The CEO of the microblogging site - which was formerly known as Twitter - revealed that Grok, his new AI chatbot, is able to answer questions with some quips and jokes.
The 5x-year-old billionaire wrote on the platform: "In some important respects, it is the best that currently exists.”
Elon added that Grok “loves sarcasm” and would give solutions to queries with “a little humour”.
The Space X founder also boasted that it answers "spicy questions that are rejected by most other AI systems".
In a demonstration of the new programme - which is also plagued by the issues of other AI tools like incorrect answers and not responding with criminal advice - was asked for a recipe for cocaine.
When questioned, it replied, "just a moment while I pull up the recipe... because I'm totally going to help you with that" and gave some vague advice, instead of detailed instructions, along with sarcastic vibes.
The chatbot - which gets its name from a term from Robert A. Heinlein in his 1961 book ‘Stranger in a Strange Land’ but when - is "intended to answer almost anything and, far harder, even suggest what questions to ask" and claimed its name came from Douglas Adams’l ‘Hitchhiker’s Guide to the Galaxy’, which began life as a radio play, before becoming a book and a film.
It added that it was a "very early beta product - the best we could do with two months of training".
