Solution Overview

Problem

Existing large language models (LLMs) struggle to maintain standards for their outputs due to constantly evolving information and challenges in dynamically updating validation models without complete rebuilding, leading to potential violations of standards or offensiveness.

Innovation Solution

A computing platform trains an LLM steward model using historical information to classify LLM outputs as acceptable, tolerable, or non-acceptable, and updates the model dynamically through a feedback loop based on user feedback and updated information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a closed loop validation model is used for LLM outputs, then validation consistency is maintained, but dynamic updates become difficult without complete model rebuilding

Engineering Contradiction:
Improvevalidation consistencyVSAvoidmodel update complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The validation model is segmented into a base model component and a dynamic regime component. The base model maintains the closed-loop validation consistency, while the dynamic regime component can be updated independently through regime switching mechanisms, allowing updates without complete model rebuilding.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces dynamic regime switching capability that allows the validation model to adapt to changing standards and information. The model can transition between different validation regimes based on updated information, enabling dynamic updates while preserving the core validation framework.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If validation standards are constantly updated to reflect evolving information, then validation accuracy improves, but model maintenance difficulty increases

Engineering Contradiction:
Improvevalidation accuracyVSAvoidmodel maintenance difficulty
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The validation model incorporates dynamic regime switching that allows it to adapt to evolving validation standards. When standards change, the system can switch to updated regimes rather than requiring complete model reconstruction, maintaining high validation accuracy while reducing maintenance complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms that monitor changes in validation standards and trigger appropriate regime transitions. This automatic feedback loop ensures the model maintains accuracy with evolving standards while reducing manual maintenance burden through automated adaptation.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If complete model rebuilding is performed to incorporate updates, then model accuracy is maintained, but computational resources and time are wasted

Engineering Contradiction:
Improvemodel accuracyVSAvoidupdate efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

By segmenting the model into static base components and dynamic regime components, the system allows selective updates of only the necessary regime portions rather than rebuilding the entire model, preserving accuracy while significantly improving update efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system prepares multiple validation regimes in advance, allowing quick switching between them when updates are needed. This preliminary preparation of alternative regimes enables rapid model updates without complete rebuilding, maintaining accuracy while improving productivity.

Inventive Principle:
Principle #10Preliminary action

AI summary

A computing platform may train, using historical information indicating a plurality of regimes for LLM outputs, an LLM steward model, which may configure the LLM steward model to generate LLM validation information indicating classifications of LLM outputs as acceptable/tolerable/non-acceptable. The computing platform may input, into an LLM, an LLM prompt, which may cause the LLM to generate an LLM output. The computing platform may input the LLM output into the LLM steward model, which may cause the LLM steward model to output the LLM validation information. Based on outputting LLM validation information indicating that the LLM output is acceptable/tolerable, the computing platform may send the LLM output to a user device for presentation. Based on outputting LLM validation information indicating that the LLM output is non-acceptable, the computing platform may update the LLM output to conform with a corresponding subset of the plurality of regimes.
