# Instant Image
### Super fast text to Image Generator.
### <span style='color: red;'>You may change the steps from 4 to 8, if you didn't get satisfied results.
### First Image processing takes time then images generate faster.
### Must Try -> Instant Video https://huggingface.co/spaces/KingNish/Instant-Video
