I finally saw an AI image generator make a real mistake at my office in Denver
We were using a new tool called 'CanvasFlow' to make a marketing graphic for a client's hiking gear. I typed 'a person with a backpack on a mountain trail at sunrise' and it gave me a picture with three arms. One arm was coming out of the person's chest. I had to go back and change the prompt five times, adding 'correct human anatomy' before it worked right. Has anyone else had to fight an AI to get basic stuff like the right number of limbs?

Wasn't there a whole article about how these AI image models basically learn from a giant pile of pictures and just guess what goes together? So they're not actually understanding what an arm is, they're just putting 'arm-like' shapes in 'arm-ish' places based on patterns. That's why you get extra limbs or fingers. It's just stitching together bits it's seen before without any real rules for a body. Makes total sense you'd have to spell out 'correct human anatomy' like it's a special request, which is kind of wild when you think about it.

But isn't that basically how humans learn too? We don't come out knowing what an arm is, we see a bunch of arms and figure out the pattern. The difference is we have a body and can test it. So if you showed a human a million pictures of weird medieval art with people who have six fingers, they'd probably draw that too. Models actually get better at real anatomy the more specific you get, like with "correct anatomy" prompts, which is pretty impressive when you think about how messy the internet is. Plus half the time people blame the model for bad hands when they're just bad at describing what they want.
