Which mode should I choose?

Use Batch if you upload more than a few images at a time. It is cheaper and lets you set categories, AI labels, and content type for the whole series in one place.

Use Turbo if:

• you have a single image to process
• you want to regenerate a Batch result you did not like
• you need metadata immediately.

Most workflows are: Batch for the bulk of uploads, Turbo for one-offs and re-generation.
