Prompt engineering is the art and science of crafting effective inputs for large language models (LLMs) like GPT-4 to obtain desired outputs. As AI technology advances, the ability to communicate effectively with these models becomes increasingly important. This guide aims to share strategies and tactics that can help you achieve better results from LLMs, whether you're using them for personal projects, business applications, or research purposes.
The methods described in this article can often be combined for greater effect, and experimentation is encouraged to find the approaches that work best for your specific needs. It's worth noting that some examples may only work with the most capable models, such as GPT-4. If you find that a model struggles with a particular task, trying a more advanced model might yield better results.
“ Six Strategies for Better Results
To optimize your interactions with large language models, we've identified six key strategies:
1. Writing clear instructions
2. Providing reference text
3. Splitting complex tasks into simpler subtasks
4. Giving models time to "think"
5. Using external tools
6. Testing changes systematically
Each of these strategies comes with specific tactics that can be implemented to improve your results. Let's explore each strategy in detail.
“ Writing Clear Instructions
Clear communication is crucial when working with AI models. Unlike humans, these models can't read between the lines or infer unstated preferences. To get the best results, it's important to be explicit and detailed in your instructions.
Tactics for writing clear instructions include:
1. Including details in your query for more relevant answers
2. Asking the model to adopt a specific persona
3. Using delimiters to clearly indicate distinct parts of the input
4. Specifying the steps required to complete a task
5. Providing examples of desired outputs
6. Specifying the desired length of the output
For instance, if you want brief replies, explicitly ask for them. If you need expert-level writing, state that requirement. If you prefer a specific format, demonstrate it in your prompt. The more specific you are, the less the model has to guess, and the more likely you are to get the output you want.
“ Providing Reference Text
Language models can sometimes generate confident but incorrect answers, especially for esoteric topics or when asked for citations and URLs. To mitigate this, providing reference text can be incredibly helpful.
Tactics for providing reference text include:
1. Instructing the model to answer using a specific reference text
2. Asking the model to answer with citations from the reference text
By giving the model reliable information relevant to the current query, you can guide it towards more accurate and well-supported responses. This approach is particularly useful when dealing with specialized knowledge or when you need to ensure the model's output aligns with specific sources of information.
“ Splitting Complex Tasks
Just as in software engineering, breaking down complex problems into smaller, manageable components can lead to better results when working with language models. Complex tasks often have higher error rates, but by decomposing them into simpler subtasks, you can improve accuracy and manageability.
Tactics for splitting complex tasks include:
1. Using intent classification to identify the most relevant instructions for a user query
2. Summarizing or filtering previous dialogue for long conversations
3. Summarizing long documents piecewise and constructing a full summary recursively
This approach allows you to handle more intricate problems by addressing each component separately, reducing the likelihood of errors and improving the overall quality of the output.
“ Giving Models Time to Think
Like humans, AI models can benefit from taking time to work through problems step-by-step rather than rushing to a conclusion. This approach can lead to more accurate and well-reasoned responses.
Tactics for giving models time to think include:
1. Instructing the model to work out its own solution before concluding
2. Using inner monologue or a sequence of queries to hide the model's reasoning process
3. Asking the model if it missed anything on previous passes
By encouraging the model to take a methodical approach, you can often obtain more reliable and thoughtful answers, especially for complex problems or those requiring multi-step reasoning.
“ Using External Tools
While language models are powerful, they have limitations. Integrating external tools can help compensate for these weaknesses and enhance the model's capabilities.
Tactics for using external tools include:
1. Using embeddings-based search to implement efficient knowledge retrieval
2. Employing code execution for accurate calculations or calling external APIs
3. Giving the model access to specific functions
By leveraging external tools, you can expand the model's functionality, improve its accuracy in specific domains, and create more robust and versatile AI-powered applications.
“ Testing Changes Systematically
To ensure that changes to your prompts or system design actually improve performance, it's crucial to test them systematically. This involves creating comprehensive evaluation procedures or "evals".
Tactics for systematic testing include:
1. Evaluating model outputs with reference to gold-standard answers
2. Designing evals that are representative of real-world usage
3. Including a large number of test cases for statistical significance
4. Automating the evaluation process where possible
By implementing rigorous testing procedures, you can confidently optimize your AI system's performance and make data-driven decisions about which changes to implement.
“ Conclusion
Prompt engineering is a powerful skill that can significantly enhance your interactions with large language models. By applying the strategies and tactics outlined in this guide – writing clear instructions, providing reference text, splitting complex tasks, giving models time to think, using external tools, and testing changes systematically – you can improve the quality, reliability, and usefulness of AI-generated outputs.
Remember that the field of AI is rapidly evolving, and what works best may change over time. Stay curious, keep experimenting, and don't hesitate to adapt these techniques to your specific use cases. With practice and persistence, you'll be able to harness the full potential of language models and create more effective AI-powered solutions.
