Human Review is now configured at the project level for better organization and control. If you previously configured workspace-level human reviews, they will continue to work but are soon deprecated.
Unified Annotations System: Human Reviews are part of the Annotations system. Use the Annotations API to programmatically apply human reviews to traces, or use Annotation Queues to manage human review workflows in the UI.

​
What is a Human Review

Human Reviews let you create custom fields for structured annotations on model generations. Once created, a Human Review is available on all traces and spans within the project — no additional configuration or filtering required.

​
Creating a Human Review

To create a Human Review, head to Project Settings > Human Review and press the + button.
There are 3 human review types available:
  • Categorical: Create button options with your own labels, such as good/bad or saved/deleted.
  • Range: Set up a custom scoring slider (for example, a scale from 0 to 100).
  • Open field: Allow users to enter free-form feedback, perfect for more detailed comments.

​
Using Human Review
