As you notice, we gave users a lot of quota/credit when generating through Form especially for paid users. In short, it's actually because the images are being generated directly in the browser.

Sometimes when generating images in Form you'll face some issues in the file result or browser tab being unresponsive.
It's actually caused by our method of how we generate images in Form.

Using Form, you're generating the images directly in the browser and not using the server.
That is one of a reason why we can give many quotas to you in Form.

With “Use Image Request Quota“ checked, your Form items will be generated in the server
which makes it faster, more stable, and can generate hundreds of images at once but
with consequences of using your Image Request quota and not your form request quota

Reason why we add an option to use your image request quota instead of your form when generating the images
