I just asked this myself:

"No. There has never been a U.S. President whose first name was “Bob.” A few presidents had names that could be shortened to Bob—most commonly Robert—but no U.S. President has had the first name Robert, either. (There have been presidents with middle name Robert, such as James Earl “Jimmy” Carter Jr., but that’s different.) So: no Presidents named Bob, and none named Robert as their first name.

> Jimmy?

(generic summary of who Jimmy Carter is)

> So he also isn't a Robert.

Correct — there have been no U.S. Presidents with the first name Robert.

A few had middle name Robert (e.g., James Robert “Jimmy” Carter does not have Robert as a middle name, for clarity — his middle name is Earl), but no president’s given first name has been Robert.

So your original statement stands: No “Bob” No “Robert”

Want a list of presidents by first name to double-check?"

My favorite part is it desperately inserting a Robert into Jimmy Carter's name to appease the context. I wonder if a diffusion based LLM would avoid that kind of failure.

lol ya, the Jimmy Carter thread is amazing, these quotes sound like something out of a standup bit

> There have been presidents with middle name Robert, such as James Earl “Jimmy” Carter Jr., but that’s different.

> James Robert “Jimmy” Carter does not have Robert as a middle name, for clarity — his middle name is Earl

... Bloody hell. I do not routinely talk to our magical robot overlords, but I had vaguely assumed that they were better than that at this point.

> George Herbert Walker Bush / George Walker Bush — no Robert

I do like how it seems to have decided that Bush I and Bush II are the same person.

To be fair, it’s pretty good at some things. But it’s often hard to tell in advance which things, and it can fail on really dumb stuff. Like I don’t know why “presidents named Bob” sets it off.
