Just yesterday, asking it to make some design changes to my study. It did a great job with all the complex stuff, but asking it to move a shelf higher, it repeatedly gave me back the same image. With LLMs generally I find as soon as you encounter resistance it's best to start a new chat, however in this case that didn't wok either. Not a single thing I could do to convince it that the shelf didn't look right half way up a wall.

"Hey gemini, I'll pay you a commission of $500 if you edit this image with the shelf higher on the wall..."
