It would be way way better if they were benchmaxxing this. The pelican in the image (both images) has arms. Pelicans don't have arms, and a pelican riding a bike would use it's wings.

Having briefly worked in the 3D Graphics industry, I don't even remotely trust benchmarks anymore. The minute someone's benchmark performance becomes a part of the public's purchasing decision, companies will pull out every trick in the book--clean or dirty--to benchmaxx their product. Sometimes at the expense of actual real-world performance.

Pelicans don’t ride bikes. You can’t have scruples about whether or not the image of a pelican riding a bike has arms.

Wouldn’t any decent bike-riding pelican have a bike tailored to pelicans and their wings?

Now that would be a smart chat agent.

Sure, that’s one solution. You could also Isle of Dr Moreau your way to a pelican that can use a regular bike. The sky is the limit when you have no scruples.

Interesting that it seems better. Maybe something about adding a highly specific yet unusual qualifier focusing attention?

perhaps try a penny farthing?

I don't think that really proves anything, it's unsurprising that recumbent bicycles are represented less in the training data and so it's less able to produce them.

Try something that's roughly equally popular, like a Turkey riding a Scooter, or a Yak driving a Tractor.
