# Compare Datasets

Compare results from multiple datasets or runs side by side. Use diff view to spot performance differences across models and dataset versions easily.

The Compare Datasets feature allows you to juxtapose results from different datasets and compare the results side by side. This helps you identify patterns, strengths, and weaknesses across multiple datasets.

To merge two datasets, follow these steps:

1. Inside the Evaluations tab, click on the "Select to compare" button to select multiple datasets for comparison.
