra demonstrates how larger context windows and preference‑aware interfaces can materially improve AI‑generated legal drafts. The announcement underscores OpenAI’s focus on domain‑specific AI solutions that enhance productivity while preserving the strategic role of human lawyers.
