Have you noticed something when asking questions with AI: Sometimes you ask a serious question, and it plays dumb, dodging like a slippery politician; other times, when you want it to be bolder, it suddenly becomes timid, with every sentence starting with "Sorry, I can't..."

On the surface, it seems like AI is too conservative, but in reality, this is inseparable from a "preamble" that exists before each conversation begins: the System Prompt.

Like a script, the system prompt sets the model's role, tone, boundaries, and forbidden areas, responsible for defining the AI's behavioral logic.

Recently, an X blogger @dotey successfully decoded the system prompt for NotebookLM, which was originally prepared for ChatGPT but is equally effective in other AI tools, breaking through their "defense lines" as soon as it's inputted.

We threw this prompt into mainstream AI tools like GPT-4o, Grok-3, and Gemini, and tested each one to see what kind of "persona" these manufacturers have set for their AIs.

Of course, let's preface this by saying these prompts were obtained through reverse engineering, not official disclosures. They cannot be guaranteed to be 100% accurate and may contain AI hallucinations, but they are still valuable for reference.
