You need a test dataset, but making one from scratch is painful. Your best examples are already in your production traces — the edge cases your users actually hit, the queries that tripped up your model, the responses that were perfect. Arize AX lets you turn those into a dataset directly, no pipeline needed.

​
How to do it

Individual: Open a span → click Add to → Dataset → choose or create a dataset. Bulk: Select multiple spans in the traces table → Add to → Dataset. Using Alyx: “Create a dataset from the filtered spans” or “Add these error traces to my test dataset” [screenshot: add to dataset dialog]

What gets saved

Each span’s input, output, and metadata are added as a dataset example — everything you need to replay the scenario in an experiment.
