Harvey, the legal AI startup known for its tailored solutions for law firms, announced that it has integrated foundation models from Anthropic and Google into its platform, shifting from its previous exclusive use of OpenAI models. The goal is to provide users with improved results and greater control over their AI tools.
Key Points:
- Harvey now incorporates Anthropic’s Claude and Google’s Gemini models alongside OpenAI.
- The multi-model approach enhances performance across various legal tasks.
- Users can select specific models or allow Harvey to auto-route tasks for optimal results.
Harvey’s decision to diversify its AI model offerings comes in response to the evolving landscape of foundation models. According to the company’s blog post, the integration of Anthropic’s Claude and Google’s Gemini models allows Harvey to auto-route tasks to the most suitable model, enhancing the quality of outputs for legal professionals. This multi-model strategy not only improves default responses but also offers users the option to select specific models tailored to their needs.
The company emphasizes that different models exhibit varying strengths across legal tasks. For instance, Gemini 2.5 Pro excels in legal drafting but may underperform in trial preparation due to challenges in reasoning about complex evidentiary rules. By leveraging multiple models, Harvey aims to capitalize on each model’s strengths, ensuring optimal performance across diverse legal workflows.
To support this initiative, Harvey is enhancing its evaluation processes. The company plans to maintain a public leaderboard for its proprietary benchmark, BigLaw Bench, providing transparency on model performance. Additionally, expert evaluations will offer nuanced insights into model outputs, considering factors like tone, style, and structure, which are increasingly influencing user preferences.
This expansion aligns with Harvey’s broader strategy to remain at the forefront of legal AI innovation. With the legal industry witnessing a surge in AI adoption, Harvey’s move to a multi-model platform positions it to better serve its clientele, which includes eight of the top ten highest-grossing law firms in the nation. As the company continues to evolve, its commitment to delivering tailored, high-quality AI solutions for legal professionals remains steadfast.
