Flexible Prompt Guardrails System for Generative AI
Summary
USPTO published patent application US20260099719A1 for a flexible and extensible prompt guardrails system for generative AI. The system intercepts prompts intended for a generative AI system, extracts feature vectors using specialized models, and evaluates them against rules to determine whether to block or allow the prompt. The system supports adding or removing features and updating evaluation rules based on testing. The application was filed on October 3, 2024.
What changed
USPTO published patent application US20260099719A1 disclosing a flexible and extensible prompt guardrails system for generative AI. The system comprises a feature extraction module that extracts feature vectors from prompts using specialized models, and a feature evaluation module that applies rules to determine whether to block or allow prompts and generates appropriate responses for blocked prompts. The system architecture supports adding or removing features as needed and updating evaluation rules based on testing results.
For technology companies developing AI systems, this patent application indicates potential intellectual property considerations in AI safety and content moderation technologies. Companies implementing prompt filtering or guardrails for generative AI may want to monitor this application's prosecution for potential freedom-to-operate implications.

Abstract
A prompt guardrails system comprising a feature extraction module and a feature evaluation module is a flexible and extensible system for determining whether to block or allow prompts from being communicated to a generative artificial intelligence (AI) system. When the prompt guardrails system detects/intercepts a prompt intended for the generative AI system, the feature extraction module extracts a feature vector for the prompt using specialized models for each feature or set of features and the feature evaluation module determines whether to block or allow the prompt and, for a blocked prompt, a response to provide using rules applied to the feature vector. The feature extraction module can add or remove features as they are engineered or deemed low importance, and the feature evaluation module can update rules to be higher quality based on testing of the prompt guardrails system.
