Does this app unload the image model each time it has produced the number of images you set it to make (1 by default)?
Because after testing the demo it seems like that to me, and my suggestion would be to find a way to keep the model loaded for a while longer, so one may edit the text (within a few min max) and press Start (to generate it with the changed words), without having to reload the model to memory. Is that possible? Maybe display a countdown until the model unloads from memory?
