I find more hallucination - like when you're taught as a child to reflect back the question at the start of your answer.

If I am not careful, and "asking the question" in a way that assumes X, often X is assumed by the LLM to be true. ChatGPT has gotten better at correcting this with its web searches.

I am able to get better results with Claude when I ask for answers that include links to the relevant authoritative source of information. But sometimes it still makes up stuff that is not in the source material.
