New benchmark reveals faithfulness gaps in Vision-Language Models

Researchers have introduced EDCT-Bench, a new benchmark designed to identify faithfulness issues in Vision-Language Models (VLMs). This benchmark uses an intervention-based protocol called Explanation-Driven Counterfactual Testing (EDCT) to test how well VLMs' explanations and answers align with visual evidence, even after minimal edits to that evidence. EDCT-Bench covers domains such as visual question answering, driving scenarios, and 3D spatial reasoning, revealing significant gaps in model faithfulness across various VLMs. The study also suggests that counterfactuals generated by EDCT can serve as effective training signals for improving model consistency.

IMPACT Highlights potential unreliability in VLM outputs, suggesting a need for improved faithfulness in AI systems.

    EDCT-Bench: Uncovering Faithfulness Gaps in VLMs via Explanation-Driven Counterfactual Testing

    arXiv:2609.17953v1 Announce Type: cross Abstract: Vision-Language Models (VLMs) can produce Natural Language Explanations (NLEs) that sound plausible yet remain inconsistent with the visual evidence they cite. We present Explanation-Driven Counterfactual Testing (EDCT), an interv…
