Linking a dataset to the Playground connects your prompt to a structured collection of test cases, enabling scalable testing without manual copy-pasting. Each row in the dataset represents a different set of variable values — select a row and run to test your prompt with that specific combination.

​
Quick start

1

Create a prompt with variables

Set up your prompt in the Editor with at least one {{variable}} placeholder.A prompt with variables in the Editor

Link the dataset

3

Navigate and run

Browse through dataset rows — selecting a row populates the Variable Editor with that row’s values. Click Run to execute the prompt with the selected row’s inputs.Navigating dataset rows in the Playground

Key features

  • Full bi-directional sync — New variables in the Editor automatically create columns in the linked dataset, and vice versa. Same for rows and cells.
  • Column mapping — Columns map to variables by name. Extra columns are ignored; missing columns fall back to Variable Editor values.
  • Dynamic columns — Columns configured as API or Prompt sources are executed at runtime with fresh data.
