New AI Guardrail Approach Filters Output, Not Just Input

A new approach to AI guardrails focuses on post-generation filtering rather than pre-generation input checks. This method utilizes 13 detectors across five categories to identify and correct issues such as fabricated citations, hallucinated tool arguments, system prompt leakage, safety refusal bypasses, and logical errors in code. The system employs 31 automatic correction strategies, with ambiguous cases flagged for human review, offering a free, model-agnostic, and CPU-only solution. AI

IMPACT This post-generation filtering approach could improve the reliability and safety of AI model outputs by catching errors that pre-generation filters miss.
