Use this endpoint to preview the currently selected region before you submit the final multimodal edit task.

​
Why preview matters

  • It lets you verify that the selection points cover the intended object or area
  • It helps catch bad masks before you spend a generation call
  • It is the safest checkpoint between selection editing and final task creation

​
Workflow role

Initialize the session

3

Preview before generating
