Is there a term for this?

Has anyone ever had this happen, with any LLM model really, where its given a code snippet and then literally says something blatantly incorrect about it?

Dumbed down example:

Prompt: "why isn’t the text red?

<.font color=red>test<./font>"

Response: "The reason the text is not red, is because you need to use the font html tag with the color property set to red.

Your code:
<.font color=red>test<./font>

Change it to:
<.font color=red>test<./font>

If you need anything else, let me know!"

I feel like something specific im doing is causing this sometimes, but cant figure out what…
