When creating AI-generated images or videos in your gamma, you can specify which model to use. To do so:

In the imageOptions.source parameter, use aiGenerated as the value.
In the imageOptions.model parameter, use one of the strings below.
If you're not sure which model to use, leave the imageOptions.model parameter blank and Gamma will select a model for you.

The Min Plan column indicates the minimum subscription plan required to use each model.
