I've spent a massive amount of time living inside the world of AI image generators, and let me tell you, it's a fever dream. One minute I'm looking at a breathtaking, cinematic sci-fi landscape that looks like it cost millions to produce, and the next, I'm staring at a "hilarious" disaster where a human has three arms and teeth where their eyes should be. Tools like Midjourney, DALL-E, and Stable Diffusion have evolved at breakneck speed, but they still have some incredibly weird blind spots.
Don't get it twisted-I use these tools every day to create everything from realistic product shots to stylized avatars of myself. The tech is revolutionary, but after thousands of prompts, you start to see the cracks in the code. Despite all the "pro" updates and massive data sets, there's a specific list of things that AI still fails at with embarrassing consistency.
If you've ever tried to generate a simple group of people or a specific piece of text and ended up with a nightmare-fuel mess, you aren't alone. Even the most powerful models on the planet still struggle with basic physics and anatomy on the first go. I've identified the recurring traps that trip up even the smartest algorithms, so you can stop wasting your credits on prompts that are doomed from the start.

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.
Human faces and expressions

Accurate facial expressions continually challenge AI generators. Quirky eyes, teeth and eyebrows are some of the strongest indicators that an image is AI-generated. In this case, the result was extremely funny to me, if also completely unusable. The girls are sporting some Halloween-like vampire teeth, and the dude in the back is having more than a bad hair day.
