Mine frequently hallucinates (tells me I have a sale for instance on eBay that doesn't exist) or even gives me summaries that are literally the opposite of what's being said (so far innocuous, but I have already imagined how this could have disastrous results in a different context)
Opposite meaning is actually quite common mistake when I tried to summarize e-mails with Llama and ollama. It catches the general themes correctly, just inverts the meanings, making it useless.
