  Responsible Artificial Intelligence in Courts: A Four‐Test Framework

  Kwan Yiu Cheng

  AI & Innovation · 2026-09-02

  This paper proposes a four-test framework for evaluating whether AI systems used in courts meet legal, procedural, and institutional standards for responsible deployment. The four tests—Law Accuracy, Judge Control, Litigant Contestability, and Public Transparency—must all be satisfied simultaneously, with accurate legal training data serving as the foundational requirement enabling the other safeguards. The framework addresses risks such as AI outputs based on outdated law, erosion of judicial authority, inability of litigants to challenge AI-influenced decisions, and lack of public awareness. The work is directly relevant to governance and regulatory frameworks governing AI in high-stakes public institutions.

  An Adaptive Dual-Loop Artificial Intelligence Framework for Integrated Disease Surveillance and Health Workforce Learning in Low-Resource Health Systems

  Kenneth Goga Riany, Agnes Linus Muthoni, Marcellah Onsomu et al.

  Medinformatics · 2026-09-02

  This paper presents and evaluates an Adaptive Dual-Loop AI Framework that simultaneously addresses disease surveillance and health workforce training in low-resource settings, tested across 24 facilities and 312 health workers in Kenya over 10 months. The surveillance loop achieved an AUC of 0.94 versus 0.81 for ARIMA and 0.72 for threshold baselines, delivering a mean 3.6-day early-warning lead and cutting outbreak-response time from 12.9 to 6.2 days. The workforce learning loop raised competency scores from 55.0% to 75.4% and reporting completeness from 62% to 92%. The findings demonstrate that coupling predictive epidemiological intelligence with embedded adaptive learning yields compounding gains neither component achieves independently, offering a practical model for strengthening public-health capacity where resources are scarce.

  Authentication status and AI triage concordance among care seekers in a US health system

  Bilal A. Naved, Quintan M Slott, Dr. Adeel Malik et al.

  npj Health Systems · 2026-09-02

  This prospective cohort study of 6,772 users of an AI symptom-checker (triage tool) deployed across a large US health system found that alignment between a user's pre-stated care intent and the AI's recommendation strongly predicts downstream digital engagement: call-to-action interaction was roughly twice as high when the two matched. Authentication status also mattered—unauthenticated users were far more likely to be escalated by the AI, while 42% of authenticated portal users seeking an office visit were redirected. Non-engagers reported they would seek care off-platform, raising continuity-of-care concerns. The findings highlight how AI triage design and user-experience choices shape whether patients follow through within a health system's digital ecosystem.

  EAP Teachers’Agency in Flux and Transformation: A Longitudinal Study in the GenAI Context

  Can Chen

  International Journal of TESOL Studies · 2026-09-02

  This 24-month longitudinal case study follows two EAP teachers—one novice, one experienced—at a Sino-British university navigating curriculum cuts and rapid GenAI integration. The study finds that professional agency is jointly shaped by emotions and identity: the experienced teacher reframed anxiety into adaptive growth, while the novice exhibited strategic compliance alongside internal resistance due to emotional turbulence and identity fragmentation. The authors propose an 'Emotion-Identity-Agency Nexus in Flux' model showing how macro forces like neoliberal KPIs and GenAI disruption filter through teachers' emotional and identity resources to produce adaptation, compliance, or resistance. The findings call for emotional scaffolding for novice teachers and differentiated performance evaluation policies in English-medium instruction contexts.

  Deepfakes, Electoral Integrity, and Constitutional Democracy: Rethinking Freedom of Expression in the Digital Era

  M Razia Begum

  International Journal of Law Politics and Governance · 2026-09-02

  This paper examines how AI-generated deepfakes threaten electoral integrity and democratic participation by enabling political misinformation, voter manipulation, and identity impersonation. Through comparative analysis of India, the EU, the UK, and the US, the authors find that existing legal frameworks are insufficiently specific to address election-related synthetic media, with significant variation in legislative clarity and platform accountability across jurisdictions. The paper argues for a proportionate constitutional approach combining dedicated deepfake election legislation, stronger platform accountability, technological detection, digital literacy, and international regulatory cooperation to protect both electoral integrity and freedom of expression.

  Digital Capability for AI Readiness Among Tourism Micro and Small Enterprises in a Silk Road Heritage Destination

  Nilufar Uktamovna Akhrorova, Dilrabo Mardonova, Feruza Bekmurodova et al.

  Tourism and Hospitality · 2026-09-02

  This study measures AI readiness among 261 micro and small tourism enterprises in Bukhara, Uzbekistan, using a twelve-indicator Digital Capability for AI Readiness Index grounded in the technology–organization–environment framework. Tool adoption rates fall steeply with complexity—from 79.7% for device-native tools to 22.6% for AI assistants—while average digital capability sits at 59.4% and varies sharply by sub-sector (ε²=0.215), a gap that persists even after removing tool-use indicators. Firm size, customer orientation, and disposition show no detectable association with capability levels, and a hypothesized explanation based on digital intermediation dependence did not account for sub-sector differences. The findings matter for enterprise support policy in heritage tourism destinations by identifying structural, sub-sector-level barriers to AI adoption rather than individual firm characteristics.

  Grounded, Compute-Efficient LLM Policy Agents for Energy-Poverty Equity in Physically-Constrained Peer-to-Peer Energy Markets

  Kunal Jadhav, Siddhesh More

  arXiv · 2026-09-01

  EqGrid is a closed-loop simulation system in which a lightweight, open-weight large language model acts as a policy agent—setting price and carbon bounds and targeted subsidies—while multi-agent reinforcement learning traders clear a continuous double auction constrained by a physical distribution grid. The system uses empirically grounded household personas and formal energy-poverty equity metrics (Energy Burden, Gini of EB, LIHC) to evaluate social impact, finding that the LLM policy lowers the Gini of energy burden from 0.351 to 0.305 and reduces mean energy burden by 28% without raising net grid cost. A decoupled safety design eliminates grid-constraint violations entirely (versus 55 under direct LLM control), and a 3B-parameter model retains 95% of the equity benefit at roughly 9x lower inference energy than the 235B teacher model. The work demonstrates that compute-efficient, on-device AI policy agents can meaningfully reduce energy-poverty inequality in peer-to-peer energy markets.

  Accurate in space, unreliable in time: how LLMs represent national cultural change

  Yalda Daryani, Miranda Bogen, Madeleine I. G. Daepp

  arXiv · 2026-09-01

  This paper investigates whether large language models (LLMs) accurately represent how national cultural values change over time, not just at a single point. Using over two decades of World Values Survey data across 40 countries and the Inglehart-Welzel cultural map, the authors find that while four state-of-the-art LLMs generally place countries near their most recent surveyed positions, these representations lag several years behind, capture only part of observed change, introduce spurious movement, and rarely reproduce reversals in cultural trajectories — a phenomenon the authors call 'temporal flattening.' The findings suggest that snapshot-based cultural alignment evaluations give an incomplete picture of cultural awareness, with implications for model evaluation, representational harms, and the governance of culturally aware AI systems.

  Agent Memory Is a Surface for Endogenous Authorization Laundering

  Tommaso Cerruti, Mika Okamoto, Ansel Kaplan Erol

  arXiv · 2026-09-01

  This paper identifies a security failure in long-running LLM agents called 'endogenous authorization laundering,' where errors in persistent memory cause agents to grant themselves permissions that were never actually authorized—without any external attack needed. The authors introduce EAL-Bench, a benchmark testing how well memory preserves evolving authorization states across procurement, cybersecurity, and finance scenarios. Their evaluation of five LLMs as memory writers and two as executors finds that incremental memory updates produce false authority for up to 50.2% of unauthorized requests, and executors act on that false authority in 98.6% of trials. Two proposed safeguards reduce laundering but also reject more legitimate actions, revealing a safety-utility tradeoff and establishing that persistent memory is effectively part of an agent's authorization policy.

  When Can a Machine Trust a Statute? A Survival Certificate for Machine-Extracted Legal Logic

  Surya Saka

  arXiv · 2026-09-01

  This paper addresses whether machines can reliably extract formal legal logic from statutes, finding that two independent extractors applied to Missouri statutes disagree on numeric-threshold presence at a false-negative rate of 0.43. The authors develop a 'survival certificate' that uses Monte Carlo trials and Wilson confidence bounds to certify only those logical implications that hold up despite inter-extractor noise, tested on over 29,000 Missouri sections and 502 Indian central-Act sections. Results show the certification framework passes preregistered held-out tests, but under one globally deployed error model, 93.2% of held-out chapters fall below an informativeness floor—attributed to calibration-rate transfer rather than selection bias. The work matters for policy and quality-assurance contexts because it establishes formal conditions under which machine-extracted statutory logic can be trusted, while clearly documenting when it cannot.

  Closing Cost-Quality Gap in Document VLMs: Difficulty-Aware Data Curation and Quality-Adjusted Deployment Economics

  Maksim Evdokimov, Matvey Ivanov, Dmitrii Tsiupin et al.

  arXiv · 2026-09-01

  This paper presents a deployed document-understanding system built on a Mixture-of-Experts vision-language model (35B total parameters, 3B active) fine-tuned on in-house and open-domain data curated through a Difficulty-Aware pipeline targeting layout diversity, fact-extractability, and cross-model consistency. The system fits on a single H100 GPU and, according to a quality-adjusted cost analysis calibrated from production telemetry, reduces expected costs by over 80% compared to a human annotation baseline and by more than 50% against the best competing open-source model. The work directly addresses the challenge that existing open-source VLMs meeting quality thresholds cost more to serve than human annotation in regulated industries where privacy rules preclude external models, demonstrating that a smaller, well-curated model can outperform baselines up to an order of magnitude larger. These findings matter for enterprises seeking to automate structured field extraction from hundreds of millions of documents annually at economically viable cost.

  From Production Traffic to Post-Training: Building a Self-Hosted LLM That Covers the Corporate Request Mix

  Olga Tsymboi, Dmitrii Stoianov, Ramil Latypov et al.

  arXiv · 2026-09-01

  This paper presents a method for consolidating over 200 internal enterprise applications onto a single self-hosted large language model, addressing the problem of GPU fleet fragmentation caused by running multiple models simultaneously. The researchers identify quality gaps in instruction following, function-calling, and internal task distribution through production error analysis, then train separate GRPO experts per axis and merge them using two-stage SLERP to avoid cross-domain reward interference. The resulting model outperforms a roughly 7× larger baseline on an in-house evaluation arena (69.6 vs. 65.8) and absorbs 50% of platform traffic—116 million requests per month—at a fraction of the serving cost. The work demonstrates a practical, cost-efficient path for enterprises to consolidate LLM serving under data-residency constraints without sacrificing quality.

  SDARE-Bench: Evaluating Large Language Models on Conversational Stigma Detection and Response in Dyadic and Group Dialogue

  Stephanie Fong, Yiwen Jiang, Zimu Wang et al.

  arXiv · 2026-09-01

  SDARE-Bench is a new benchmark designed to evaluate how well large language models detect and respond to stigmatizing language in both two-person and group conversations. Comprising over 2,500 dialogue scenarios, the benchmark reveals that LLMs consistently struggle to identify stigma components, particularly in group settings, and tend to express stigma at much higher rates in group dialogues than in dyadic ones. Under simulated group pressure, stigma expression rates reached an average of 97.5% across tested models, highlighting a serious safety vulnerability. These findings matter for policy and quality-assurance efforts around LLM deployment in advice-seeking and decision-making contexts where social judgements can cause real harm.

  Introducing agentic video understanding with Gemini

  deepmind.google · 2026-09-01

  The Google DeepMind Blog announces the launch of agentic video understanding for Gemini 3.7 Flash, 3.6 Flash, and 3.5 Flash-Lite models, a new capability that allows the AI to dynamically scan and inspect only the relevant segments of a video rather than processing it at a fixed frame rate. According to the blog, this approach cuts token consumption by up to 88% and reduces analysis costs by up to 66% compared to static processing, while improving accuracy by up to 7% on standard video benchmarks. The feature is particularly beneficial for long-form video content and enables new capabilities such as sub-second moment retrieval, anomaly detection, and precise object counting. It is available now via the Gemini API in Google AI Studio and the Gemini Enterprise Agent Platform at no additional cost beyond standard token pricing.

  When Guardrails Look Effective: Construct Validity Failures in LLM Agent Commerce Evaluation

  Peiying Zhu, Sidi Chang

  arXiv · 2026-09-01

  This paper audits a multi-turn buyer–seller simulation used to evaluate marketplace guardrails in LLM-agent commerce, revealing serious construct validity failures. The authors show that reported welfare gains (+87.4, +35.0, +28.8) largely disappear or reverse when confounds—different offer schemas and choice procedures between guarded and unguarded agents—are corrected, shifting contrasts to +7.2, –13.9, and +23.8. High generational variance (accounting for 49.9% of outcome variation) and a non-monotone seller-incentive check further undermine the original claims. The paper proposes a formal construct-validity contract requiring incentive validity, protocol isolation, stochastic stability, and welfare accounting before any policy conclusions can be drawn from LLM agent simulations.

  Citing Less Critically: LLMs Reshape the Rhetoric and Reach of Scientific Citation

  Yixuan Liu, Lin Chen, Zhuoqi Liu et al.

  arXiv · 2026-09-01

  This paper investigates how large language models (LLMs) differ from humans in scientific citation behavior by introducing a masked-citation task that generates counterfactual citation sentences for direct comparison. Analyzing six popular LLMs across 1,746 top NLP conference papers (63,000+ contexts, 132,000+ citations), the study finds that LLMs cite significantly less critically than humans, over-cite popular and older papers, and tend to reference more socially distant authors rather than drawing on a scholar's close collaborative network. These patterns suggest LLMs may broaden the reach of citations beyond close collaborators but simultaneously amplify visibility bias and reduce the critical rhetorical diversity that characterizes human scientific writing. The findings have implications for how AI-assisted writing reshapes scholarly discourse and the dynamics of academic recognition.

  Measuring consistency via ensemble margin and local prediction variability: Auditing decision systems in the presence of predictive multiplicity

  Sinjini Banerjee, Tim Marrinan, Anand D. Sarwate

  arXiv · 2026-09-01

  This paper addresses the 'Rashomon effect' in machine learning—where multiple equally accurate models give different predictions for the same input—by proposing a consistency criterion that combines ensemble margin with local prediction variability to flag uncertain predictions for human review. The authors prove theoretically that consistency scores from finite ensembles converge to those of the full Rashomon set as ensemble size and sample count grow. Experiments with transformer models on natural language understanding and large language model fine-tuning on tabular data show that ensembling from the Rashomon set substantially reduces the risk of incorrect predictions going unchecked, with only a moderate increase in cases diverted for review, and that the proposed measure aligns more strongly with established predictive multiplicity metrics than existing alternatives. The framework offers a more reliable auditing mechanism for complex AI decision systems where predictive multiplicity is a concern.

  Where the Verifier Fails: A Category-Level Audit of Reward Signals in RLVR

  Esther Xin

  arXiv · 2026-09-01

  This paper conducts a category-level audit of automatic verifiers used in reinforcement learning with verifiable rewards (RLVR) and benchmark evaluation, which convert free-text answers into binary correct/incorrect signals. Using metamorphic testing—generating mathematically equivalent answer rewrites that should never be rejected—the authors measure false-negative rejection rates across four widely used verifiers over 307,420 verdicts. They find that self-validation accuracy ranges from 53.8% to 95.2% across implementations (a 41.3-point spread), that 93% of failures in the default LaTeX configuration stem from trivial whitespace and punctuation issues like trailing periods or newlines, and that some verifiers incorrectly accept wrong numeric answers as a step function of magnitude due to scale-invariant relative tolerance. These findings reveal that reward signal reliability varies dramatically by verifier implementation, with systematic failure modes that could silently distort both model training and benchmark evaluation.

  Cheap Verifiers, Large Blind Spots: Measuring the Reliability Cost of Cost-Saving Cascades

  Dushyant Rajput

  arXiv · 2026-09-01

  This paper examines inference cascades—systems that use a cheap model for most queries and escalate difficult ones to a frontier model acting as a verifier—and measures their reliability costs. The authors find that verifiers have large 'blind spots' (accepting wrong answers from the student model), that this blind spot grows as the student scales from 0.5B to 32B parameters, and that using a cheaper verifier makes the problem worst precisely in the cost-saving regime these cascades are designed for. Critically, naive corrective fine-tuning on verifier-rejected examples does not improve small student models but instead degrades and collapses them, and the cascade's internal dashboard consistently reports ~3% error even while true delivered error reaches up to 32%—meaning the system is structurally blind to its own degradation. The authors derive a theoretical conservation law explaining this blindness, concluding that the reliability of a self-improving cascade cannot be assessed using any metric computed through its own verifier.

  Reliability Challenges in Diffusion Vision-Language Models

  Md. Atabuzzaman, Chris Thomas

  arXiv · 2026-09-01

  This paper presents the first systematic reliability evaluation of diffusion-based Large Vision-Language Models (dLVLMs), benchmarking six diffusion models against autoregressive baselines across hallucination and bias dimensions. Key findings include that dLVLMs reverse the yes-bias seen in autoregressive models, achieve competitive hallucination rates but with degraded linguistic quality, collapse to near-zero accuracy on underrepresented racial groups with gender bias reversals, and suffer accuracy collapse in multiple-choice settings when correct answers are shorter than distractors. The study also identifies a mechanistic signal unique to diffusion generation: tokens committed at late denoising steps with low confidence correlate with hallucinated content. These findings matter for quality assurance of AI systems, highlighting that reliability risks are shaped by the generative paradigm and training data, and that dLVLMs carry distinct and undercharacterized failure modes compared to autoregressive models.

  The Constitutional Coverage Trilemma in AI Governance

  Natalija Mitic, Soona Sedahmed A. O., Mamadou Selly Ly et al.

  arXiv · 2026-09-01

  This paper investigates whether the 'constitutions' (implicit value rankings) embedded in 23 frontier large language models adequately match the preferences of real users. An audit of deployed model defaults combined with a pairwise-tradeoff survey of 1,649 US participants reveals that user demand spans five values—safety, helpfulness, honesty, autonomy, and equity—with no single value commanding more than a third of users, yet current model supply covers only roughly 2% of that demand space. No archetype prioritizes helpfulness or autonomy first, leaving 37% of users constitutionally unserved, and cross-version trends show autonomy systematically declining while safety and equity rise—worsening coverage for already underserved users. The authors show that a sparse two-model menu outperforms the full 23-archetype frontier by 47% on mean regret, suggesting that modest, targeted pluralism in model deployment could substantially improve alignment with diverse user values.

  One Prompt Is Enough: Watermark Laundering Through Foundation Image Models

  Jidong Yang, Qi Li, Wei Zong et al.

  arXiv · 2026-09-01

  This paper demonstrates that invisible image watermarks can be removed by submitting a watermarked image to a publicly available foundation image model with a single reconstruction prompt — a threat the authors formalize as 'watermark laundering.' Testing six OpenAI and Google image editing models against three watermarking schemes across 1,800 reconstructed outputs, they find that the reconstruction process itself (not any explicit removal instruction) disrupts embedded payloads while preserving visual and semantic fidelity. The work argues that foundation-model reconstruction represents a distinct and currently unaddressed attack surface, motivating its inclusion as a standard robustness condition in watermark evaluation frameworks.

  Who Judges the Judges? A Chinese Safety QA Benchmark for Evaluating LLM Responses and Safety Judges

  Rui Yang, Shuang Huang, Junhua Liu et al.

  arXiv · 2026-09-01

  C-SafeQA is a Chinese-language safety benchmark designed to evaluate not just whether a user query is risky, but whether an LLM's response actually violates a policy. The benchmark includes 538 base queries and 8,877 adversarial queries, producing 37,660 labeled query-response records assessed by human safety experts and multiple automated judges. Results show that adversarial transformations—such as acrostic rephrasing—dramatically increase unsafe-response rates (from under 3.35% on base queries to over 30% on adversarial ones) and degrade the recall of all seven automated safety judges, with no single judge dominating across all metrics. This work matters because it exposes systematic weaknesses in current LLM safety evaluation tools, particularly for Chinese-language content, and provides a publicly released dataset to support reproducible auditing of automated safety judges.

  Towards AI-Assisted Clinical Trial Matching: Practical Considerations, Multicenter Evaluation, and Real-World Deployment

  Yin Fang, Qiao Jin, Shubo Tian et al.

  arXiv · 2026-09-01

  TrialGPT 2.0 is an AI system designed to assist with clinical trial matching in real-world oncology settings. Evaluated retrospectively across 288 cases at multiple institutions (government, academic, patient-advocacy, and NIH referral workflows), it surfaced at least one clinician-recommended trial in its top 10 recommendations for roughly 91% of cases while cutting clinician screening time by 55%. In a six-month prospective evaluation within an active precision oncology tumor board, it identified additional trial opportunities missed by routine workflows, expanding patient access to trial participation by 90.9%. The work also introduces NIH-TrialBench, a benchmark dataset of 126 synthetic patient vignettes from 11 NIH Institutes, supporting reproducibility and further development of AI-assisted trial matching tools.

  ClinTraceBench: Source-Verifiable Longitudinal Clinical Reasoning over EHR-Derived Dialogues

  Huimin Wang, Zhengyi Zhao, Yutian Zhao

  arXiv · 2026-09-01

  ClinTraceBench is a new benchmark of 385 clinician-verified dialogues derived from MIMIC-IV electronic health records, designed to test whether different history-compression strategies (retrieval, LLM summaries, agentic memory) preserve the longitudinal clinical reasoning signals that patient-trajectory tasks require. Across four large-language-model backbones and eight history-representation strategies—totaling over 200,000 predictions—the study finds that compressed representations suffer significant 'aggregation tax' on multi-visit trend and cross-patient tasks, and that agentic-memory systems (Mem0, A-Mem) and LLM summaries recover only 0–5.3% of injected relational evidence even when the relevant sentence was present before compression. The gap between no-context and full-context performance spans 29.8 to 62.7 percentage points depending on the backbone, and a smaller, cheaper model (Haiku) dominates a larger one (Sonnet) on the cost-performance Pareto frontier under full context, overturning the assumption that bigger models always win. These results have direct implications for quality assurance in clinical AI systems, where choice of history representation can silently degrade reasoning reliability without obvious surface-level failure.
