Solution Overview

Problem

Existing large language models (LLMs) face inefficiencies and inaccuracies due to variations in prompt design, leading to computationally costly and resource-intensive processes when multiple prompts are used to achieve consistent output, particularly in scenarios with a large number of requests.

Innovation Solution

A prompt generation and analysis service that utilizes a classifier model to identify a preferred prompt by training on a set of target prompts, evaluating their appropriateness through comparison with expected outputs, and selecting a default or preferred prompt for subsequent LLM interactions, thereby reducing the need for multiple iterations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple prompts are used to achieve consistent output from LLM, then output reliability is improved, but computational cost and resource consumption increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-training the classifier model to understand which prompts lead to accurate LLM outputs. This advance preparation stores knowledge about prompt effectiveness, allowing the system to quickly select the most appropriate prompt without needing to submit multiple prompts during actual operation, thus maintaining accuracy while reducing processing time.

AI summary

Systems and methods for a prompt generation and analysis service for generating and identifying a preferred prompt for performing a function of a large language model (LLM) are provided. The prompt generation and analysis service may generate a set of training prompts for performing a function of an LLM. The prompt generation and analysis service may then query the LLM with the generated set of prompts and characterize the output of the LLM for each prompt. Using the characterization of the output and corresponding prompt, the prompt generation and analysis service can train a classifier model to classify the prompts. The prompt generation and analysis service may generate a set of target prompts for performing a function of an LLM, characterize the target prompts using the training classifier model, and identify a preferred prompt for performing the function based on the classifier model's classification.
