Janitor AI's official guide says 'don't talk for me' often backfires, because the model reads it literally and writes more about your character.
Define the AI as a narrator separate from you and the characters, and put that role first in the prompt.
Write your own turns with actions, thoughts and a clear stopping point so the bot has no gap to fill.
Use an instruction tag such as 'task: pause chat|roleplay, answer query(...)' for out-of-character requests like recaps.
With DeepSeek, temperature may have no effect while thinking mode is on, so rely on the prompt and a max-token cap.
