POST
Regenerate 4 images from the source task’s prompt (equivalent to the 🔄 button). The whole grid is re-rolled, so no index is needed.

Parameters

Auto matching

The service finds a reroll-related button from the source task buttons that contains ::reroll::, or matches reroll emoji.

Request example

Error responses

Response

On success you receive a new local task_id. Poll GET /v1/tasks/{task_id}; on SUCCESS you get a fresh 2x2 grid with the same prompt. The source task’s prompt / version / niji / structured fields are inherited automatically (the seed may differ, so results differ). To price by speed, configure midjourney@reroll-fast / midjourney@reroll-turbo.

Notes

  • You can only reroll an imagine grid or a grid produced by reroll itself; you cannot reroll a task that already went through upscale / variation / pan, etc.
  • The parent task must be in SUCCESS state.
