Models are constantly updating and new ones are launching all the time, which makes it important to test your prompts across a wide variety of models.
PromptHub makes this extremely easy, taking just a few clicks:
On the playground page click the "batch" icon in the "Run Test" button
Select the number of times you want the prompt to run
For each test run, update the model by clicking on it and selecting any model
Click "Run as Batch" and you'll then be able to judge outputs from different models side-by-side
Tips
API Setup: Ensure you have API keys set up for all the model providers that you are testing across
Experiment: Feel free to adjust parameters and variables to see how changes affect the output.
