According to a recent LinkedIn post from Harvey, the company has been testing Google and DeepMind’s new Gemini 3.1 Pro model during its public preview phase. The post indicates that Harvey’s AI and Applied Legal Research teams evaluated the model, with particular attention to its long-context handling, multimodal reasoning, and performance in ideation and writing tasks.

The post suggests that Gemini 3.1 Pro will be integrated into Harvey’s platform once the model reaches General Availability. For investors, prospective access to a stronger underlying foundation model could enhance Harvey’s product capabilities in complex legal workflows, potentially improving customer value, competitive differentiation versus other AI legal tools, and long-term pricing power.
The emphasis on long-context and multimodal reasoning may be especially relevant for large law firms and enterprise clients that work with extensive documentation and varied data types. If Gemini 3.1 Pro materially improves drafting quality and research support within Harvey, it could support higher user adoption, increase retention among existing clients, and strengthen Harvey’s position within the AI-assisted legal services market.
