Are There Any Good Entirely Free Text-to-Image AI Generators Out There?

Ive been looking for one but every decent one is locked behind a paywall of some kind. Id love one that is free with unlimited uses. I found one that fits those criteria but its quite unreliable as when I typed "a car" it kept giving pictures of chickens. I'm looking for one just for my own amusement, so i am not going to use any commercially. Any recommendations?
