Harvey is building legal agents and workflows using OpenAI's o1 reasoning model. The model outperforms prior foundation models on Harvey's BigLaw Bench and expert preference evaluations, though it still falls short of Harvey's domain-specialized assistant models. Harvey's step-change review highlights o1's capabilities in reasoning, planning, and collaboration as key enablers for next-generation professional service agents.

> Open AI o1's performance on evaluations of agentic capabilities including reasoning, planning, and collaboration is—by far—the thing we are most excited about.
