Why AI said yes to the Hulk but no to Mario

A session with our younger learners. They bring their own toys, photograph them, and ask ChatGPT to turn the photo into a scene.

One of them sets up a green toy car and a little horse with a flaming mane on the rocks outside. "Make it epic." ChatGPT hands back a comic panel: the Hulk, the car, the horse, all in it.

The next kid has a Mario figure. Same rocks, same kind of ask.

ChatGPT says no.

We're so sorry, but the image we created may violate our guardrails concerning similarity to third-party content.

Both are famous characters

Stop on that for a second. The Hulk belongs to Marvel. Mario belongs to Nintendo. Both are someone else's character. ChatGPT made one and blocked the other.

There's no clean rule there. The same kind of request, a toy turned into a scene, worked one minute and got stopped the next. The adult running the class couldn't have called it in advance.

That surprises people. We expect a computer to follow a rulebook: same input, same output. These tools don't work like that. They make a judgment in the moment about what's allowed, and the judgment moves.

What we do with it

We don't skip past the block. We talk about it.

ChatGPT stopped you. Why might that be? The answer is real: Mario is someone else's creation, not yours to remake. The tool enforced that unevenly, but the reason behind it holds.

So we point at what the best projects in the room already do: make your own. Your own character, your own world, your own idea. Copies hit a wall, sometimes the tool's, always the real one: they aren't yours. What you invent, you can build as far as you want.

The lesson under the lesson

AI makes calls, not lookups. Fast, confident, and not always the same twice.

A block is a question, not a verdict. When the tool pushes back, that's the moment to ask why, and to notice the answer often points back at you.

The decision is yours. ChatGPT can refuse a copy. It can't tell you what's worth making. That was never its job.

One kid wanted to remake Mario and hit a wall. Another built a world out of his own toys and got a comic. The difference was whose idea it was.

Making your own thing, and learning to work with the AI to do it, is what we spend a whole week on at our summer camp this July. Or try the kids' projects yourself.
