Tools like ChatGPT and Bing have been skyrocketing in popularity. ChatGPT took five days since launch to reach 1 million users. Governments all over the world are trying to figure out what to do with this technology. Sweet AI-generated images are showing up everywhere; like this dog I generated using Bing:
“Can you generate a picture of an astronaut dog jumping over a fire on the moon?”
Though LLMs (Large Language Models) are still in their infancy, research has shown some pretty big productivity boosts in a range of different professions. Using metrics from Github Copilot, an AI-based coding tool, Github has found that developers complete tasks in 55% less time when taking advantage of AI.
This is all to say that LLMs are a tool we’ll need to learn to use and use well.
There are many options when choosing a LLM, with the most popular being ChatGPT and Bing. OpenAI’s ChatGPT is the most well-known, but if we want to use the latest features like ChatGPT-4 (an upgrade to ChatGPT-3) we’ll need to pay $20 a month. Microsoft has released new Bing that takes advantage of ChatGPT-4 behind the scenes and is free to use. Finally, Google has Bard which is also free to use. All offerings come with their unique pros and cons.
Regardless of which tool you use, the question remains: how do we get the most out of these tools?
Prompt Engineering
We interact with LLMs by giving them a prompt, or text input, generally in the form of a question or instruction. LLMs then reason out the answer and respond. Prompt Engineering is a term coined to describe the process of writing prompts to get the best results from LLMs. Just like in everyday conversation, the words we choose to ask in a question can dramatically change the response we get. For example, if I ask “What is the best way to get to the airport?” I’ll get a different response than asking “How do I get to the airport?“.
Throughout this article we’ll build on a prompt to create a meal plan for a single day; taking advantage of different Prompt Engineering techniques. I’ll provide the prompt used, and the response I got back from the LLM—in my case I’ll be using ChatGPT-3. Try it for yourself, but remember that the results will vary by the LLM being used.
Please create me a low sugar meal plan for one day.

Note: Remember to drink plenty of water throughout the day. Adjust portion sizes according to your specific dietary needs and consult with a healthcare professional or a registered dietitian for personalized advice.
Constraints
Just like people, LLMs need constraints and clarity to understand what’s being asking. Be specific when writing prompts, and have a desired outcome in mind. The best mental model I’ve been told is to think of LLMs as an intern, brand new to the job. They are eager to get stuff done, but need clear and direct instructions. The best way to get the best results out of LLMs is to be specific.
Let’s improve upon our prompt by adding some constraints.
Please create me a low sugar meal plan for one day. The plan should be a maximum 1,800 calories, and do not include breakfast. No gluten. High in protein.
Low-Sugar, Gluten-Free, High-Protein Meal Plan for One Day
Lunch
- Grilled chicken breast (4 oz)
- Quinoa salad with mixed vegetables (cucumber, cherry tomatoes, bell peppers) dressed with lemon vinaigrette
- Steamed broccoli (1 cup)
Snack
- Greek yogurt (6 oz) with sliced almonds (1 tbsp) and a sprinkle of cinnamon
Dinner
- Baked salmon fillet (4 oz) with garlic and herbs
- Sautéed kale (1 cup) with garlic and olive oil
- Roasted sweet potatoes (1 medium) with a sprinkle of paprika
Snack
- Celery sticks with almond butter (2 tbsp)
Dessert
-
Mixed berries (1 cup) with a dollop of unsweetened whipped cream
Note: Please note that portion sizes and specific calorie counts may vary depending on the size and brand of the ingredients used. Adjust the portion sizes and consult a healthcare professional or a registered dietitian for any specific dietary needs or concerns.
Role prompting, or “Act like a…”
Role Prompting or “Act like a …” is a technique that can be used to provide more context and constraints to LLMs.
First we tell the LLM to assume a role or persona. Then we provide a prompt.
For example, if we had a question about woodworking we might say, "Act like a master woodworker. What is the best way to cut a dovetail joint?".
Role prompting is another great way to provide constraints to LLMs.
Let’s improve upon our meal plan prompt by adding a role.

Maximum 1,800 Calories | No Gluten | High in Protein
Lunch
- Grilled chicken breast (4 oz) seasoned with herbs and spices

This meal plan is designed to be low in added sugars and gluten-free while providing ample protein from lean sources like chicken, fish, and Greek yogurt. It incorporates a variety of colorful vegetables, healthy fats from avocado and olive oil, and whole grains like quinoa for additional fiber. Remember to drink plenty of water throughout the day to stay hydrated.
Please note that this is a generalized meal plan, and it’s always a good idea to consult with a registered dietitian or nutritionist who can create a personalized meal plan based on your specific dietary needs and health goals.
Few shot prompting
Few shot prompting is my favorite technique, and can really take the performance of LLMs to the next level. First we provide the LLM with a few examples (or shots) of what we want, and then we ask the LLM to generate a similar response (furthering adding constraints to our prompt). The term “shot” is synonymous with “example”. In Pompt Engineering you will also find zero shot prompting and one shot prompting.
- Zero Shot Prompting: No examples are provided
- One Shot Prompting: One example is provided
- Few Shot Prompting: Two or more examples are provided
The shots, or examples, can be given in the same prompt, or broken out into separate prompts.
For example, in our meal plan example we could ask the LLM in a single prompt:
Use the following examples of a meal plan:

Or ask the LLM to read a few examples first before we ask our question. To reduce the amount of time needed for the LLM to repond, we can ask it to confirm once it has read the example.

Remember to drink plenty of water throughout the day and adjust portion sizes based on your individual needs and preferences. It’s also essential to include regular physical activity and maintain a balanced overall diet for optimal health.
Conclusion
Compare the first meal plan to the final result. After taking advantage of the prompt engineering techniques we learned, we can see that the last meal plan is much more specific, detailed, and closer to the answer we would expect!
Using constraints, role prompting, and shot prompting, we can improve the quality of our prompts, impress our friends, and increase our productivity.
