The Future of Prompt Engineering: Getting The Most Out of LLMs

Subscribe • Previous Issues

What I Talk About When I Talk About Prompting

In recent months, my approach to constructing NLP pipelines and applications has shifted from integrating various libraries to using large language models (LLMs) via their APIs. This transition has resulted in a slight increase in latency and cost (due to the replacement of free libraries), but it has also delivered significant benefits in terms of accuracy and user-friendliness. I believe that future NLP pipelines will be composed of multiple LLMs, enabling developers to select the most appropriate model for their specific task and application. The choice of LLMs is influenced by a number of factors, including the need for domain-specific models at certain stages of a pipeline, as well as performance and cost considerations tailored to specific tasks.

With this approach to building NLP pipelines, it becomes crucial to effectively compose, refine, and test prompts. Prompt engineering is the art of crafting effective input prompts to elicit the desired output from foundation models. It’s the process of crafting prompts that effectively leverage the capabilities of existing generative AI models to accomplish specific objectives. Often, this entails incorporating the task’s objective that the LLM is intended to achieve within the input, such as “provide a summary of this text”.

Prompt engineering tools need to be flexible enough to accommodate a variety of use cases, transparent so that users can understand how they work, resilient to errors, compatible with a wide range of foundation models, and user-friendly so that anyone can use them. Let me start with a few high-level observations:

  • As LLMs rapidly evolve, a standardized approach to prompt engineering is essential for fostering collaboration and streamlining the sharing of models and data. 
  • While my primary focus is on text and LLMs, users need to be able to interact with foundational models across a variety of modalities. An effective prompt engineering tool must be able to handle a variety of data types, such as text, images, and audio, and be robust to noisy data, incomplete data, and other data-related issues.
  • To facilitate collaboration and seamless sharing of models and data, prompt engineering tools must be interoperable, ensuring their compatibility with a variety of tools and platforms.
  • In the long run, it is important for prompt engineering tools to be transparent. This entails ensuring that these tools aid users in comprehending a model’s functionality, its decision-making mechanisms, and the methods by which it generates output. This will allow users to understand how their AI tools work and to make informed decisions about their use.

I decided to compile an ambitious assortment of features that could potentially improve and optimize prompt engineering for teams. Given my current focus on working with LLMs and NLP pipelines, this list may skew towards text-based applications.

Prompt engineering and management tools – key features.

It turns out that a diverse range of prompt engineering tools—with varying degrees of maturity—already exists to help engineers and researchers craft and manage prompts effectively. The following diagram offers a representative sample of such tools.

  • Prompt Inspiration: Tools for generating diverse prompts and sparking creativity.
  • Prompt Organization: Tools for managing prompts with features like folders, versioning, and team support.
  • Prompt Optimization: Tools to test and improve prompts for high-quality results.
  • AI Art Creation: Tools for crafting unique AI-generated art using prompts.
  • Metadata Visualization: Tools to log, visualize, and analyze AI metadata for insights. Metadata tools are particularly crucial for teams that integrate and chain together multiple services to build AI applications.
  • Multi-Model Interaction: Tools for integrating and interacting with multiple AI models and external services.

Some people believe that the emphasis on prompt engineering tools is misplaced, given that we are currently in a transitional phase. As LLMs continue to improve, they will not only predict words more accurately, but also become more adept at following instructions. Consequently, even simple directives will likely produce satisfactory results, thereby diminishing the significance of meticulously crafted text prompts. Despite these advancements, I maintain that formulating and managing clear, concise instructions will continue to be crucial. Just as in human communication, where different instructions can lead to different outcomes, the same will be true for large language models.

As we move forward, building software systems with LLMs will primarily involve writing text instructions. Given the importance of crafting these instructions, it is likely that we will need a subset of the features listed above. However, I believe that it is only a matter of time before many of these features are integrated into existing tools. Consequently, apart from LangChain and AimStack (AI metadata tracking tool), I have not yet integrated other prompt engineering and management solutions into my personal toolkit.
