From my understanding its length of the conversion that causes the breakdown. As the conversation gets longer the original system prompt that contains the guardrails is less relevant. Like the weight it puts on the responses becomes less and less as the conversation goes on. Eventually the LLM just ignores it.

Oh sorry. My bad. My brain saw sure sm and inserted the sm7b where it wasn’t. Seems to be the goto microphone I see everywhere.

Sure sm7b are closer to 400 each.
