Image models

When creating AI generated images in your gamma, you can specify which model to use.

Quick reference

  • Set imageOptions.source to aiGenerated when using any of the model strings below.

  • If imageOptions.model is omitted, Gamma selects a model automatically.

  • Higher-tier, HD, and video models usually take longer to complete, so longer polling windows may be helpful.

  • All models below are available to API users (Pro plan and above). Models are grouped by credit cost.

  • See Access and Pricing for plan and credit details.
