The Tone Of The Prompt

TL;DR:

In the context of Large Language Models (LLMs), the tone of a prompt can be conveyed through formal language, informal language, or an assertive style. A formal tone employs polite and professional language, as in “Kindly provide an update on the project status.” An informal tone adopts a casual and conversational style, such as “Can you give me the lowdown on the latest gossip?” An assertive tone expresses confidence and directness, like “State your position clearly and support it with evidence.” By considering the desired tone, users can shape the LLM’s response style. For example, a formal prompt may elicit a more professional and reserved response, while an informal prompt might encourage a more relaxed and colloquial reply. The tone of the prompt sets the overall atmosphere of the interaction, influencing the LLM’s behavior and guiding the level of formality or informality in the generated responses.


The tone of a prompt refers to the overall attitude or feeling conveyed by the language and style used in the prompt. It can range from formal and serious to casual and playful, and can greatly influence how the AI ‘perceives’ the intent of the prompt. The tone of a prompt should be carefully considered in order to achieve the desired response from the AI.

For example, a prompt that is written in a formal and serious tone may be more effective at conveying information and establishing credibility. This tone is often used in academic or professional settings, where the end reader expects a certain level of formality and professionalism. On the other hand, a prompt that is written in a more casual and playful tone may be more effective at engaging a reader and eliciting an emotional response. This tone is often used in marketing or advertising, where the goal is to connect with the reader on a personal level.

It is important to note that the tone of a prompt should be appropriate for the intended audience and context. Using an inappropriate tone can lead to misinterpretation or the alienation of a reader. Additionally, the tone should be consistent throughout the prompt in order to avoid confusion or conflicting messages being conveyed to the AI.

Overall, the tone of a prompt is a critical aspect of prompt engineering and should be carefully considered in order to achieve the desired outcome. By selecting an appropriate tone for the audience and context, prompt engineers can create prompts that are effective at eliciting a response and achieving their intended goal.

A Serious Tone

The language used in a prompt with this tone should be clear, concise, and direct. The focus is on providing the end reader with relevant and accurate information, rather than on engaging them emotionally.

In order to achieve a serious and informative tone, prompt engineers may use language that is more formal and technical in nature. This can include using complex vocabulary, avoiding contractions, and adhering to grammatical conventions. Additionally, it may be necessary to provide additional context or background information in order to fully convey the intended message.

While a serious and informative tone may be appropriate in certain contexts, it is important to ensure that the prompt remains engaging and relevant to the end reader / person consuming the output. This can be achieved by using examples or illustrations to help clarify complex concepts, or by highlighting the practical applications of the information being presented.

Overall, a serious and informative tone in a prompt can be effective at establishing credibility and conveying important information, as long as it is used appropriately and the final output remains engaging to the reader, assuming that is the objective.

We will provide examples of tonality in the final section of this module, in the meantime here are three examples of variations in the tone of a prompt:

  • Serious tone: serious tone is reflected through the choice of words and the gravity of the topics addressed.
  • Formal tone: “Please provide a detailed explanation of your research methodology.”
  • Informal tone: “Hey, could you tell me a bit about how you did your research?”
  • Assertive tone: “I need you to explain your research methodology in detail.”
