Anything that needs to overcome concepts which are disproportionately represented in the training data is going to give these models a hard time.

Try generating:

- A spider missing one leg

- A 9-pointed star

- A 5-leaf clover

- A man with six fingers on his left hand and four fingers on his right

You'll be lucky to get a 25% success rate.

The last one is particularly ironic given how much work went into FIXING the old SD 1.5 issues with hand anatomy... to the point where I'm seriously considering incorporating it as a new test scenario on GenAI Showdown.

Surprisingly, it got all of them right

Some good examples there. The octopus one is at an angle - can't really call that one pass (unless the goal is "VISIBLE" tentacles).

Other than the five-leaf clover, most of the images (dog, spider, person's hands) all required a human in the loop to invoke the "Image-to-Image" capabilities of NB Pro after it got them wrong. That's a bit different since you're actively correcting them.

It mostly depends on "how" the models work. Multi-modal unified text/image sequence to sequence models can do this pretty well, diffusion doesn't.

Multimodal certainly helps but "pretty well" is a stretch. I'd be curious to know what multimodal model in particular you've tried that could consistently handle generative prompts of the above nature (without human-in-the-loop corrections).

For example, to my knowledge ChatGPT is unified and I can guarantee it can't handle something like a 7-legged spider.

I just got the model to generate a spider without a leg by saying "Spider missing one leg" and it did it fine. It won't do it "every time", (in my case 1 out of 2), but it will do it. I used the GPT-image-1 model in the api. I don't think they are actually running a full end to end text/image model sequence model. I don't think anyone really is commercially, they are hybrids as far as I know. Someone here probably has better information on the current architectures.

You didn't correct the hands being backwards? It gave you a man with six fingers on his right hand, and four fingers on his left.
