I asked OpenAI for the shortest pangram in the English language. This is its response:
> The shortest pangram in the English language is "The quick brown fox jumps over the lazy dog."
Clearly it didn't read the wikipedia article.
Then I asked for an "original pangram":
> "Fjord zoologists quip jovially, waxing lyrical about xanthic lutrines."
A Google search indicates that it may, in fact, be original.
