arXiv:2607.01420v1 Announce Type: new Abstract: As grounded QA systems are increasingly deployed in AI assistants, accurately attributing generated answers to evidence is critical for user trust and model safety. While unimodal attributions have been explored in depth, the multimodal setting remains relatively under-researched. As a result, we introduce MultAttnAttrib, a training-free attribution-generation method that leverages a model's prefill pass, selected attention heads, and calibrated thresholds to locate source evidence within a document. To establish baseline results for the method,
The increasing deployment of grounded QA systems in AI assistants necessitates improved attribution methods for trustworthiness and safety, a critical problem as AI models become more complex and integrated into daily operations.
Accurate multimodal attribution directly impacts user trust, model safety, and the responsible deployment of advanced AI, especially for systems handling sensitive or critical information derived from long documents.
This new method offers a training-free approach to multimodal attribution, potentially reducing development costs and accelerating the deployment of more explainable AI systems by leveraging existing model components.
