View traces

To view a trace, select a log from your project's Logs page or from an experiment on the Experiments page. The trace opens in a panel on the right side of your screen.

This panel shows a tree of all of the spans that make up the trace. Use the button in the top left of the panel to expand it to full screen. Select a span to see its metrics, input, output, expected, metadata, and activity.

Search, filter, and bulk select spans

Select Find in the top right corner of the trace panel or page to find a specific span in a trace. You can then select the filter icon to filter further by span type or span field. Once you've found the spans you're looking for, you can use the checkboxes to select or bulk select them and add them to a new or existing dataset in your project.

Diff traces

Use the Diff toggle on the top right of an experiment page to compare traces across experiments. In the Comparisons panel on the left, use the drop down menu to select which experiments to compare. Each row in the trace view will show a list of the outputs from the selected experiments for that trace. You can select multiple experiments to compare at once.

Re-run a prompt

Select Run to edit and re-run any chat completion span inside a trace. In the Run prompt window, make any changes you'd like to the prompt and select Test to see the output. You can also give this prompt a name and select Save as custom prompt to save it to your project's prompt library.
