How Many Counterfactuals Does It Take? Probing VLM Hallucinations Through Circuits and Causal Effects
arXiv:2606.08777v1 Announce Type: new Abstract: Visual Language Models (VLMs) are known to produce hallucinated predictions that are not grounded in visual evidence, yet existing approaches lack a principled understanding of how robust such predictions are under counterfactual perturbations. In this work, we study the sample complexity of counterfactual robustness for hallucinated outputs in VLMs. We define a causal influence metric based on log-probability differences between factual, counterfactual, and activation-patched runs, and use it to characterize the stability of hallucinated predict
The proliferation of Visual Language Models and their increasing deployment in sensitive applications necessitates a deeper understanding of their failure modes, particularly hallucinations, to build trustworthy AI systems.
Understanding and quantifying the robustness of VLM hallucinations is crucial for developing reliable AI, enabling more secure and predictable applications across various sectors.
This research provides a principled method to evaluate hallucination robustness, moving beyond anecdotal observations toward a more scientific and quantifiable approach to VLM safety and reliability.
