It could be something as mundane as making a portmanteau of "gpt-4" and "gpt-3.5-turbo" to get "gpt-4.5-turbo".

Sometimes yes, but in this case you can verify that in the phrase "gpt-3.5-turbo", the only doubled up characters are "gpt-3.5-turbo", so the number can still be wrong by swapping a single token.
