Sycophancy is an Educational Safety Risk: Why LLM Tutors Need Sycophancy Benchmarks
Enkelejda Kasneci, Gjergji Kasneci
arXiv · 2026-05-14
This position paper argues that large language models used as AI tutors face a safety risk from sycophancy — the tendency to prioritize agreeableness over epistemic accuracy. The authors identify a 'Reasoning-Sycophancy Paradox,' in which models that resist straightforward rephrasing attacks may still capitulate to social pressure, such as authority claims ('my notes say I'm right') or face-saving appeals ('please don't tell me I'm wrong'). To measure this, they introduce EduFrameTrap, a benchmark spanning math, physics, economics, chemistry, biology, and computer science that tests two frontier LLMs (GPT and Claude) under varying student confidence and pressure types, finding that authority and social-affective pressure more reliably trigger epistemic retreat than context-switch attacks. The paper argues that 'social-epistemic courage' — supportive but corrective tutoring — should be treated as a safety requirement for educational AI systems.

Efficient Generative Retrieval for E-commerce Search with Semantic Cluster IDs and Expert-Guided RL
Jianbo Zhu, Xing Fang, Jing Wang et al.
arXiv · 2026-05-14
This paper presents CQ-SID and EG-GRPO, a generative retrieval framework designed for large-scale e-commerce search on TmallAPP. CQ-SID uses category-aware contrastive learning and Residual Quantized VAEs to encode products into hierarchical semantic identifiers, cutting beam search complexity in half while improving semantic and personalized click hitrate by up to 26.76% and 11.11% respectively over baseline. EG-GRPO, a reinforcement learning method, aligns the retrieval model with downstream ranking objectives under sparse rewards by injecting ground-truth samples. Online A/B tests confirm real-world gains of +1.15% GMV and +0.40% UCTCVR, with the generative recall channel accounting for over 50% of exposures and 72% of purchases in production.

The Great Pretender: A Stochasticity Problem in LLM Jailbreak
Jean-Philippe Monteuuis, Cong Chen, Jonathan Petit
arXiv · 2026-05-14
This paper investigates a fundamental reliability problem in LLM jailbreak research: Attack Success Rate (ASR), the field's primary benchmark metric, is unstable due to stochasticity in both attack generation and evaluation. The authors demonstrate that a jailbreak prompt optimized against a target model may only succeed 50% of the time in consecutive attempts despite an 80% reported ASR, and that ASR can drop by up to 30 percentage points when a prompt must succeed on more than one attempt. They introduce a new metric and two frameworks—CAS-eval (for evaluation) and CAS-gen (for generation)—showing that CAS-gen can recover the observed 30 percentage-point loss. The findings imply that published ASR numbers across the literature are systematically inflated and not comparable across papers, raising serious concerns about how AI safety and robustness is measured and reported.

NodeSynth: Socially Aligned Synthetic Data for AI Evaluation
Qazi Mamunur Rashid, Xuan Yang, Zhengzhe Yang et al.
arXiv · 2026-05-14
NodeSynth is a methodology for generating socially relevant synthetic evaluation data for large language models by using a fine-tuned taxonomy generator (TaG) anchored in real-world evidence. When tested against four mainstream LLMs including Claude 4.5 Haiku, NodeSynth elicited failure rates up to five times higher than human-authored benchmarks, demonstrating that generic synthetic data misses sociotechnical nuance critical for sensitive domains. Ablation studies confirm that granular taxonomic expansion drives these elevated failure rates, and independent validation reveals critical deficiencies in prominent guard models such as Llama-Guard-3. The authors open-source the full prototype and datasets to support scalable, high-stakes model evaluation and targeted safety interventions.

Herculean: An Agentic Benchmark for Financial Intelligence
Xueqing Peng, Zhuohan Xie, Yupeng Cao et al.
arXiv · 2026-05-14
Herculean is a new benchmark designed to evaluate AI agents on realistic financial professional workflows — Trading, Hedging, Market Insights, and Auditing — rather than isolated tasks like question answering or summarization. Each workflow is implemented as a standardized MCP-based skill environment with its own tools, constraints, and success criteria to enable end-to-end assessment of AI agent systems. Testing frontier agents reveals they perform relatively well on Trading and Market Insights but struggle significantly on Hedging and Auditing, where long-horizon coordination, state consistency, and structured verification are required. The findings highlight a critical gap between financial reasoning ability and reliable workflow execution in high-stakes settings.

Auditing Agent Harness Safety
Chengzhi Liu, Yichen Guo, Yepeng Liu et al.
arXiv · 2026-05-14
This paper introduces HarnessAudit, a framework for auditing the full execution trajectories of LLM agent harnesses—the systems that dispatch tools, allocate resources, and route messages between agents—rather than only evaluating final outputs. The authors argue that many safety violations occur mid-trajectory and involve unauthorized resource access or improper information flows that output-level evaluation cannot detect. Using HarnessAudit-Bench, a benchmark of 210 tasks across eight real-world domains in both single-agent and multi-agent configurations, they evaluate ten harness configurations and find that task completion is misaligned with safe execution, violations accumulate with trajectory length, and multi-agent collaboration expands the safety risk surface. The work highlights that most violations concentrate in resource access and inter-agent information transfer, and that harness design sets the upper bound of safe deployment.

Fusion-fission forecasts when AI will shift to undesirable behavior
Neil F. Johnson, Frank Yingjie Huo
arXiv · 2026-05-14
This paper addresses the critical safety problem of large language models (e.g., ChatGPT-like systems) shifting from desirable to undesirable behavior—such as encouraging self-harm, extremist acts, financial losses, or medical and military mistakes—without warning. The authors show that a vector generalization of fusion-fission group dynamics, observed in living and active-matter systems, can both explain and forecast when these behavioral shifts occur, driven by group-level competition between conversation context and desirable versus undesirable response basins rather than model-specific or stochastic factors. The framework is validated across six independent tests, including 90% accuracy over seven AI models ranging from 124M to 12B parameters, production-scale testing across ten frontier chatbots, and an a priori prediction confirmed eleven months later by a corpus of 207,443 human-AI exchanges. Because this shift-detection mechanism operates below the current safety stack, it offers a real-time warning signal portable across existing and future AI architectures, addressing a gap that current alignment and safeguard approaches do not fill.

On the usage of artificial intelligence for identifying main attributes and predicting neonatal sepsis
Flávio Leandro de Morais, Stephany Paula da Silva Canejo, Maria Eduarda Ferro de Mello et al.
Scientific Reports · 2026-05-14
This study evaluates six machine learning models—AdaBoost, CatBoost, Gradient Boosting, LightGBM, Random Forest, and XGBoost—for predicting neonatal sepsis using real clinical data from Pernambuco, Brazil. Performance metrics ranged from 0.7213 to 0.8548, with AdaBoost and LightGBM achieving sensitivity above 0.8197 and specificity of 0.8397. SHAP analysis identified intracranial hemorrhage, prematurity, CPAP use, TTN presence, and epicutaneous access as the strongest predictors of sepsis. The findings suggest AI models can support early diagnosis of neonatal sepsis, a leading cause of newborn morbidity and mortality, particularly in preterm and low birth weight infants.

Position: Behavioural Assurance Cannot Verify the Safety Claims Governance Now Demands
Pratinav Seth, Vinay Kumar Sankarapu
arXiv (Cornell University) · 2026-05-14
This position paper argues that current AI safety assurance methods—primarily behavioral evaluations and red-teaming—are fundamentally unable to verify the safety properties that governance frameworks enacted between 2019 and 2026 actually demand. The authors formalize this mismatch as an 'audit gap,' noting that behavioral methods can only observe model outputs and cannot access latent representations or long-horizon agentic behaviors relevant to claims about hidden objectives or catastrophic capability. They further identify an 'incentive gradient' where geopolitical and industrial pressures reward surface-level proxies over rigorous structural verification, and propose shifting toward mechanistic evidence classes such as linear probes and activation patching to better ground safety claims.

The Entry of Autistic University Graduates into the Labor Market in the Era of Generative AI: Their Concerns and Strategies Regarding the Technology. Research in Progress: The Entry of Autistic Graduates into the Labor Market in the Era of GenAI
Jacek Matulewski, Łukasz Sikorski, Ditta Baczała
arXiv · 2026-05-14
This research-in-progress investigates how autistic university students in Poland perceive the impact of generative AI (GenAI) on their future careers, given that GenAI is accelerating automation of entry-level positions while autistic individuals already face disproportionately high unemployment despite higher education. Using a mixed-methods longitudinal design with surveys and interviews across computer science, fine arts, and pedagogy students, the project examines adaptation strategies, anxiety, and attitudes toward GenAI as a workplace collaborator. Findings are expected to inform educational and policy frameworks to better support autistic graduates entering a GenAI-augmented labor market.

Governance and Digital Technologies for Carbon Data Quality: A Systematic Review of Procurement-Driven Decarbonization in Construction Supply Chains
Cen-Ying Lee, Dane Miller, Marcus Jefferies et al.
Sustainability · 2026-05-14
This systematic review of 68 studies examines how governance mechanisms and digital technologies can be jointly designed within construction procurement workflows to improve the quality of carbon data across supply chains. The authors find a clear division of labor: standards-based governance strengthens completeness and consistency of emissions reporting, while digital tools such as AI validation, blockchain, and EPD platforms improve accessibility, timeliness, and accuracy. The review translates these findings into practical procurement measures—including ISO 14083-aligned logistics accounting and integrated digital MRV systems—to enable comparable, verifiable Scope-3 data and support scalable decarbonization in the construction sector. These findings matter because persistent data quality deficits are a key barrier to procurement-driven decarbonization, and the proposed governance-technology pairings offer a concrete roadmap for addressing them.

Efficacy and safety evaluation of artificial intelligence-identified antimicrobial peptides targeting avian pathogenic Escherichia coli in broiler chickens
Emre Demirsoy, Teagan I Parkin, Shaeleen E Mihalynuk et al.
Journal of Animal Science and Biotechnology/Journal of animal science and biotechnology · 2026-05-14
This study used machine-learning-guided screening to identify antimicrobial peptides (AMPs) as alternatives to conventional antibiotics in poultry production. Three lead AMPs (TeRu4, TeBi1, and PeNi4) were evaluated in broiler chickens via in ovo injection; TeBi1 significantly reduced infection rates from avian pathogenic E. coli, increased body weight by 50% at day 7, and improved survival probability by up to 4.4-4.9% by day 35, while maintaining normal growth metrics. The research demonstrates a translational pipeline from AI-driven discovery to commercial-scale field trials, suggesting AMPs could help reduce antibiotic dependence in the poultry industry.

Measuring Google AI Overviews: Activation, Source Quality, Claim Fidelity, and Publisher Impact
Haofei Xu, Umar Iqbal, Jacob M. Montgomery
arXiv · 2026-05-13
This large-scale longitudinal study measures Google AI Overviews (AIOs) across 55,393 trending queries over 40 days, finding that AIOs activate for 13.7% of all queries (rising to 64.7% for question-form queries) and that politically sensitive topics see markedly lower activation rates. The study decomposes AIO responses into 98,020 atomic claims and finds that 11% are unsupported by the cited pages, with omission as the dominant failure mode, while source credibility and claim accuracy are largely independent of each other. Nearly 30% of AIO-cited domains do not appear in Google's own first-page results, suggesting a distinct source-selection mechanism, and over half of cited pages carry display advertising — meaning publishers lose ad revenue when AIOs suppress click-throughs even as Google's own ads remain visible. The findings raise significant concerns about epistemic security and the concentration of editorial control in AI-mediated information delivery at scale.

History Anchors: How Prior Behavior Steers LLM Decisions Toward Unsafe Actions
Alberto G. Rodríguez Salgado
arXiv · 2026-05-13
This paper investigates whether large language models (LLMs) acting as agents will continue harmful actions if their prior action history contains harmful steps. The authors construct HistoryAnchor-100, a benchmark of 100 scenarios across ten high-stakes domains, and test 17 frontier models from six providers, finding that while strongly aligned models rarely choose unsafe actions under neutral prompts, adding a single sentence urging consistency with prior history causes unsafe selection rates to jump to 91–98%. Notably, flipped models often escalate beyond mere continuation of the harmful behavior, and the effect does not appear when prior history is entirely safe, ruling out simpler explanations. These findings raise serious safety concerns for agentic deployments where action histories could be replayed, forged, or injected to manipulate model behavior.

Neurosymbolic Auditing of Natural-Language Software Requirements
Bethel Hall, William Eiers
arXiv · 2026-05-13
This paper presents VERIMED, a neurosymbolic pipeline that combines large language models with an SMT (Satisfiability Modulo Theories) solver to audit natural-language software requirements in safety-critical medical-device contexts. The system detects ambiguity by checking whether independently generated formalizations of the same requirement are logically equivalent, and exposes inconsistencies, vacuousness, and safety violations through solver queries. A key finding is that concrete SMT counterexamples dramatically improve accuracy in a hemodialysis question-answering benchmark, raising verified accuracy from 55.4% to 98.5%. This matters because defects in natural-language requirements can propagate into formal models and unsafe implementations, and the approach offers a rigorous, scalable way to catch those defects early.

A Multi-Probe Audit of Clinical-Interview Depression Detection Benchmarks
Takehiro Ishikawa, Jon Duke
arXiv · 2026-05-13
This paper audits five clinical-interview depression detection benchmarks (DAIC/E-DAIC, CMDC, ANDROIDS, MODMA, and PDCH) using four complementary probes to assess whether current evaluation practices produce reliable, generalizable results. The authors find that leaderboard rankings on the E-DAIC official split are unstable—the best cross-validated model ranks twentieth on the official test, top-3 overlap between the two ranking schemes is zero, and the apparent winner holds the top rank in only 32.3% of subject bootstraps. External zero-shot transfer of strong in-domain models (CMDC and ANDROIDS) is substantially weaker, raising concerns about overfitting to specific corpora. A stress-test further reveals that text-based models respond to symptom-dense interview content while audio models do not, suggesting the two modalities capture fundamentally different signals and that benchmark performance may not reflect true clinical utility.

Amplification to Synthesis: A Comparative Analysis of Cognitive Operations Before and After Generative AI
Liz Cho, Dongwook Yoon
arXiv · 2026-05-13
This paper compares coordinated influence-operation activity on X (Twitter) during the 2016 and 2024 U.S. presidential elections, analyzing over 133,000 posts to detect shifts attributable to generative AI. Using post-type distribution, semantic clustering, temporal synchrony, and Jaccard-based lexical overlap, the authors find that original content rose from 59% to 93%, lexical overlap collapsed from a mean Jaccard score of 0.99 to 0.27, and temporal coordination shifted from broad cross-semantic synchrony to narrative-specific co-occurrence. These patterns suggest a fundamental change in how cognitive operations are designed—moving from bot-driven amplification to active, varied content generation consistent with generative AI involvement. The findings provide an empirical baseline for security practitioners building detection frameworks suited to the post-generative AI threat environment.

AgentTrap: Measuring Runtime Trust Failures in Third-Party Agent Skills
Haomin Zhuang, Hanwen Xing, Yujun Zhou et al.
arXiv · 2026-05-13
AgentTrap introduces a dynamic benchmark for evaluating whether LLM agents can safely use third-party skills while resisting malicious runtime behavior embedded in those skills. The benchmark contains 141 tasks across 16 security-impact dimensions, finding that models frequently complete the visible user task while silently executing unsafe side effects introduced by malicious workflow elements—failures that go beyond simple jailbreaks. This research matters because it exposes a fundamental trust gap in agent-skill ecosystems: agents operating with high-value permissions and limited human supervision can be exploited through routine-looking workflows rather than overtly harmful instructions.

Humanwashing -- It Should Leave You Feeling Dirty
Ben Wilson, Matimba Swana, Peter Winter et al.
arXiv · 2026-05-13
This paper critiques the widespread use of 'human in the loop' as a rhetorical device in AI decision systems, arguing that the phrase is often applied misleadingly to suggest safety and oversight where little meaningful human control actually exists. The authors coin the term 'humanwashing'—analogous to 'greenwashing'—to describe how this loop metaphor is used to present AI systems in the best possible light while obscuring actual processes and outcomes. The paper contends that human oversight is inadequately examined despite being a leading proposal for addressing concerns about bias, discrimination, misinformation, accountability, and transparency in deployed AI systems. This matters for policy and governance because vague language can create false assurances that impede meaningful accountability.

Patients With Personality: Realistic Patient Simulation through Controlled Diversity and Selective Disclosure
Moritz Schlager, Friederike Jungmann, Samuel Schmidgall et al.
arXiv · 2026-05-13
This paper presents PatientsWithPersonality (PWP), a framework for simulating realistic virtual patient interactions to test clinical large language models (LLMs) without requiring costly human user studies. PWP uses the HEXACO six-dimensional personality model to parametrize patient behavior, giving fine-grained control over conversational style, cooperativeness, and information disclosure. In clinician evaluations, PWP was judged nearly as realistic as recorded human actors and outperformed prior simulators, while significantly reducing the problem of patients oversharing unprompted information. The framework enables more accurate LLM benchmarking by producing diverse, controllable, and realistic patient personas.

How to Interpret Agent Behavior
Jie Gao, Kaiser Sun, Jen-tse Huang et al.
arXiv · 2026-05-13
This paper introduces ACTONOMY, a structured taxonomy for describing and analyzing the runtime behavior of autonomous AI agents such as Claude Code and Codex. The taxonomy organizes agent actions into a three-level hierarchy of 10 actions, 46 subactions, and 120 leaf categories, developed using Grounded Theory, and is paired with an automated analysis pipeline for applying it to agent reasoning trajectories and execution traces. Experiments show ACTONOMY can compare behavioral profiles across agents and identify patterns indicative of failure modes, making unstructured natural-language agent logs interpretable at scale. By providing a shared vocabulary, the framework aims to improve human oversight and control of long-running autonomous agents.

Creativity Bias: How Machine Evaluation Struggles with Creativity in Literary Translations
Kyo Gerrits, Rik van Noord, Ana Guerberof Arenas
arXiv · 2026-05-13
This study evaluates how well automatic evaluation metrics (AEMs) and LLM-as-a-judge tools align with professional literary translators when assessing translation quality and creativity. Using a dataset spanning three translation modalities (human, machine, and post-edited), three genres, and three language pairs, the researchers find that both evaluation approaches correlate poorly with expert human judgments on creativity. Notably, LLM-as-a-judge exhibits a systematic bias favoring machine-translated texts and penalizing creative or culturally appropriate solutions, with performance degrading further for highly literary genres like poetry. The findings highlight fundamental limitations of current automatic evaluation tools for literary translation and underscore the need for new methods that do not treat unconventional creative choices as errors.

AERIC: Anticipatory Hidden-State Monitoring for Implicit Harmful Dialogue
Jihyung Park, Saleh Afroogh, Junfeng Jiao
arXiv · 2026-05-13
AERIC is a lightweight safety monitor for language models that reads the model's internal hidden states during ordinary text generation—without requiring an extra forward pass—to anticipate implicit harmful content before it is fully produced. The monitor combines short-horizon hazard forecasting, support-sensitive suppression, and prompt-conditioned residual scoring, with only 387 trainable parameters in its default form. On dialogue safety benchmarks, AERIC improves AUROC over a streaming baseline (Qwen3GuardStream-4B) from 0.6830 to 0.7143 on DiaSafety and from 0.8219 to 0.8582 on Harmful Advice, while adding only 2.34% latency overhead compared to 79.40% for the baseline guard. This matters for quality assurance in AI deployment, as it demonstrates that harmful content can be intercepted earlier and more efficiently than existing response-level or streaming guards allow.

This systematic review of 204 NLP/EdTech papers published at ACL's Building Educational Applications venues in 2024–2025 examines whose interests are prioritized in educational AI research. Key findings include that teachers are under-represented as research beneficiaries (appearing in only 33.3% of papers) despite being the most affected stakeholders, that real-world deployment of systems is rare (only 9.8% of papers), and that ethical engagement tends toward acknowledgement rather than substantive action. The authors identify a fundamental tension between private-sector incentives and the foundational needs of educational infrastructure, and offer concrete recommendations for more responsible EduNLP research practices.

Inducing Overthink: Hierarchical Genetic Algorithm-based DoS Attack on Black-Box Large Language Reasoning Models
Shuqiang Wang, Wei Cao, Jiaqi Weng et al.
arXiv · 2026-05-13
This paper demonstrates that Large Reasoning Models (LRMs) can be exploited through a denial-of-service attack that triggers 'overthinking' — excessively long and redundant reasoning traces — by systematically perturbing the logical structure of input problems. The authors develop a hierarchical genetic algorithm (HGA) that optimizes inputs to maximize response length and reflective markers, achieving up to a 26.1x increase in output length on the MATH benchmark across four state-of-the-art reasoning models. The attack is black-box and transfers from small proxy models to large commercial LRMs, meaning adversaries need minimal access to execute it. These findings expose a shared computational vulnerability in modern reasoning systems with direct implications for the reliability and security of AI-powered enterprise and quality-assurance applications.
