v0.2 of Gamma's API offerings will be deprecated on Jan 16, 2026.
Please move to v1.0 of Gamma's API endpoints before this date to avoid disruption.

When creating AI generated images 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.
Conversely, if you're not sure which image model you'd like to use, you can leave the imageOptions.model parameter blank and Gamma will select a model for you.
