Can I generate images on Free? How many per day?

Yes. On Free, you can generate 1K images with GPT Image 2 at Low quality. The images carry a MyVocal watermark. You can generate up to 5 successful images per day; the limit resets at 00:00 UTC. Generation uses characters at the price shown, so you need enough characters even if you have images left today.

A batch counts by image, not by click. Images in progress temporarily use a slot; a failed image releases its slot. In the Image workspace, you can check both how many images you have left today and how many characters the next generation costs.
