What's New

We’ve added GPT-5.6 Sol to the model selector in Harvey. GPT-5.6 Sol delivered strong results across document review and analysis, drafting, and case management.

Learn more about our evaluation of this model in our blog post for GPT-5.6 Sol.

Why It Matters

GPT-5.6 Sol expands the range of models available in Harvey, giving advanced users more flexibility.

For most workflows, Auto mode continues to select the right model for you, but model selection is available if you want more direct control.

This update ensures Harvey adapts to different types of legal work without changing how you normally use it.

How to Use

Open Model Selector in Assistant, Vault, or Workflow Builder to select GPT-5.6 Sol from the list of models. Admins can manage access through Access Control & Permission Management.
