Overconfident
Moronic
Jargoneer
as a Service

Jargoneer: because it can lean all the field-relevant jargon, tend to over-use some terms and generally has good grammar (unlike me ).
Moronic: because it can repeat and summarize true truths, thanks to its good education, but fundamentally fail to understand any of if, and can also pull complete bullshit out of thing air.
Overconfident: because it is not able to differentiate stuff learned from a reliable source, from stuff it hallucinated, and will present it all as obvious facts if it matches the prompt defined by its audience.
