Is there a free AI Image Generator that actually works?

As my title indicates, there is frustration.

I am not looking for anything crazy, just making some basic still images.

The problem I have with many of them: They aren't actually free, after 1 image or 1 edit you need to pay. Lame. It rarely gets it right the first time so it needs edits.

Additionally, oftentimes the edits fail hard. I'll ask it to say add a flag in the background, and it opts to change the foreground entirely, even when told 'make no other changes'.
