One of the biggest perks of being CNET's reviewer for AI image and video generators is how much time I get to spend with these generator tools. I've seen the absolutely wild variety of images they can spit out, including truly bizarre, wildly creepy and hilariously bad options from the likes of Midjourney or Dalle.
Don't get me wrong, AI creative software has come a long way in a short amount of time. I've created beautiful sci-fi scenes in Midjourney, realistic-looking product images with Stable Diffusion and AI-ified myself with ChatGPT. But no AI service is perfect, and I've observed some notable trends during my testing.
There are things that, despite constant updates, AI image generators simply can't handle well on the first try.

Some AI image programs give you tools to edit these mistakes, which is great. I highly recommend taking advantage of them whenever possible. For programs that don't offer those tools, or more likely, when those tools don't fix the problem, this is what you should do next.
Based on my experience, I've compiled my tried-and-true tips for tweaking your prompts and settings to optimize your images. For more, check out the best AI image generators and our guide to effective AI image prompt writing.
