That was pretty impressive… but do I have to be “that guy” and point out the error it made?
It said rubber ducks float because they’re made of a material less dense than water — but that’s not true!
Rubber is more dense than water. The ducky floats because it’s filled with air. If you fill it with water it’ll sink.
Interestingly, ChatGPT 3.5 makes the same error, but GPT 4 nails it and explains the it’s the air that provides buoyancy.
I had the same impression with Google’s other AI demos: cute but missing something essential that GPT 4 has.
I spotted that too, but also, it didn't recognise the "bird" until it had feet, when it is supposedly better than a human expert. I don't doubt that the examples were cherry-picked, so if this is the best it can do, it's not very convincing.
I would've liked to see an explanation that includes the weight of water being displaced. That would also explain how a steel ship with an open top is also able to float.
