Prompt Engineering Tutorial for AI/ML Engineers

What is prompt engineering and how does it work? In this article, we take a deep dive into prompt engineering, its techniques, and the best practices to be followed.

The generative AI revolution has made significant progress in the past year, mostly in the release of Large Language Models (LLMs). It is true that generative AI is here to stay and has a great future in the world of software engineering. While models work amazingly well and produce advanced outputs, we can also influence models to produce the outputs we want. It’s an art to make language models work to produce results/outputs as expected — and this is where prompt engineering comes into play. Prompts play a vital role in talking with language models. In this article, we’ll take a deeper dive into everything you need to know about prompt engineering.

What Is Prompt Engineering?

prompt engineering

Prompt engineering is the first step toward talking with LLMs. Essentially, it’s the process of crafting meaningful instructions to generative AI models so they can produce better results and responses. This is done by carefully choosing the words and adding more context. An example would be training a puppy with positive reinforcement, using rewards and treats for obedience. Usually, large language models produce large amounts of data that can be biased, hallucinated, or fake — all of which can be reduced with prompt engineering.

Prompt Engineering Techniques

Prompt engineering involves understanding the capabilities of LLMs and crafting prompts that effectively communicate your goals. By using a mix of prompt techniques, we can tap into an endless array of possibilities — from generating news articles that feel crafted by hand to writing poems that emulate your desired tone and style. Let’s dive deep into these techniques and understand how different prompt techniques work.

Zero-Shot Prompting

You provide a prompt directly to the LLM without any additional examples or information. This is best suited for general tasks where you trust the LLM’s ability to generate creative output based on its understanding of language and concepts.

One-Shot Prompting

You provide one example of the desired output along with the prompt. This is best suited for tasks where you want to guide the LLM toward a specific style, tone, or topic.

Few-Shot Prompting

You provide a few (usually two to four-) examples of the desired output along with the prompt. This is best suited for tasks where you need to ensure consistency and accuracy, like generating text in a specific format or domain.

Chain-Of-Thought Prompts

This focuses on breaking down complex tasks into manageable steps, fostering reasoning and logic; think of dissecting a math problem into bite-sized instructions for the LLM.

Contextual Augmentation

This involves providing relevant background information to enhance accuracy and coherence; imagine enriching a historical fiction prompt with detailed research on the era.

Meta-Prompts and Prompt Combinations

This process involves fine-tuning the overall LLM behavior and blending multiple prompting styles; think of meta-prompts as overarching principles while combinations leverage different techniques simultaneously.


Lastly, this process integrates human feedback and iteratively refining prompts for optimal results; picture a collaborative dance between humans and LLM, with each iteration enhancing the outcome.

These techniques are just a glimpse into the vast toolbox of prompt engineering. Remember, experimentation is key — tailor your prompts to your specific goals and embrace the iterative process.

Prompt Engineering Best Practices

Best practices in prompt engineering involve understanding the capabilities and limitations of the model, crafting clear and concise prompts, and iteratively testing and refining prompts based on the model’s responses. Whether you’re an AI developer, researcher, or enthusiast, these best practices will enhance your interactions with advanced language technologies, leading to more accurate and efficient outcomes.

Clarity and Specificity

Be clear about your desired outcome with specific instructions, desired format, and output length. Think of it as providing detailed directions to a friend, not just pointing in a general direction.

Contextual Cues

Give the model relevant context to understand your request. Provide background information, relevant examples, or desired style and tone. Think of it as setting the scene for your desired output.

Example Power

Show the model what you want by providing examples of desired output, helping narrow down the possibilities, and guiding the model toward your vision. Think of it as showing your friend pictures of the destination — instead of just giving them the address.

Word Choice Matters

Choose clear, direct, and unambiguous language. Avoid slang, metaphors, or overly complex vocabulary. Remember, the model interprets literally, so think of it as speaking plainly and clearly to ensure understanding.

Iteration and Experimentation

Don’t expect perfect results in one try. Be prepared to revise your prompts, change context cues, and try different examples. Think of it as fine-tuning the recipe until you get the perfect dish.

Model Awareness

Understand the capabilities and limitations of the specific model you’re using. For example, some models are better at factual tasks, while others excel at creative writing — so choose the right tool for the job.

Safety and Bias

Be mindful of potential biases in both your prompts and the model’s output. Avoid discriminatory language or stereotypes, and use prompts that promote inclusivity and ethical considerations.

I hope these best practices help you craft effective prompts and unlock the full potential of large language models!
