Model Updates

Harvey has launched Multi-Model Support, enabling workspace admins to roll out Anthropic’s Claude and Google’s Gemini models directly via self-serve permissions. These models join our existing OpenAI-powered systems, offering teams greater flexibility and performance across legal tasks.

With multiple foundation models now available in Harvey, users benefit from:

  • Better default results, as Harvey routes tasks to the most capable systems
  • More control, through admin-managed model access and optional Model Selector

What’s new:

  • Claude + Gemini models: Now available to be rolled out by workspace admins
  • Model Selector (opt-in): Enables users to switch models in Assistant, Vault, and Workflow Builder
  • Expanded support: OpenAI models remain fully supported

Secure and compliant:
Claude and Gemini are integrated via AWS Bedrock and Google Vertex AI, with the same privacy and security guarantees that underpin all of Harvey’s systems.

Why it matters:
This launch marks the first step in Harvey’s shift toward a more adaptive and extensible AI platform for professional & legal work. Multi-model support allows us to:

  • Dynamically match users with the right model for the right task
  • Customize workflows based on specific needs
  • Accelerate evaluation and integration of future models offering unique advantages
