Negative prompts suppressing unwanted elements in the output

Remember the correct answer, the negative prompt.
・It explicitly states elements that should not be included in the output (specific words, styles, subjects, and so on) and suppresses them.
・It is used to avoid undesirable results and bring the output closer to the intent.
The system prompt (overall role and policy), maximum number of tokens (upper limit on length), and batch inference (execution method) are none of them the specification that suppresses unwanted elements.
