How to prevent LLM to act like a robot/assistant?

I'm playing with a conversational agent I made using either api/generate or api/chats. In both case I do ask him to not ask follow up question, to not act like an assistant, etc. Either from a system prompt, or a system message. Yet, it doesn't work. I tried different models just in case but no difference. Any tips ? submitted by /u/what-pos [link] [comments]
