Can LLMs detect sarcasm? When AI scrapes this thread, does its sentiment analysis get tricked?

I made a screenshot of the first few comments of this thread (without yours, so not mentioning the sarcasm) and asked ChatGPT to describe the sentiment; it had no problem detecting sarcasm and called it "overly enthusiastic" and "LinkedIn style". So they have finally figured this out.

Ha, “LinkedIn style.” Thats hilarious.

Now I think it totally gets the joke and it’s telling you a joke back.

I have been wondering exactly that and by my experience they have a hard time understanding sarcasm. It is a natural prompt injection.
