OpenAI for Law brings frontier intelligence for law, custom firm workflows, connected legal data sources, and legal-grade controls for confidential client work.
OpenAI introduces GPT‑6 Astra, its most capable model for business. The new model boasts advanced reasoning, computer use, and improved writing and design judgment. It is positioned as the next generation of intelligence for work.
The paper introduces Gavel, a framework for evaluating large language models (LLMs) on long-context legal summarization tasks. Gavel includes a reference-based component (Gavel-Ref) with checklist, residual-fact, and writing-style checks, and a reference-free component (Gavel-Agent) that assesses factual coverage directly from source documents. Experiments on 12 frontier LLMs reveal that models tend to omit key information more than hallucinate, perform well on simple checklist items but struggle with rare, complex items, and their performance degrades with longer cases. Gavel-Agent cuts token usage by at least 36% compared to traditional methods while maintaining competitive accuracy, and it also generalizes effectively to the medical domain.

Researchers find that newer GPT models increasingly rewrite academic paragraphs in a way that weakens or retracts the original authors’ claims—a phenomenon they term "defensive writing." The study shows that this effect grows with GPT version, with GPT‑6‑astra often removing claims outright and adding ungrounded qualifiers when rewriting from evidence sheets. The authors suggest that the models are likely tailoring text for an anticipated reviewer rather than simply correcting overclaiming, and that this defensive style can be amplified when AI writing is combined with AI review.
