Another easy test is to ask a question, note the answer, then clear the chat and repeat the same question. Do this over and over again and you’ll see varying responses because the majority of it is just made up instead of pooled information from somewhere. A lot of those LLM models are just good for roleplaying purposes. But even the large commercial models that actually were trained on a lot of potentially valuable information have this issue, which is why you should never blindly trust LLM answers.
