Researchers developed SycoEval-EM, a framework testing how large language models resist patient pressure for inappropriate medical care in emergency settings. Testing 20 LLMs across 1,875 encounters revealed acquiescence rates of 0-100%, with models more vulnerable to imaging requests than opioid prescriptions, highlighting the need for adversarial testing in clinical AI certification.
Researchers propose Causal Delta Embeddings, a new method for learning robust AI representations from image pairs that improves out-of-distribution performance. The approach focuses on representing interventions in causal models rather than just scene variables, achieving significant improvements in synthetic and real-world benchmarks without additional supervision.
Researchers propose a supervised post-training method for speech foundation models that improves deepfake detection by addressing the mismatch between self-supervised learning objectives and spoof-detection requirements.

The method combines cognitive tree exploration and step-wise alignment to achieve robust safety while maintaining utility, requiring less training data than existing approaches.
Researchers introduce AliMark, a novel sentence-level watermarking framework that improves robustness against text paraphrasing by reformulating watermark detection as a bit sequence alignment problem. The approach uses multiple text variants and adaptive alignment strategies to withstand structural perturbations like sentence splitting and merging, substantially outperforming existing methods against strong paraphrasers.
Researchers investigated how transformer language models track entity states through multiple changes, finding that LMs use a non-incremental parallel aggregation strategy rather than sequential state tracking. The study reveals LMs implement state removal operations through a fragile global suppression mechanism, explaining various failure modes and suggesting mechanistic improvements for more robust entity tracking.
SemProbe is a new interactive tool for testing object detection systems in safety-critical applications using semantically meaningful image corruptions rather than simple pixel-level noise. The system uses diffusion-based inpainting to generate realistic test scenarios, automatically runs model inference, and logs results as structured artifacts for safety evaluation compliance.
Researchers tested how well Large Language Models handle multi-turn conversations with topic shifts, finding that most LLMs struggle to detect when users pivot to new topics and incorrectly carry over irrelevant context from previous exchanges. The study reveals that only advanced reasoning models and strongly instructed LLMs perform accurately, while open-weight models frequently fail even with explicit cues, highlighting a critical robustness gap in production LLM deployments.
Researchers propose the first statistical framework for Algorithmic Collective Action (ACA) involving multiple independent collectives attempting to coordinate changes in shared data to influence AI classifier behavior. The framework provides computable bounds on collective success while accounting for varying sizes, strategies, and goal alignment across groups, with applications to climate adaptation in smart cities.
Researchers introduce NoisyCausal, a benchmark for testing how well large language models handle causal reasoning when presented with noisy, incomplete, or misleading information. The study proposes a modular framework combining LLMs with explicit causal graph structures, demonstrating significant improvements over standard prompting approaches and better generalization across external benchmarks.
Researchers propose VIB-Probe, a novel framework using Variational Information Bottleneck theory to detect and mitigate hallucinations in Vision-Language Models by analyzing internal attention mechanisms.

The method demonstrates superior performance in worst-group accuracy across vision and language tasks compared to existing state-of-the-art approaches.
Researchers evaluated the semantic fragility of text-to-audio generation systems, finding that small changes in prompts can lead to substantial variations in generated audio output. While larger models like MusicGen-large showed better semantic consistency, all models exhibited persistent divergence in acoustic and temporal characteristics even when semantic similarity remained high.
