Optimizing LLM Cascades with Prompt Design

LLM Cascades

The following business outcomes must be achieved by these strategies.

  • Delivering high-quality answers to a greater number of users initially.
  • Higher levels of user support should be offered while protecting data privacy.
  • Enhancing cost and operational effectiveness through timely economization.

Eduardo outlined three methods that developers could use:

  • Different prompt techniques are used in prompt engineering to produce answers of a higher caliber.
  • By adding more context to the prompt, retrieval-augmented generation makes it better and less taxing on end users.
  • The GenAI pipeline moves data more efficiently when prompt economization techniques are used.

Quickly improving the quality of the results while cutting down on the number of model inferencing and associated costs is possible with effective prompting.

Quick engineering: Enhancing model output

Let’s begin by discussing the Learning Based, Creative Prompting, and Hybrid prompt engineering framework for LLM Cascade.

The one shot and few shot prompts are included in the learning-based technique. This method provides the model with context and teaches it through the use of examples in the learning prompt. A zero-shot prompt is one that queries the model using data from its prior training. Context is provided by a one-shot or few-shot prompting, which teaches the model new information so that the LLM produces more accurate results.

More accurate responses can be obtained by using strategies like iterative prompting or negative prompting, which fall under the Creative Prompting category. While iterative prompting offers follow-up prompts that enable the model to learn over the course of the series of prompts, negative prompting sets a boundary for the model’s response.

The above methods can be combined, or not, in the Hybrid Prompting approach.

These approaches have benefits, but there is a catch: in order to generate high-quality prompts, users must possess the necessary knowledge to apply these strategies and provide the necessary context.


Typically, LLM Cascade are trained using a broad corpus of internet data rather than data unique to your company. Results from the LLM workflow prompt that incorporate enterprise data with retrieval augmented generation (RAG) will be more pertinent. In order to retrieve the prompt context, this workflow entails embedding enterprise data into a vector database. The prompt and the retrieved context are subsequently sent to the LLM, which produces the response. Your data stays private and you avoid paying extra for compute training since RAG allows you to use your data in the LLM without retraining the model.

Early economization: Saving costs and delivering value

The final technique focuses on various prompt strategies to reduce the amount of inferencing needed for the model.

  • Token summarization lowers costs for APIs that charge by the token by using local models to reduce the number of tokens per user prompt sent to the LLM service.
  • Answers to frequently asked questions are cached by completion caching, saving inference resources from having to be generated each time the question is posed.
  • Query concatenation reduces overhead that accumulates per-query, such as pipeline overhead and prefill processing, by combining multiple queries into a single LLM submission.
  • LLM cascades are designed to execute queries on more basic LLMs initially, rating them according to quality, and only moving on to more expensive, larger models when necessary. By using this method, the average compute requirements per query are decreased.

Ultimately, the amount of compute memory and power determines the model throughput. However, accuracy and efficiency are just as important in influencing the outcomes of generative AI as throughput. The above strategies can be combined to create an LLM Cascade prompt architecture that is specific to your company’s requirements.

Although large language models (LLMs) are immensely potent instruments, they can be optimized to function more effectively just like any other tool. Prompt engineering can help in this situation.

Prompt engineering

The skill of crafting input for an LLM Cascade to produce the most accurate and desired result is known as prompt engineering. It basically provides the LLM Cascade with precise instructions and background information for the current task. Prompts with thoughtful design can greatly enhance the following:


A well-crafted prompt can guide the LLM Cascade away from unrelated data and toward the information that will be most helpful for the given task.


The LLM Cascade can determine the solution more quickly and with less computation time and energy if it is given the appropriate context.


By giving precise instructions, you can make sure the LLM produces outputs that are suited to your requirements, saving you time from having to sort through pointless data.

Prompt Engineering Technique Examples

Here are two intriguing methods that use prompts to enhance LLM performance

Retrieval-Augmented Generation

This method augments the prompt itself with pertinent background knowledge or data. This can be especially useful for assignments that call for the LLM to retrieve and process outside data.

Emotional Persuasion Prompting

Research indicates that employing persuasive prompts and emotive language can enhance LLM concentration and performance on creative or problem-solving tasks.

You can greatly improve the efficacy and efficiency of LLMs for a variety of applications by combining these strategies and experimenting with various prompt structures.
