Batch generation

3 min readUpdated

Apply one prompt to multiple images in independent tasks.

Use Per image for consistent edits across multiple images, including background replacement, cutouts and style changes.

Execution model

Without prompt slots, N input images create N independent tasks, each requesting one output image. Enter the prompt once; each task reuses it with the selected model and settings.

Each task receives only its current input image, with no other references or task results. Tasks may run concurrently or queue; completion order can vary.

Images A, B and C pair with the same prompt in three independent tasks, each producing one result without sharing images

Submission checks

  1. Output count: check the settings chip at the bottom, showing 3 images here.
  2. Total cost: check the credits on the send button, showing 240 for the entire batch here. Confirm both before sending.

Prompt guidelines

Describe the edit for “the current image”. Avoid references to other images or previous results.

Product image on white
Preserve the shape, colors, materials and markings of the product in the current image. Replace the background with pure white. Center the complete product and add a natural contact shadow. Do not add text or other objects.

Limits and retries

  • Task count: input images × prompt combinations. The ordinary Count setting does not multiply this total. With slots, 3 images × 2 backgrounds create 6 tasks.
  • Limits: up to 50 output images per batch; each reference must be no larger than 50 MB.
  • Cost: for the same model and settings, batch estimate = per-image estimate × total output count.
  • Retries: review the failure reason and retry the affected task. Completed results are retained.
