### Vectara Introduces Factual Consistency Score for Automated Hallucination Detection Vectara has introduced the Factual Consistency Score (FCS), a calibrated score that helps developers evaluate hallucinations automatically in RAG. The FCS offers an innovative and reliable solution for detecting hallucinations, surpassing current prevalent methods such as GPT-4 or GPT-3.5. This tool provides enhanced performance, cost-effectiveness, and low latency, promoting a more efficient and accurate approach to ensuring the integrity of AI-generated content. By offering clarity and directness in evaluating factual consistency, the FCS empowers developers to refine and elevate the quality of applications ranging from internal Q&A systems to customer interactions. The score interprets probabilities directly, providing transparency and interpretability for developers and users alike.
