Solution Overview

Problem

Existing large language models (LLMs) lack attribution data for generated outputs, leading to issues like hallucinations and inefficient manual validation of checkpoints, and current validation methods are slow, costly, and inaccurate.

Innovation Solution

Implement a prompt and content generation service that includes a reference validation component to provide attribution data by searching for tokens in a curated training set and a model validation component to execute use case scenarios, ensuring accurate and efficient validation of LLM outputs.

Engineering Contradictions & Design Principles

1Measurement precision

If manual validation of LLM checkpoints is performed, then validation can be conducted, but it is slow, costly, and inaccurate

Engineering Contradiction:
Improvevalidation accuracyVSAvoidvalidation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service validation by automatically executing use case scenarios against LLM checkpoints and comparing outputs to expected results. The validation component autonomously determines pass/fail status without requiring manual intervention, thereby improving accuracy while reducing time and cost associated with manual validation processes

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by automatically comparing generated outputs against expected outputs from use case scenarios. The validation component receives feedback on whether generated references match training data tokens and provides automated determination of checkpoint validity, enabling continuous improvement without manual verification

Inventive Principle:
Principle #23Feedback

2Reliability

If LLMs generate outputs without attribution data, then generation speed is maintained, but hallucinations occur and validation becomes difficult

Engineering Contradiction:
Improveoutput reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system introduces an intermediary validation component that mediates between the LLM generation process and the verification process. This component automatically searches training data for tokens matching generated references, provides attribution data without requiring changes to the core LLM architecture, and maintains reliability by verifying output accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary action by pre-processing training data into a searchable format with tokens that can be quickly matched against generated outputs. This preparation enables fast validation without requiring complex real-time analysis during the generation process, maintaining speed while improving reliability through pre-established reference frameworks

Inventive Principle:
Principle #10Preliminary action

AI summary

Systems and methods are provided for a prompt and content generation service to validate checkpoints of large language models (LLMs). The prompt and content generation service may execute use case scenarios against checkpoints of LLMs using a prompt and expected output regarding each of the use case scenarios. The prompt and content generation service may then retrieve or receive generated outputs by the LLMs to compare against the expected outputs for each use case scenario. By comparing the expected outputs to the generated outputs, the prompt and content generation service may determine a degree of matching for each use scenario and an overall score taking into the account the degree of matching for all of the use case scenarios.
