Omni‑SafetyBench is a new benchmark designed to evaluate the safety of Omni‑Modal Large Language Models (OLLMs) that process visual, auditory, and textual data. It contains 23,328 test instances across 24 modality variations derived from 972 seed samples, and introduces metrics such as Safety‑score (based on Conditional Attack Success Rate and Conditional Refusal Rate) and Cross‑Modal Safety Consistency score. Evaluation of 11 state‑of‑the‑art OLLMs shows severe vulnerabilities, with only three models achieving a Safety‑score above 0.6 and safety degrading sharply for audio‑visual inputs, underscoring the need for improved safety alignment methods.
arXiv:2608. 05381v1 Announce Type: new Abstract: Current Multimodal Large Language Models (MLLMs) can process diverse sensory inputs, yet their reasoning remains heavily biased toward a dominant modality, resulting in brittle cross-modal reasoning.
TRIAD is a new benchmark designed to test omni‑modal large language models’ ability to resolve ambiguity across text, vision, and audio. Each item consists of a text–image–audio triplet, a question, and answer options, constructed so that the full triplet yields a unique answer while any single modality removed makes the answer ambiguous. The benchmark includes 327 queries in 86 scene groups, covering 18 ambiguity categories, and shows that current models lag humans in scene‑level disambiguation, especially when answer options are removed.
arXiv:2609.36798v1 Announce Type: cross Abstract: Omni-modal large language models (LLMs) are expected to answer a question using the modality it explicitly refers to. However, existing training para...
TRIAD is a new benchmark designed to test omni‑modal large language models’ ability to resolve ambiguity across text, vision, and audio. Each item consists of a text–image–audio triplet, a question, and answer options, crafted so that all three modalities together yield a unique answer while any single modality leaves the answer ambiguous. The benchmark contains 327 hand‑written queries in 86 scene groups, covering 18 ambiguity categories, and shows that current models lag humans significantly in scene‑level disambiguation, especially when answer options are removed.
