Introducing Review Mode

A new way for domain experts to annotate traces with human feedback.

With Review Mode, you can:

• Tag traces with annotations from your Human Evaluators definitions
• Apply your custom criteria right in the UI
• Add comments when something interesting pops up

This should make life easier when you’re combing through traces and need to mark things for later. Perfect for when the whole team needs to analyze outputs together.

Check it out in Experiments and Data Store - look for the “Review Mode” button.
