How to get started with ChatGPT Prompt Engineering

ChatGPT Prompt Engineering is a crucial skill set in any language model exploration. It requires a deep understanding of language models, their functioning, and competence in crafting effective prompts that steer the output towards a preferred outcome. Our Introduction to ChatGPT course is an introductory resource to grasp the fundamentals of this tool.

How ChatGPT works

ChatGPT is a transformer model that employs a prediction technique to synthesize text. It predicts subsequent words in a sentence and joins sentences to piece together full paragraphs. For example, given the context of "The sun is...", ChatGPT might predict "shining" or "setting" as suitable continuations. Understanding ChatGPT's mechanism is vital in guiding the model to generate predictions that align with your desired outcome.

Foundations of Prompt Engineering

Prompt Engineering is an iterative cycle of crafting, testing, and optimizing prompts to generate precise, targeted outcomes. It involves developing prompts that can shape the AI’s output with minimal disruptions or unnecessary responses. As such, the foundations of Prompt Engineering require a clear understanding of ChatGPT's behavior and the capacity to tailor suitable prompts to achieve accurate, useful responses. We talk more about Prompt Engineering techniques in this article.

Prompt Engineering Examples

For instance, if we want GPT-4 to produce a brief data analysis report regarding sales data for a retail source, "Provide a data analysis report" would elicit a general response. While this is adequate, we can still optimize this prompt further.

A more useful prompt could be:

"As a data analyst, sketch the methodology you would employ to scrutinize a dataset outlining sales trends over time, pinpoint best-selling products and review sales performance by region for the last quarter."

This revised prompt is specific. It carves out a role (data analyst), outlines specific requirements leading to a more effective output by instructing GPT-4 to provide specific analysis based on the specified dataset.

Strategies to craft effective prompts for ChatGPT

When designing prompts, it’s essential to understand the basic structures and formatting techniques. Prompts often consist of instructions and placeholders that guide the model’s response. 

For example, in sentiment analysis, a prompt might include a placeholder for the text to be analyzed along with instructions such as “Analyze the sentiment of the following text:” By providing clear and specific instructions, we can guide the model’s focus and produce more accurate results.

Be clear

A useful prompt should be crystal clear to guide the model's prediction accurately. Ambiguity should be minimized, with detailed prompts that clarify the exact requirements. For instance, use "Provide a detailed description of the characteristics, behavior, and care required for domestic dogs" rather than "Tell me about dogs."

Provide context

Because ChatGPT responds based on the immediate context of the question, establishing a clear context is fundamental. For example, the prompt "Translate the following English text to French: 'Hello, how are you?'" provides rough context and specific instructions.

Be precise

The precision of the prompts guides the precision of the output. Specify the expected result in the prompt. For example, to generate a list, specifically request as such: "List the top 10 most populous countries globally."

Try role-playing

ChatGPT performs optimally when adopting specific roles. Job assignment guides its response. By instructing "As a historian, explain the significance of the American Civil War" for instance, we dictate how and the depth of ChatGPT's response.

ChatGPT Prompt Examples [Bad vs. Good Prompts]

Examples of effective prompts are specific and enable the model to focus its attention on generating accurate and relevant outcomes, while bad prompts are too general and result in ambiguous or unfocused responses.

Bad Prompt: "Tell me about dogs."
Good Prompt: "Provide a detailed description of the characteristics, behavior, and care required for domestic dogs."

Bad Prompt: "Translate this text to French."
Good Prompt: "Translate the following English text to French: 'Hello, how are you?'"

Bad Prompt: "Analyze this data."
Good Prompt: "Analyze the top ten performing stocks in the technology sector for the last quarter and provide a report with projections for the next six months."

Bad Prompt: "Write an article on climate change."
Good Prompt: "As an environmental journalist, write an article on the impact of human activity on global warming, including the rise in CO2 emissions and their consequences for the environment."

Bad Prompt: "Create a chart with sales data."
Good Prompt: "Create a bar chart with the sales data for the last quarter, specifically highlighting sales growth between regions and product categories."

Examples of effective prompts are specific and enable the model to focus its attention on generating accurate and relevant outcomes, while bad prompts are too general and result in ambiguous or unfocused responses.
