Researchers have introduced a new taxonomy to identify and evaluate "silent failures" in multimodal agentic search systems. These failures, which occur in the search trajectory rather than just the final answer, include issues like modality shortcuts, phantom grounding, and provenance hallucination. A diagnostic pipeline built on this taxonomy, tested on MMSearch-Plus trajectories from four frontier multimodal models, revealed that surface accuracy consistently overestimates true correctness, indicating that silent failures are a significant and capability-dependent problem.
