Our paid plans come with a set number of volts per month, allowing you to generate up to four images at a time at the fastest speed. The number of volts varies based on your plan:

Once you’ve used up all your volts for the month, you can still generate an unlimited number of images at relaxed speeds, one image at a time, based on GPU availability (typically one image per minute).

There is no way to manually switch between fast and relaxed generation speeds. Once you run out of fast generations, you will automtically switch to relaxed generation speeds.
