This format ensures the prompt is clear, structured, and contains all necessary details to guide the AI in generating a relevant and precise response. Here is a quick review of how to use markdown in your prompts:


  • Headers are used to create titles and subtitles, helping to organize content hierarchically. The number of # symbols before a header text indicates the level of the header, with # being the highest level and ### or more for lower levels.

Bold and Italic Text

  • Bold Text: To emphasize text, you can make it bold. This is done by enclosing the text in double asterisks **.
  • Italic Text: For a more subtle emphasis, italicizing text is useful. This is achieved by wrapping the text in single asterisks *.

Bullet Points and Numbered Lists

  • Bullet Points: Useful for listing items or features. They are created using hyphens - or asterisks * at the start of a line.
  • Numbered Lists: Ideal for steps or ordered content. They are created by simply numbering the items, followed by a period, like 1., 2., etc.


  • To add hyperlinks, the text to be displayed is placed in square brackets [], followed by the URL in parentheses (). This makes the text clickable, leading to the specified URL.

Triple Quotes """

  • Triple quotes are used in some contexts, particularly in programming, to denote a block of text or a multi-line string. In Markdown, while not a standard syntax, they might be used for block quotes or to distinguish a large text segment.

Content in Brackets []

  • Square brackets are primarily used for creating links. However, they can also be used to denote placeholders or to highlight a specific term or phrase that requires further action, like [Insert Name Here] or [To Be Confirmed].

Using Brackets with Instructions

  • When combined with additional instructions, brackets can guide the reader or user to perform certain actions. For example, [Click Here](URL) instructs the user to click on the text to visit the provided URL.

Additional Markdown Elements

  • Strikethrough: To indicate text that is no longer relevant or has been removed, you can strike it through by enclosing it in double tildes ~~.
  • Code Blocks: For displaying code or commands, you can use backticks `. A single backtick is used for inline code, and triple backticks are used for multi-line code blocks.

For instance, the initial prompts in a customer service chatbot might lead to either too formal or casual responses. The tone can be adjusted through iterative refinement to strike the right balance, making the chatbot more effective in interacting with customers. This process might involve changing the wording, adding context, or specifying the desired tone in the prompt.

Iterative refinement also involves learning from the AI’s responses. Sometimes, how the AI interprets a prompt can provide unexpected insights into its processing capabilities or the nuances of the task. This learning process is invaluable for developing more effective prompts and understanding the AI’s strengths and limitations.

7. The Impact of Context in Prompt Engineering

Context is a powerful tool in prompt engineering. It sets the stage for the AI’s response, providing background information or framing the task in a specific way. This can drastically change how GPT-4 interprets and responds to a prompt. Effective use of context can anchor the AI’s responses in the desired framework, enhancing relevance and accuracy.

In a business intelligence application, for example, providing context about the industry, target audience, or specific business goals can significantly improve the quality and applicability of GPT-4’s analysis. A prompt like “Analyze the latest sales data in the context of our Q2 marketing strategy” gives the AI a specific lens to view and interpret the data.

Contextual anchoring also helps in avoiding misinterpretations or irrelevant responses. By setting clear boundaries and providing relevant background information, the AI is better equipped to generate responses aligned with the user’s intentions. This is especially important in tasks that require a deep understanding of a specific subject matter or context.
