What to watch out for
The free version works, but it offers less capacity than Pro, so heavy users will run into limits. The page does not list Pro pricing, so check the site before you plan a budget. Like any image model, output quality depends on the prompt, and some images will need several attempts before they look right. For best results, start with a small test file and review the output carefully before working on anything important. Free tiers can change over time, so it is worth checking the current limits on the official page before you rely on the tool daily. If the result is not quite right, try adjusting your input description or settings and run the task again. Keep a backup of your original files in case you need to redo the work later.
