Prompt Engineering and Design Patterns

In Simple terms:

Prompt engineering is like giving specific instructions to a smart computer to get the exact information or response you want. Imagine you're talking to a really clever robot, and you want it to help you in the best possible way. To do that, you need to tell it exactly what you need, step by step.

For example, if you want the robot to write a story about a cat, you wouldn't just say, "Write a story." Instead, you might say, "Tell a story about a curious cat named Whiskers who goes on an adventure in a magical garden." This way, you guide the robot and make sure it understands what you're looking for.

You can also set some rules for the robot. If you're asking it to write about a topic, you can add conditions like, "Make sure the story is happy and not sad." This helps the robot know the kind of story you prefer.

And just like when you talk to a friend and share more details as the conversation goes on, you can interact with the robot in steps. For example, you might ask it to define a word first and then use that definition to explain a concept. It's like having a back-and-forth conversation to get the best results.

So, prompt engineering is about being clear, adding some rules, and interacting with the smart computer in a way that helps you get exactly what you're looking for. It's a bit like being the director of a play, guiding the actors (or in this case, the computer) to create the perfect performance (or response).

In Technical Terms:

Prompt engineering is a technique used to guide the behavior of language models, particularly large language models like GPT-3. It involves designing and formulating prompts in a way that influences the model's responses to generate desired outputs. The goal is to elicit more accurate, coherent, and contextually relevant information from the language model.

Language models like GPT-3 are powerful, but they operate based on the input they receive. Users can shape this input, known as prompts, to achieve specific outcomes. Prompt engineering involves experimenting with different ways of framing prompts, adjusting parameters, and incorporating contextual cues to obtain the desired results.

Some common techniques used in prompt engineering include:

1. Explicit Instruction: Clearly instructing the model on how to approach a task.

2. System Query: Asking the model to think through a problem step by step or debate pros and cons.

3. Temperature and Top-k Sampling: Adjusting parameters to control the randomness of the model's output.

4. Domain Priming: Specifying the domain or context of the desired response.

5. Redirection: Refining, rephrasing, or adding constraints to prompt the model towards desired outcomes.

6. Multi-step Interactions: Involving a series of prompts and responses to facilitate dynamic, conversational exchanges.

7. Constraint Application: Applying explicit boundaries in the prompt to control AI behavior and mitigate biases.

8. Scaffolding: Breaking down a prompt into smaller, more focused questions or instructions to maintain focus and coherence.

9. "Act As" Instruction: Instructing the model to adopt alternate personalities or roles.

10. Structured Data Input: Leveraging the model's ability to analyze and process structured data.

Prompt engineering is often an iterative process that involves testing and refining prompts to achieve the desired level of performance. It is commonly used in various applications such as content generation, language translation, question answering, and more. The effectiveness of prompt engineering depends on the specific goals of the user and the characteristics of the language model being utilised.

Prompt Engineering Design Patterns In Detail:

1. Scaffolding Pattern:

The Scaffolding Pattern in prompt engineering involves breaking down a complex prompt into smaller, more manageable parts or instructions. This helps guide the language model through a step-by-step process, ensuring a more focused and coherent response.

Here's an example of how we might apply the Scaffolding Pattern in prompt engineering:

Original Prompt: "Write an essay on artificial intelligence."

Scaffolded Prompts:

• "Begin by defining artificial intelligence and its primary goals."
• "Discuss the historical evolution of AI, highlighting key milestones."
• "Explain the current applications of AI in various industries."
• "Explore the ethical considerations and potential challenges of AI."
• "Conclude by summarizing the future prospects and developments in artificial intelligence."

2. Redirection Pattern:

The Redirection Pattern in prompt engineering involves refining, rephrasing, or adding constraints to prompts to guide AI-generated responses towards desired outcomes. It's a strategy used to channel the language model's creativity or focus its attention on specific aspects of a task. This pattern allows users to influence the model's outputs by adjusting the way they frame their requests.

Here's an example to illustrate the Redirection Pattern:

Original Prompt: "Describe the benefits of a healthy lifestyle."

Redirection prompts:

• "List three specific habits that contribute to a healthy lifestyle (e.g., balanced diet, regular exercise, and sufficient sleep)."
• "Elaborate on the long-term benefits of each mentioned habit, considering physical and mental well-being."

3. Multi-step Pattern:

The Multi-Step Pattern in prompt engineering involves structuring interactions with language models as a series of prompts and responses. Instead of presenting a single, standalone prompt, users engage in a back-and-forth exchange with the model, creating a dynamic and evolving conversation. This pattern facilitates more context-aware outputs, allowing users to guide the model through a sequence of steps to achieve a desired outcome.

Here's an example to illustrate the Multi-Step Pattern:

Prompt 1:

• "Define artificial intelligence."

Prompt 2 (based on response to Prompt 1):

• "Explain three applications of artificial intelligence in healthcare."
• "Provide real-world examples of how AI is transforming the finance industry."

4. Constraint Pattern:

The Constraint Pattern in prompt engineering involves setting explicit boundaries or conditions within the prompt to guide the behavior of the language model and ensure that the generated output adheres to specific criteria. By introducing constraints, users can control the model's responses, mitigate potential biases, or tailor the content to meet certain requirements.

Here's an example to illustrate the Constraint Pattern:

Original Prompt: "Write a news article about autonomous vehicles."

Modified with Constraint:

• "Ensure that the article focuses on the safety aspects and ethical considerations of autonomous vehicle technology."
• "Include perspectives from both supporters and critics of autonomous vehicles."

5. "Act As" Pattern:

The "Act As" Pattern in prompt engineering involves instructing the language model to adopt alternate personalities or roles when generating responses. This pattern leverages the versatility of the model to simulate the viewpoint or communication style of a specific character, persona, or historical figure.

Here's an example to illustrate the "Act As" Pattern:

Original Prompt: "Act as a historical figure and write a letter describing the challenges faced during your time."

Example: "Act as Abraham Lincoln and write a letter detailing the challenges of the Civil War era."

6. Structured Data Pattern:

The Structured Data Pattern in prompt engineering involves leveraging the capabilities of language models to analyze and process structured data. Instead of relying solely on natural language prompts, this pattern incorporates specific data formats or structured information within the input to guide the language model's responses.

Here's an example to illustrate the Structured Data Pattern:

Original Prompt: "Analyze the sales data provided and identify the top-selling products."

Structured Data:

• Provide a table with columns for product names, sales figures, and categories.
• Based on the data, identify the top-selling products and explain any trends or patterns observed.

7. Fallback Pattern:

The Fallback Pattern in prompt engineering involves incorporating contingency plans or alternative approaches into prompts to manage unexpected or unsatisfactory responses from language models. This pattern serves as a way to handle situations where the initial prompt might not yield the desired outcome or where the model's response may not meet the user's expectations.

Here's an example to illustrate the Fallback Pattern:

Original Prompt: "Compose a poem about the beauty of nature."

Fallback Prompts:

• If the response is unsatisfactory, add a fallback prompt like, "If you were a poet, how would you describe the serenity of a forest at dawn?"
• "Alternatively, write a short paragraph capturing the essence of a tranquil natural setting."
