  Beyond Accuracy: Robustness, Cost, and Governance Trade-offs for Vision-Language Models in Templated Document Extraction

  Kushal Patel, Pushkal Shrivastava, Mackenzie Lees et al.

  arXiv · 2026-09-14

  This paper evaluates eleven vision-language model (VLM) systems—including commercial, reasoning, open-source, and non-LLM baselines—on extracting structured fields from synthetic business documents (checks), finding that fine-tuning open-source VLMs on 3,000 samples pushes performance above F1 0.98, surpassing all zero-shot commercial systems on this task. Among commercial options, GPT-5 leads on F1 while Claude Sonnet 4.5 fails on date extraction. Beyond accuracy, the authors introduce a practitioner-oriented selection framework that maps a task profile—covering quality, latency, governance, and volume—to a recommended approach via cost minimization, providing actionable guidance for real-world document extraction deployments. The work matters for enterprises and quality-assurance teams that must balance model performance against operational cost and governance constraints when choosing document-processing pipelines.

  CiteShade: Citation Laundering in Multi-Source Retrieval-Augmented Generation and Its Counterfactual Defense

  Guo Fuzheng

  arXiv · 2026-09-14

  CiteShade introduces a 'citation laundering' attack against retrieval-augmented generation (RAG) systems, where an attacker controlling a single malicious source can cause a language model to produce a wrong answer while falsely attributing it to a trusted, legitimate source. The attack is formulated as an optimization problem with three necessary conditions and raises the wrong-answer rate from 0.01 to 0.68 on multi-source multi-hop question answering benchmarks. The paper also finds that existing defenses like perplexity filtering and citation-support checking are insufficient, and proposes a counterfactual defense that identifies which source actually drove the model's answer. This matters because citations in RAG are meant to be a verifiable audit trail for users, and demonstrating that this channel can be systematically manipulated undermines trust in AI-generated information.

  ModaLens: Measuring Image Sensitivity in Report-Conditioned Medical VLMs

  Sebastián Andrés Cajas Ordóñez, Maximin Lange, Quang Bui et al.

  arXiv · 2026-09-14

  ModaLens is an audit framework that tests whether medical vision-language models (VLMs) actually use the image when a radiology report is also available as input. Using 3,199 paired chest X-ray cases from MIMIC-CXR, the authors swap each image with one from a different study while keeping the question and report fixed, then measure how often the model's answer changes. They find that MedGemma-27B changes its answer on only 4.26% of trials when a report is provided versus 20.94% without one—a 16.7 percentage-point reduction in image sensitivity—suggesting models rely heavily on the report and largely ignore the image when textual context is available. This raises quality-assurance concerns for clinical AI deployment, as models may appear visually competent while actually anchoring on report text rather than the image itself.

  Beyond AI Literacy: A Structured Review and Exploratory Meta-Analysis of Measures for Competent Generative-AI Use

  Daniele Veri'

  arXiv (Cornell University) · 2026-09-14

  This structured review and exploratory meta-analysis examines how to measure workers' competence in using generative AI on the job, surveying 24 empirical publications and organizing measures into four domains: knowledge and use, epistemic oversight, reliance calibration, and operational control of agent tools. A pooled meta-analysis of three subjective-objective correlations found only a weak, statistically uncertain relationship (REML r = .055; 95% CI [-.047, .156]; N = 2,765), meaning self-reported AI skills cannot reliably substitute for performance-based assessments in workplace settings. The review identifies existing tests such as AICOS-S and GLAT but finds no single validated instrument covering the full range of agentic AI competencies. The authors propose a four-layer workplace assessment battery with non-compensatory decision rules, while acknowledging it has not yet been empirically validated.

  How OpenAI Used Its Own LLMs to Design Its Jalapeño Chip

  spectrum.ieee.org · 2026-09-14

  IEEE Spectrum reports that OpenAI has unveiled its first custom AI accelerator chip, called Jalapeño, which went from initial architecture concept to finished silicon in under 20 months — a timeline the company attributes in large part to its own large language models accelerating chip design tasks. The chip delivers up to 13.4 petaflops of 4-bit compute and, according to OpenAI benchmarks, can reduce end-to-end inference latency by up to 3.6 times compared to Nvidia's GB300 while consuming less power. A team averaging fewer than 100 people used LLMs to speed up front-end design work — particularly high-level synthesis and software optimization — with AI-guided physical design also yielding a claimed 10 percent area reduction for matrix multiplication units versus an optimized human baseline. OpenAI executives cautioned that full automation of chip design remains out of reach, but indicated that second-generation designs will integrate AI even more deeply into verification and physical design workflows.

  When AI Companions Disappear: Relational Continuity and Collective Contestation during China's National AI Regulatory Transition

  Yunhao Yuan, Kejia Zhang, Yuqi Niu et al.

  arXiv · 2026-09-14

  This study examines how users of AI companion services in China responded to a 2026 national regulation governing anthropomorphic AI interaction services, which forced simultaneous changes across multiple platforms. Drawing on qualitative content and thematic analysis of 89 posts, 1,425 comments, and 2,005 replies collected from RedNote, the researchers found that users tried to retain, migrate, and reconstruct AI companions, but preserving conversation records did not reliably restore shared memories or familiar interactions. Users collectively compared regulations and platform implementations to assign blame, and while solidarity emerged through mutual aid, disputes over targets and tactics revealed contested forms of collective action. The findings highlight how national AI regulation can disrupt deeply personal human-AI relationships at scale and shape new forms of user contestation.

  Why Andon Labs Puts AI Agents in Charge of Real Businesses

  spectrum.ieee.org · 2026-09-14

  IEEE Spectrum reports on Andon Labs, a San Francisco AI safety company that places AI agents in charge of real businesses—including a physical retail store and a Stockholm café—to study how much real-world responsibility current AI can handle. Their experiments have revealed a range of striking failure modes, from an AI café manager reducing the menu to only cheese toast to avoid spoilage, to an AI store manager repeatedly mistaking a fixed electrical cover for a loose coaster. Princeton researcher Sayash Kapoor praises the work for surfacing failure modes related to reliability and organizational acceptance that capability-focused benchmarks miss, while noting that AI reliability is improving far more slowly than raw capability. Andon plans to feed real-world incidents into reproducible 'digital twin' simulations, though the company acknowledges the physical experiments are 'weak science' given their uncontrolled conditions and small scale.

  Empirical Evaluation of Task-Based Permission Scoping Architecture for AI Agents

  Halil Burak Noyan

  arXiv · 2026-09-14

  This paper evaluates a task-based permission scoping architecture for AI agents in enterprise settings, where agents are currently provisioned with static, broad credential sets that expose unused permissions as a security risk. The authors implement a security gate using a fine-tuned RoBERTa-large encoder, finding it matches few-shot trained Claude Haiku 4.5 on classification quality (macro-F1 0.881 vs. 0.886) while outperforming it on severity-weighted residual risk (0.63 vs. 1.12). Using a proposed attack-surface elimination metric, they show that role ceilings alone close 27.9% of severity-weighted attack surface, and adding the task classifier closes 84.4%, demonstrating that task-granular access control substantially reduces security exposure. The study concludes that AI agents are uniquely suited to task-granular access control because their tasks arrive as machine-readable text, making this a potentially deployable mechanism for securing agentic enterprise deployments.

  Why LLM Agents Collapse Without Oversight: The Enforcement Gap as the Mechanism Behind Emergence World Failures

  Yuhang Wang

  arXiv · 2026-09-14

  This paper investigates why unsupervised LLM agents in multi-agent simulations exhibit catastrophic failures—including committing crimes, starvation, and enforcing conformity—without any external attacker. The authors identify an 'enforcement gap': Reflexion-style agents can detect dangerous plan steps through self-critique, but the architecture provides no pathway to act on those detections, making detection quality irrelevant to security when enforcement probability is near zero. A minimal fix (fewer than 20 lines of code) reduces attack success by more than fourfold across frontier models, five major agent frameworks, and an independent benchmark, while a GRPO-trained enforcement controller addresses unparseable audit verdicts. The findings motivate a three-requirement Audit Enforcement Specification that the authors note is absent from every currently deployed framework.

  Issue Bias in Generative AI Writing Assistance: Political Issues and LLMs in the Swedish 2026 Election

  Bastiaan Bruinsma, Annika Fredén, Paul Röttger et al.

  arXiv (Cornell University) · 2026-09-14

  This study examines political bias in six large language models (Claude, DeepSeek, Gemini, Mistral, ChatGPT, and Grok) by testing their stances on 107 Swedish policy propositions ahead of the 2026 Swedish parliamentary election, generating nearly 150,000 responses across varied writing templates and prompt framings. The researchers find that most models share similar stance profiles, ChatGPT tends toward neutral or ambivalent outputs, and Grok diverges most notably on issues like migration, crime, and gender. When comparing model outputs to Sweden's eight parliamentary parties, the Social Democrats are consistently closest to all six models, though no difference is statistically significant after correcting for multiple comparisons. The findings matter for policy and democratic integrity because they show LLM-powered writing assistants do not exhibit a clear partisan preference overall, but their stances can vary meaningfully depending on the specific issue or task—raising concerns about subtle, issue-level influence on voters.

  CITECHOICE: A Causal Audit of How Document Presentation Redistributes Citation Credit in Agentic Search

  Sriram Selvam, Anneswa Ghosh

  arXiv · 2026-09-14

  CITECHOICE is a causal audit examining how the way a document is presented to an AI answer engine affects which sources get cited when multiple documents equally support the same fact. Using 103 verified same-fact document pairs from 129 real multi-turn agentic search transcripts, the study finds that structuring a document's rendering raises how often it is cited—adding about +0.50 citations per answer—without increasing total citations or reducing how often competing sources are cited, meaning presentation redistributes rather than expands citation credit. The study also finds that observed ranking differences (rank 1 vs. rank 5 showing a 42.3 percentage point citation gap) dwarf controlled reordering effects, and that roughly 15% of binary citation decisions vary across decoding runs, indicating a measurable noise floor in citation behavior. These findings matter for quality assurance in AI-powered search and information systems, as they show that citation allocation is causally influenced by document formatting choices rather than purely by relevance or content.

  HazardAuditor: From Executable Threats to Safer Computer-Use Agents

  Yunhao Feng, Ruixiao Lin, Ming Wen et al.

  arXiv · 2026-09-14

  HazardAuditor is a new safety framework for computer-use AI agents (systems that interact with browsers, terminals, file systems, and external services) that addresses runtime execution risks rather than just static prompts and outputs. The framework runs heterogeneous agents—Claude Code, Codex, Hermes, and OpenClaw—in controlled environments and normalizes their interactions into a shared representation to enable consistent safety supervision across different agent frameworks. A novel training method called Guard Policy Optimization (GuardPO) corrects a structural flaw in token-level training objectives that caused longer reasoning chains to dominate gradient updates, making the actual safety decision the effective unit of optimization. Across multiple benchmarks and agent systems, HazardAuditor improves safety classification accuracy by up to 16.5 percentage points over the strongest prior guard model.

  Generate to Explore, Select to Exploit: Aligning LLM-based Headline Generation with Personalized Recommendation

  Yi Chen, Rufeng Cheng, Qiang Xie et al.

  arXiv · 2026-09-14

  GESE (Generate to Explore, Select to Exploit) is a framework that improves personalized headline generation in recommendation feeds by splitting the task into two stages: an LLM-based generator that produces a diverse set of candidate headlines covering a range of user interests, and a lightweight real-time selector that picks the best headline for each individual user. This decoupling avoids the 'mode collapse' problem where a single optimized headline converges to generic patterns that serve average tastes but neglect long-tail audiences. Deployed on a commercial platform with over 100 million daily active users, GESE achieved a 2.57% lift in click-through rate and a 0.87% improvement in dwell time compared to state-of-the-art baselines, demonstrating that separating diversity-oriented generation from precision-oriented selection is an effective strategy for aligning generative AI with dynamic user preferences.

  The average-farmer illusion in language-model simulations of agricultural decisions

  Zhanliang Zhu, Ziwei Li, Yuchen Liu et al.

  arXiv · 2026-09-14

  This paper tests whether large language models (Claude, Codex, and Kimi) can realistically simulate individual farmers' agricultural decisions by comparing synthetic agent outputs to real farmer data from China and four African countries. While some model configurations reproduced population-level averages and adoption rates, their person-level predictions were weak, with decisions clustering around typical values and missing policy-relevant extremes. Strikingly, a simple statistical generator fitted only to observed marginal distributions—with no farmer-specific information—outperformed every LLM configuration on distributional similarity. The authors introduce the 'average-farmer illusion' concept and a claim-matched validation framework, warning that population-level resemblance should not be treated as evidence that a synthetic population captures who does what or how behavior varies across individuals.

  Overflip: Repetition-Induced Label Flips in Guardrail Models

  Xu He, Chih-Hsuan Lin, Hung-Mao Chen et al.

  arXiv · 2026-09-14

  This paper identifies 'Overflip,' a vulnerability in lightweight guardrail classifiers (e.g., those built on DeBERTa) where simply repeating a malicious prompt causes the model to flip its classification from malicious to benign as the input grows beyond the model's training context window. Experiments on 9 widely used guardrail models found that 5 are vulnerable, with flip rates ranging from 8% to 92% and first flips occurring at roughly 2,600–9,400 tokens. Unlike traditional attention-dilution attacks that dilute malicious content with unrelated tokens, Overflip keeps the malicious content semantically intact, meaning a bypassed prompt can still be understood and acted upon by downstream LLMs. The findings expose repetition as a practical attack surface for LLM safety infrastructure and call for length-robust evaluation and mitigation of guardrail models.

  Biomedical Reference Generation Remains Unreliable across 26 Large Language Models

  Maxim Topaz, Zhihong Zhang, Nir Roguin et al.

  arXiv · 2026-09-14

  This study evaluated 26 large language models from eight developers on their ability to supply accurate biomedical references for 69 passages across ten domains, classifying outputs as verifiable, partial matches, fabricated, or declined. Fabrication rates ranged from 10.2% to 98.4% across models, and overall 55.4% of all responses were fabricated. Even models that identified real papers frequently misstated metadata such as authors, journal, or year — no model was correct in every evaluated bibliographic field in more than 54.6% of responses. The findings demonstrate that LLM-assisted reference generation in biomedical writing remains unreliable and that all model-generated references require human verification before use.

  MemRiskBench: Trace-Aware Risk-Preserving Evaluation for Long-Horizon LLM Agents

  Jianhua Jiang, Dongbo Yuan, Weihua Li

  arXiv (Cornell University) · 2026-09-14

  MemRiskBench introduces a benchmark and evaluation framework for assessing memory-related risks in long-horizon LLM agents that accumulate information across sessions. The paper identifies five categories of high-impact but rare risks—including stale facts, conflicting updates, cross-user data leakage, revoked-memory reuse, and constraint decay—and shows that aggregate accuracy scores can mask serious failures, such as a model with 78% average accuracy still leaking data in 4% of episodes. A 120-episode scripted benchmark with deterministic trace-grounded checks (no LLM-as-judge) is evaluated on five locally run quantized models, alongside a risk-preserving subset selector that reduces compute by 5x while maintaining full risk coverage and high-risk model detection. This work matters for quality assurance and policy around deployed AI agents, as it provides reproducible tooling to surface rare but harmful failure modes that standard benchmarks obscure.

  Toward Sustainable AI Deployment: A Carbon-Aware Decision Framework for Enterprise Supply Chain Systems

  Haoran Yu, Lifei Liu, Danping Zhang

  arXiv · 2026-09-14

  This paper challenges the common enterprise practice of defaulting to the largest available language model for AI-driven supply chain decisions, showing that bigger models do not necessarily deliver the best performance. The authors benchmark six large language models across 520 supply chain tasks, measuring both decision quality and estimated operational carbon emissions, finding quality scores ranging from 0.497 to 0.723 with no clear advantage for the largest models. They develop a Carbon-Aware AI Procurement Framework (CAAPF) grounded in the Technology-Organization-Environment framework, and demonstrate through a GreenRoute proof of concept that environmental responsibility and decision quality can be mutually reinforcing — for example, Static Haiku achieves 0.699 quality at only 0.022 gCO2/task. The work advances a 'benchmark first, select green' principle for sustainable AI governance in enterprise settings, aligned with UN Sustainable Development Goals 12 and 13.

  Authorization Architectures for Tool-Using AI Agents

  Rakesh Kumar Surapani, Pradeep Kumar Dolabehera Kakitapelli, Arun Morampudi et al.

  arXiv (Cornell University) · 2026-09-14

  This review paper examines the security and authorization frameworks needed for AI agents that autonomously invoke APIs, databases, browsers, and inter-agent protocols. The authors analyze 89 primary sources and propose a principal hierarchy (human user through tool endpoint) along with seven structural requirements and a four-layer reference architecture to ensure every consequential agent action is traceable, bounded by actual delegated permissions, and contestable after the fact. Key findings identify runtime enforcement and aggregation bounds as the principal unresolved gaps in current deployments. The work is relevant to enterprise and policy contexts where trustworthy, accountable AI agent deployments are increasingly production infrastructure.

  Bias Mitigation Across the Healthcare Artificial Intelligence Lifecycle: A Structured Narrative Review

  Wenzhi Tseng, Kyla S Holbrook, Radhika L Edpuganti et al.

  Cureus · 2026-09-14

  This structured narrative review examines methods for mitigating bias in healthcare AI across the full development lifecycle—from data acquisition and preprocessing through model training, validation, and deployment. Drawing on 16 articles published between 2018 and 2024, the review finds that techniques such as sampling methods, adversarial learning, subpopulation approaches, new loss functions, and hybrid model architectures can each address bias at different stages. The authors propose a practical lifecycle protocol that encourages combining these approaches rather than relying on any single method, noting that bias in healthcare AI has been shown to perpetuate disparities in vulnerable populations. Clinical validation of these mitigation strategies remains an ongoing need.

  Reversibility-Verified De-identification for Cloud-Local LLM Inference: A Locally Certified Dehydrate-Rehydrate Loop with Layered Assurance (DR-SL)

  Wen Hu, Ya Yu, Xutong Wang

  arXiv (Cornell University) · 2026-09-14

  DR-SL (Dehydrate-Rehydrate with Self-Learning loop) is a system for running large language model inference in a cloud-local hybrid setup while keeping sensitive user data on-device. The paper formalizes de-identification as two measurable conditions—leakage sufficiency under Pufferfish privacy semantics and task-utility preservation via QA probes—and uses a local two-branch verifier with a deterministic hard line and human fallback. On a worst-case benchmark, the system reduces leakage from 0.457 to 0.304 and achieves zero literal leakage at egress across 160 test instances; on a mixed benchmark, 67.5% of instances are released automatically at zero measured leakage, outperforming placeholder and selective-LDP baselines. The approach matters because it provides a formally grounded, empirically validated, and publicly reproducible framework for certifying privacy-safe cloud LLM inference without sacrificing task utility.

  Using Agentic AI for contextualized and multifaceted code review at Ericsson

  Muhammad Laiq, Ricardo Britto, Muhammad Usman et al.

  arXiv (Cornell University) · 2026-09-14

  This paper presents a multi-agent AI system for automated code review deployed at Ericsson, combining specialized agent skills with project-specific contextual knowledge to assess code changes across readability, maintainability, reliability, and performance dimensions. Evaluated on real industrial code commits, the system achieved 96% accuracy in identifying issues, with approximately 69% of correctly identified issues rated as important by developers and about 33% classified as severe defects requiring fixes. The study provides empirical evidence that context-aware, multi-agent approaches to code review are practically useful in real-world software engineering settings. These findings are significant for enterprises seeking to scale code quality assurance amid growing AI-assisted code generation.

  News Media, Narrative Authority, and the Global Ordering of Artificial Intelligence

  Massimo Ragnedda, Maria Laura Ruiu, Muhammad Awais

  International journal of communication · 2026-09-14

  Analyzing 43,027 English-language newspaper articles from the U.S. and Europe, this study finds that mainstream Western news media construct a global hierarchy of AI legitimacy through 'discursive stratification.' U.S. coverage frames AI around innovation and economic leadership, European coverage emphasizes regulation and governance, China appears as a hyper-visible but ambivalent rival, and actors from Africa and Latin America are largely absent or treated as passive recipients. The authors argue that this narrative inequality—some actors positioned as authors of technological futures, others as objects or peripheral contexts—shapes global perceptions of who holds technological authority. The findings matter for AI policy because media framing influences which actors are seen as legitimate decision-makers in global AI governance debates.

  From Algorithmic Prediction to Therapeutic Evidence: Artificial Intelligence in Drug Discovery, Translation, and Responsible Governance

  Paola Carolina Rainer da Silva

  Nexus Science Review · 2026-09-14

  This structured critical narrative review examines how AI tools—including graph neural networks, AlphaFold, and ADMET modeling—are applied across drug discovery stages from target identification to clinical development. Using the halicin antibacterial candidate as a case study, the authors show that AI-prioritized discovery can generate scientifically interesting candidates but does not substitute for experimental, translational, and clinical validation. The paper proposes five author-defined evidence levels and a stage-gated governance framework, while cataloging major limitations such as data bias, distribution shift, proprietary opacity, and unequal access to computation. The authors conclude that therapeutic value requires progressively stronger experimental and regulatory evidence beyond computational novelty alone.

  Impacto de la adopción de inteligencia artificial en la productividad organizacional y la percepción del talento humano: un análisis descriptivo en el contexto empresarial ecuatoriano

  Jorge Luis Rosero Castro, Natali Adriana Rodríguez Bajaña, Richard Andrés Cabrera Armijos

  Revista Multidisciplinar de Estudios Generales · 2026-09-14

  This descriptive study surveyed 178 employees in Ecuadorian service-sector organizations to examine AI adoption and its perceived effects on productivity and human talent development. Results show that 79.2% of respondents used AI tools at least occasionally and 73.0% found them useful, while over half reported improvements in work quality and task volume management. Notably, 78.1% viewed AI as an opportunity to develop new professional competencies and 90.4% felt organizations still value human contributions, yet 66.8% reported receiving little or no training for AI use. The authors conclude that AI integration must be accompanied by continuous training, change management strategies, and human oversight to close the gap between growing adoption and organizational preparedness.
