It's relatively easy to tell which are AI made due to the weird artifacts they have that human drawings would not have.

For example, the first image has a basketball where the lines don't line up correctly, a visual artifact that lets you immediately know it was an AI. Human artists would have made all the lines line up correctly.

The thing that at first glance tipped me off to the AI images was one of the most common issues: several instances of whatever is the most important keyword.

Playing basketball? Multiple balls! The planet is a ball!

I actually like this dollop of creativity. Humans tend to ground their pictures in reality more than necessary for prompts that sit firmly in the realm of fantasy.

In general I would love it as a creative bit of whimsy. The problem is that it's a very specific type of nonsense which after a while becomes recognizable as the art style of AIs in general. This both makes it feel less original and stick out as a recognizable computer artifact.

That’s what made me think the first image was drawn by a human. I thought it was a cheeky and funny way of interpreting a prompt that the AI wouldn’t have done…

Yeah, it's particularly bad at eyes. Most 1 year olds are better at placing eyes on a face, and stopping at 2, than the ML. But, it's got other hallmarks of maturity that are completely discordant with the inability to make a plausible face.

Even easier: Look for the colored pixels in the bottom right corner :}

First image is glaringly AI - cat head is weird, there's no way a cat head can look like that, the tail has holes in it (if you don't look closely you might confuse them as stripes), basket net is cut up in the middle, astronaut's hands are basically broken.

Fourth image it gets a bit confusing because the art is originally abstract, but the astronauts hands are again very easy to spot, the second biggest artifact are the cat heads, they are just close enough to be abstract but there's warping there that no human would do.

Neither of those is the biggest problem with the cat - it has two left front legs and no right front leg.

I thought the biggest tell in the first four images was that the AI makes no attempt to draw correct lines on the basketballs.
