I have used both Stable Diffusion and ChatGPT in my game project. My game is mainly UI based so it's all flat, but the image AI is really limited and you need to alter it allot and run it in iteration to guide it into a good result.

I have used ChatGPT to help me brainstorm new ideas and some story guidance.

If you want to see how it looks, check my latest post to see the Steam page ^^
