A new offline disaster app called HeliGO has been developed, utilizing an on-device AI model named Edge-4B-TELL, which is based on Gemma-4 E4B. This app is designed to function without any network connectivity, meaning it cannot rely on external servers or larger models for verification. To ensure the trustworthiness of its responses in critical situations, HeliGO employs a three-stage safety gate system that wraps the AI model. This system blocks potentially fatal outputs, substitutes official guidance text when available, and ultimately refuses to answer if confidence remains low, as the model's self-reported confidence has been found to be unreliable and even inverted in critical scenarios.
