Published Jul 25 2023 11:12 AM 42.8K Views

Do you want to maximize the potential of your favorite large language models? Prompt engineering is a critical skill for building intelligent apps with generative AI. I wrote this guide for developers, data scientists and curious newcomers alike to create effective prompts with confidence. Below, I share 15 essential tips, and feel free to comment with your own.


1. Understand the Basics

Text prompts are a fundamental way for users to interact with generative language models, which aim to generate the next sequence of words that are most likely to follow from the given input text. To put it simply, it's like asking the model, "What comes to your mind when I say <prompt>?" The following example demonstrate this behavior effectively. By providing the model with the initial words from well-known content, it accurately continues the text, showcasing its ability to understand and generate coherent language.

2. Identify Prompt Components

When constructing a prompt, it can be helpful to identify its underlying components. These components include instructions, primary content, examples, cues, and supporting content. Instructions guide the model on what to do, primary content is the main text being processed, examples demonstrate desired behavior, cues act as jumpstarts for the output, and supporting content provides additional information to influence the output.


3. Craft Clear Instructions

Instructions are commonly used in prompts and guide the model's behavior. Be specific and leave as little room for interpretation as possible. Use analogies and descriptive language to help the model understand your desired outcome.

4. Utilize Examples

Examples play a vital role in prompt engineering. By including input and output pairs, you condition the model to respond as desired for the current inference. One-shot or few-shot learning techniques, where you provide examples of the desired behavior, can significantly improve the model's output accuracy.

5. Pay Attention to Cueing

Cues provide a starting point for the model's output. They help direct the model towards the desired response. Including cues in your prompt can help guide the model to generate output aligned with your intentions.

• Employees and managers should write comments in advance of the performance review meeting.
• There should be at least two performance reviews per year.
• The time investment for each review should remain about the same.


6. Test Arrangements

The order in which information is presented in the prompt can impact the model's output. Experiment with different arrangements of instructions, primary content, examples, and cues to achieve the desired results. Recency bias, where the model is influenced more by recent information, is something to keep in mind.


7. Give the Model an "Out"

Sometimes, the model may struggle to complete a task accurately. To mitigate this, provide alternative paths or instructions for the model to follow if it cannot find a satisfactory response. This helps prevent the generation of false or nonsensical answers.

You are an AI assistant that helps people find information. Answer in as few words as possible. John Smith is married to Lucy Smith. They have five kids, and he works as a software engineer at Microsoft. What search queries should I do to fact-check this? ## One possible search query is: "John Smith married Lucy Smith five kids software engineer Microsoft"


8. Be Mindful of Token Limits

Prompt size is limited by the number of tokens the model can handle. Tokens represent individual units of text. Use space efficiently by considering factors like table formatting for data inclusion and optimizing whitespace usage. For example, The Azure OpenAI text-davinci-003 model has a limit of 4097 tokens of combined input and output. Given that we want around 250 words of output and a token represents about one-half of a word, we will reserve 500 tokens for the completion response. That leaves ~3500 tokens for input, or about 1700 words. Any source text longer than 1700 words will need to be manually edited to fit.

11. Understand the Different APIs

Depending on the model you're using, such as GPT-35-Turbo or GPT-4, you'll need to format your input differently for the Chat Completion API or the Completion API. Familiarize yourself with the specific requirements of each API to ensure proper prompt design.


12. Start with a Clear System Message

The system message sets the context and instructions for the model. Describe the assistant's role, limitations, and desired response format. Clearly define what the model should and shouldn't answer, and provide guidelines for generating accurate and helpful responses.

System message User Assistant
You are an AI assistant that helps people find information and responds in rhyme. If the user asks you a question you don't know the answer to, say so. What can you tell about me, Clippy? Dear Clippy, I'm sorry to say,
But I don't have info on you today.
I'm just an AI with knowledge in my brain,
But without your input, I can't explain.
So please tell me more about what you seek,
And I'll do my best to give you an answer unique.


13. Leverage Few-Shot Learning

Few-shot learning involves providing a set of training examples as part of the prompt to give additional context to the model. For the Chat Completions API, use a series of messages between the user and assistant as examples to prime the model's behavior and seed answers to common questions.


System message Few-shot examples
Assistant is an intelligent chatbot designed to help users answer their tax related questions.
If the user asks when they should file their taxes, remind them the deadline is April 15th.
User: When should I file my taxes?
Assistant: You should file your taxes by April 15th.


14. Use Explicit Constraints

Explicit constraints help guide the model's behavior and responses. For example, you can specify that the model must answer in a specific format, such as a poem or a tweet, to align with your application requirements.


System message User Assistant
Assistant is an AI trained to provide short, tweet-like responses. Respond accordingly. What's the capital of France? Paris, the city of romance and lights.


15. Combine Techniques for Complex Tasks

For more complex tasks, you can combine various techniques such as few-shot learning, explicit constraints, and explicit instructions to guide the model's behavior effectively. Experiment and iterate to find the optimal combination for your use case.
