TLDR: To get the best results from LLMs, focus on giving clear, positive instructions, controlling response length, and using variables in your prompts. These techniques improve control, efficiency, and output quality, allowing you to fully utilize the potential of LLMs.
To get optimal results from LLMs, focus on giving clear instructions, controlling response length, and using variables in your prompts. Advanced prompt engineering gives you greater control, streamlines prompt creation, enhances output quality, and improves user experience. Also, consider prompt structure, contextual information, and iterative refinement. By mastering these techniques, you can unlock the full potential of LLMs.
Positive instructions are better than negative constraints

Recent studies highlight that using positive instructions when prompting can be more effective than focusing on constraints. Instructions clearly state the desired outcome, guiding the model on what it should do. Conversely, constraints limit the model by specifying what it should avoid.
- Tell It What To Do: Use positive instructions to clearly state the desired response format, style, or content.
- Flexibility and Creativity: Positive instructions encourage creativity and flexibility within set boundaries.
- Use Constraints Judiciously: Constraints are important for preventing harmful or biased content and enforcing strict output requirements.
- Experiment and Iterate: Test different combinations of instructions and constraints for optimal results.
Real-World Example for SMBs:
For a small marketing team aiming to leverage an LLM for social media content, specificity is key. Instead of vague directives like “Write a social media post, but don’t make it too long and don’t use jargon,” a more effective prompt would be: “Write a short and engaging social media post (under 280 characters) highlighting the key benefits of our new eco-friendly water bottle for busy parents. Use a friendly and enthusiastic tone.” This illustrates how clear instructions on tone, length, audience, and desired outcome yield better results.

Controlling LLM Output Length
The length of an LLM response can be managed effectively by either setting a maximum token limit in the model’s configuration or by explicitly requesting a specific length in your prompt.
- Configuration Settings: Most LLM platforms allow for adjusting the maximum token output. This is a global setting for a specific interaction.
- Prompt-Based Control: Desired output length can be specified within the prompt itself.
- Balance Conciseness and Completeness: Shorter output length may require prompt adjustments to include all the necessary information.
Using variables in prompts improves their reusability and adaptability

To make your prompts more reusable and dynamic, use variables instead of hardcoding specific information. By using placeholders that can be easily changed for different inputs, you can enhance the adaptability of your prompts.
Advantages of Using Variables in Prompts
- Efficiency: Eliminate the need to rewrite the same prompt repeatedly by using variables to store different values.
- Maintainability: When prompts are part of larger applications, using variables keeps the code organized and easier to update. Changes can be made to variable values without altering the prompt’s structure.
- Flexibility: Variables enable prompts to handle diverse inputs without manual adjustments. For instance, the prompt “Tell me a fact about the city: {city}” works for any city by simply changing the value assigned to the {city} variable.
