Solution Overview
Problem
Existing foundational models for generative artificial intelligence require significant resources for retraining or fine-tuning, which can be impractical and lead to a proliferation of task-specific models that are resource-intensive to maintain.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retraining or fine-tuning is performed to improve model performance on specific tasks, then task-specific performance is improved, but computational resources and time are consumed
Solution Approach 1:
The patent changes the parameter being optimized from model weights to prompt parameters. Instead of modifying the foundational model through retraining or fine-tuning, the system iteratively refines prompt inputs to achieve task-specific performance. This involves translating prompts between different modalities (e.g., text to image and back) and using the differences to guide prompt modifications, thereby improving performance without consuming extensive computational resources for model retraining.
2Reliability
If retraining or fine-tuning is performed to improve model performance on specific tasks, then task-specific performance is improved, but the complexity of model maintenance increases due to proliferation of task-specific models
Solution Approach 1:
The patent makes the single foundational model universal across multiple tasks by refining prompts rather than creating separate task-specific models. The cycle-consistent translation approach enables one model to adapt to different tasks through prompt engineering, eliminating the need to maintain multiple specialized models and reducing overall system complexity.
Solution Approach 2:
Instead of modifying model architecture or weights to create task-specific variants, the patent changes only the prompt parameters. This allows a single foundational model to serve multiple tasks by adjusting input prompts through cycle-consistent refinement, avoiding the proliferation of task-specific models and their associated maintenance complexity.
3Reliability
If prompts are manually adjusted through prompt engineering to achieve desired output, then task performance is improved, but human time and effort are consumed
Solution Approach 1:
The patent implements self-service by automating the prompt refinement process. The system performs cycle-consistent translations (e.g., text to image to text) and automatically identifies differences between original and translated prompts, then iteratively modifies prompts based on these differences without requiring human intervention. This eliminates the need for manual prompt engineering while achieving task-specific performance.
Solution Approach 2:
The patent introduces feedback loops where the output of cycle-consistent translations is compared with the original input, and the differences feed back into prompt modifications. This automated feedback mechanism replaces manual human evaluation and adjustment, enabling the system to self-optimize prompts iteratively without consuming human time and effort.

AI summary
This disclosure presents a technique for enhancing the performance of models such as large multimodal models (LMMs) without retraining or fine-tuning. This technique includes an iterative refinement process implemented by three main components: a forward generator, a backward generator, and a discriminator. The forward generator translates a prompt into an output in a different modality, the backward generator translates this output back into the original modality, and the discriminator compares the prompt and the translated prompt to generate a hint for refining the prompt to reduce differences. This cycle continues until the original prompt and the translated prompt match, achieving cycle consistency. The solution offers several advantages, including improving model performance without the need for costly fine-tuning, training data, or expertise. It simplifies system complexity by not relying on external environments like compilers and APIs and uses cycle consistency as a supervisory signal to iteratively refine a prompt.
