Lossless but Not Free: An Empirical Anatomy of Speculative Decoding on Consumer Hardware
Param Chordiya
arXiv · 2026-07-19
This paper presents an empirical study of speculative decoding—a technique that uses a small draft model to propose tokens in bulk, which a larger target model then verifies in one batched pass, preserving the target's output distribution exactly. Tested across five draft/target configurations on a consumer Apple-silicon laptop, the best setup achieves a 1.61× wall-clock speedup, but three of five configurations actually slow things down due to hardware-specific failures such as a quantized Metal backend executing verification serially rather than in parallel. The study rigorously confirms distribution equivalence between standard and speculative decoding via statistical testing, and highlights that the technique's benefits depend critically on genuine batch-parallelism during verification and a real latency gap between draft and target models. The findings are relevant to enterprise and workforce contexts where deploying large language models efficiently on consumer hardware is a practical concern.

Between Safe Boundaries: Exploiting Temporal Consistency for Jailbreaking Text-To-Video Generation Models
Xingkai Peng, Jun Jiang, Jiayang Liu et al.
arXiv · 2026-07-19
This paper presents BSB, a jailbreak framework targeting text-to-video (T2V) AI generation models by exploiting temporal consistency—the way video frames must flow coherently over time. Instead of adapting text-to-image attack methods, BSB encodes harmful content as a transition between two individually innocuous 'boundary states,' causing unsafe intermediate frames to emerge during video generation. The framework uses Monte Carlo Tree Search in a textual proxy space to efficiently explore attack candidates without excessive video queries, and is evaluated against commercial models including Veo 3.1, Sora 2, Seedance, and Kling v1, achieving an average 18.6% relative gain in attack success rate over the strongest existing baseline. The findings highlight temporal consistency as a critical and underexplored vulnerability in T2V systems, with significant implications for AI safety policy and quality assurance in deployed generative video models.

Safety That Does Not Transfer: Cross-Lingual Clinical Correctness Drift in Deployable Medical Language Models
Anthonio Oladimeji Gabriel, Dimeji Olawuyi, Toba Ajayi et al.
arXiv · 2026-07-19
This study investigates whether clinical safety established in English for large language models transfers to Hausa, focusing on locally deployable small models (4–9 billion parameters) used in low-resource health settings in northern Nigeria. Matched English-Hausa question pairs covering malaria, sickle cell disease, and tuberculosis were evaluated across six models and scored against Nigerian national treatment guidelines by two fluent Hausa speakers. Among locally deployable models, mean clinical correctness dropped dramatically from 1.57 in English to -0.03 in Hausa (on a scale where 2 is correct and -1 is actively harmful), while a frontier model remained competent in both languages. The authors conclude that this safety gap is a property of the deployable model tier rather than the language or clinical content itself, raising urgent concerns for AI deployment in multilingual, resource-constrained healthcare settings.

A Large-Scale Measurement of AI Bill of Materials Completeness in Hugging Face Models
Md Erfan, Ahmed Ryan, Md Rayhanur Rahman
arXiv (Cornell University) · 2026-07-19
This paper empirically examines the completeness of AI Bills of Materials (AIBOMs) generated from approximately 97,500 Hugging Face model repositories, assessing how well these repositories provide machine-readable documentation on model provenance, licenses, datasets, limitations, and external references. The study finds that while required structural fields are fully represented in generated AIBOMs, AI-specific documentation—including model-card details, responsible-use information, environmental impact, and meaningful descriptions—remains weakly represented or absent. These gaps create transparency and governance risks across the AI supply chain, highlighting the need for improved model-card practices, repository-level traceability, and automated AIBOM validation.

AI_LectureNote: A Retrospective Pilot Study of a Post-ASR Workflow for English-Script Rendering and Semantic Drift in Korean-English Medical Lectures
Kyeongeon Lee, Donghoon Chang, Seungryeol Baek et al.
arXiv · 2026-07-19
This paper presents AI_LectureNote, a post-processing workflow that rewrites automatic speech recognition (ASR) output from Korean-English medical lectures into readable study transcripts by restoring Latin-script medical terms instead of Korean phonetic transliterations. In a retrospective pilot across four lectures and five conditions, the workflow raised English-script rendering rates substantially (e.g., from 0.39 to 0.71 on one ASR path), but improved surface rendering did not guarantee semantic faithfulness—post-processed outputs still showed semantic drift in roughly 34–36 of 282 reference sentences and polarity failures in 11–13 of 101 polarity-cue rows. The study identifies distinct failure patterns between surface accuracy and medical-meaning preservation, arguing these dimensions must be evaluated separately. The findings matter for quality assurance in AI-assisted medical education tools, where surface correctness can mask clinically significant errors in meaning.

Robust Summarization of Doctor-Patient Conversations: TalTech Systems for the Beyond Transcription Challenge
Aivo Olev, Tanel Alumäe
arXiv · 2026-07-19
This paper presents TalTech's winning systems for the Beyond Transcription Challenge, which requires generating clinical SOAP notes directly from doctor-patient audio recordings without intermediate transcription. The team adapted Voxtral Mini and Voxtral Small speech language models using LoRA supervised fine-tuning followed by DAPO reinforcement learning, with Open Medical Concept F1 as the reward signal. Their systems ranked first in both lightweight and heavyweight tracks, and an independent LLM-as-a-judge evaluation found they had the lowest hallucination rate among all submissions. The work also shows that fine-tuning on text transcripts can transfer effectively to speech input, improving robustness on out-of-domain real-world recordings.

Specifying the Delegated-Autonomy Boundary: Requirements Engineering for Agentic AI
Chetan Arora, Andreas Vogelsang, Abbi Sharma
arXiv (Cornell University) · 2026-07-19
This paper addresses a gap in requirements engineering for agentic AI systems—those that plan, maintain state, and act autonomously in external environments. The authors argue that current practices embed critical autonomy decisions inside prompts and runtime policies rather than treating them as explicit requirements-level commitments. They propose two artifacts: an Agency Justification Record (AJR) to evaluate whether an agent is warranted over simpler alternatives, and an Agentic Delegation Policy (ADP) that formally specifies purpose, authority, information, coordination, assurance, and evolution with a graduated authority model. The framework is illustrated through two contrasting examples—a safety-critical hospital discharge coordination agent and an automated code review agent—highlighting its relevance for safe and effective deployment of agentic AI.

Toward Anthropomorphic Dialogue: A Closed-Loop Framework for Human-Like Chat Generation, Evaluation, and Preference Alignment
Wentao Liu, Siyu Song, Xi Chen et al.
arXiv · 2026-07-19
AnthroDial is a closed-loop framework for generating and evaluating human-like private chat that preserves persona, memory, timing, and multi-turn coherence. The system combines a role-conditioned dialogue runtime, an executable benchmark across ten behavioral dimensions, and a post-training pipeline using supervised fine-tuning and reinforcement learning with a cognitively-informed reward signal. Evaluated across 16 systems and 100 role-conditioned cases per model, the best trained model (Qwen3.6-27B-SFT+RL) achieves 39.00% strict accuracy versus 32.00% for the strongest untrained baseline, and a 9B model improves from 0.00% to 18.37% strict accuracy after training. The results demonstrate that tightly coupling generation, evaluation, and reward shaping around shared behavioral dimensions meaningfully advances anthropomorphic dialogue quality.

PocketPPD: Screening for Postpartum Depression Risk Using Passive Smartphone Sensing
Jia Tang, Helinyi Peng, Akihito Taya et al.
arXiv · 2026-07-19
PocketPPD is a passive smartphone sensing system designed to screen new mothers for postpartum depression (PPD) risk without requiring constant active input from users. Using multi-modal sensor data collected over a four-week feasibility study with 61 postpartum women, a passive sensing-only model achieved an AUC of 0.75, while a combined model integrating passive sensing and self-report features reached an AUC of 0.83. The study identifies morning and late-night routine volatility as top digital biomarkers, moderated by factors like infant developmental stage and employment status. This work supports the feasibility of continuous, low-burden perinatal mental health monitoring as an alternative to traditional screening questionnaires.

How Jailbreak Attacks Inform Safety Alignment: A Defender-Centric, Shapley-Based Evaluation of Jailbreak Contributions
Yukai Zhou, Feiyang Lu, Xiaokai Mao et al.
arXiv · 2026-07-19
This paper challenges the standard practice of evaluating jailbreak attacks on large language models solely by attack success rate (ASR), arguing that a high ASR does not necessarily translate into useful data for improving model safety. The authors propose a defender-centric framework called A-MESS, which uses Shapley values (AttackSHAP) to attribute how much each jailbreak attack contributes to downstream safety improvements when used as red-teaming training data. Their experiments show that ASR rankings are weakly correlated with actual safety utility, and that directly optimizing compact subsets of attacks via their framework yields stronger safety gains than attacker-centric selection methods. This work has implications for how organizations design safety alignment pipelines and allocate red-teaming resources for LLMs.

SlotGuard: Stop Oversharing Private Local Context in LLM Agent Transcri
Haocheng Xia, Yongjoo Park
arXiv · 2026-07-19
SlotGuard is a privacy-preserving system designed to prevent LLM agents from leaking sensitive local context—such as file paths, emails, and API keys—when agent observations are appended to provider-bound transcripts. The system rewrites structural bindings as typed slots, replaces secrets with format-preserving synthetic values, and links cross-turn references via a session graph, restoring raw values only inside a trusted runtime. On controlled benchmarks, SlotGuard removes all 20,814 annotated sensitive characters and reduces credential leakage to 0.0% across 852 planted values, while maintaining task success rates close to those of raw transcripts and completing rewrites in a median of 14.424 microseconds per turn. This matters for enterprise and policy contexts because it demonstrates a practical, low-overhead method to limit data exposure when deploying LLM agents that interact with local systems.

Fenced Citation-Context Retrieval for Case Law: Temporal Leakage and Degree Control Across Two Jurisdictions
Yao Liu, Tien-Ping Tan, Zhilan Liu
arXiv · 2026-07-19
This paper addresses a methodological flaw in prior case retrieval (PCR) systems that use citation context—text describing how later cases reference earlier ones—as a relevance signal. The authors show that existing evaluations allow 'temporal leakage,' crediting retrievers for citations made after a query case was filed, which inflates reported performance gains. They introduce a zero-training, temporally fenced retriever that restricts citation context to pre-query citations only, and demonstrate on two jurisdictions (U.S. federal CLERC and European ECtHR-PCR datasets) that this fencing reveals up to 14.9% of reported citation-context gains are attributable to future citations not available at query time. The findings establish that citation-context retrieval must be both temporally fenced and degree-controlled for its gains to be meaningfully interpreted, with direct implications for the reliability of legal AI retrieval benchmarks.

Teach it to stop, not just to click
Barada Sahu, Shivesh Pandey
arXiv · 2026-07-19
This paper investigates the reliability of benchmarking for large-scale computer-use AI agents (CUAs), specifically a 35B model improved via a verifier-guided repair process across five evaluation environments. Using variance-components analysis, the authors show that single-run evaluations—the current norm in this field—are dominated by data-draw and run-to-run nondeterminism rather than training-seed effects, and that the run-to-run distribution can be bimodal, meaning a single reported result has roughly a 30% chance of reflecting a failure mode. They find that repair works reliably only for tightly constrained actions (e.g., a fixed 'done' token at 0.97 success rate) but degrades for open-ended corrections like spatial clicks or generative field-fills, and that task-level gains appear only when the repaired action is the sole remaining blocker. The paper argues that single-run reporting in agentic AI benchmarks is systematically misleading and releases a library (cua_reliability) to support routine multi-seed evaluation practices.

Auto Research for Materials: Auditable AI-Scientist Workflows with Held-Out Transfer
Jingjie Ning, Xiaochuan Li, Shanshan Zhong et al.
arXiv · 2026-07-19
This paper develops an auditable AI-scientist workflow for materials property prediction that rigorously tests whether AI-driven modelling improvements genuinely generalize rather than merely overfitting to the development loop. Across 701 evaluated changes spanning ten Matbench endpoints, the authors freeze selected code and evaluate it once on a held-out dataset never seen during search, finding that nine of ten chosen interventions remain the best single tested change. Key validated gains include 17.4% held-out MAE reduction for band gap, 18.6% for steel strength, and a 26.3% mean improvement when separately discovered feature and model changes are combined. The work establishes an evaluation design for executable AI discoveries that can be audited, reused, and combined beyond the feedback loop, with direct implications for how AI research agents should be assessed in scientific and enterprise settings.

Otap:Structure-Aware Optimal Transport for Evaluating Planning and Execution in Agent Trajectories
Babak Barazandeh, Subhabrata Majumdar, George Michailidis
arXiv · 2026-07-19
This paper introduces OTAP (Optimal Transport for Agentic Planning), a new metric for evaluating the trajectories of large language model agents that interleave planning, tool calls, and intermediate results. Rather than reducing evaluation to a binary success flag or exact reference matching, OTAP frames trajectory evaluation as a distance between the agent's execution graph and a set of valid solution graphs, instantiated via an unbalanced fused Gromov-Wasserstein transport problem over attributed dependency graphs. The metric is provably invariant to dependency-preserving reorderings, handles missing or hallucinated steps, and accommodates variation in plan granularity. On controlled perturbations and three public benchmarks, OTAP better separates valid from invalid trajectories than semantics-only metrics, making it a more principled tool for assessing agent reliability and plan quality.

ALLUDE: A Unified Evaluation System for Configurable Attacks in Differentiable Environments
Mansi Phute, Alexander Greenhalgh, Matthew Hull et al.
arXiv · 2026-07-19
ALLUDE is a unified, open-source evaluation system that assesses adversarial attacks against vision-based object detectors within differentiable rendering environments across diverse, configurable conditions. By sampling from 5,400 configurations spanning multiple scene-object pairs, weather conditions, optimizers, camera trajectories, and detection models, the system reveals that existing attacks (CAMOU, RAUCA, FCA) degrade in success rate across all tested conditions, exposing evaluation gaps in prior work. The framework bridges simulation and differentiable rendering to enable end-to-end optimization and more rigorous benchmarking of adversarial robustness, and runs on both Linux and Windows. This matters for quality assurance of AI vision systems deployed in real-world conditions, where limited evaluation environments can mask significant performance failures.

A Systematic Evaluation of Traditional Privacy Policy Analysis Tools Against LLMs
Madhav Aryal, Sudipa Saha, Kaushal Kafle et al.
arXiv (Cornell University) · 2026-07-19
This paper systematically evaluates whether large language models (LLMs) can replace specialized privacy policy analysis tools across three major functionalities: contradiction detection, regulatory compliance analysis, and privacy policy summarization. Testing GPT and Gemini models against six representative tools on ten privacy policies, the authors find that LLMs consistently match or exceed specialized tools, achieving up to 91.4% precision and 70.8% recall for labeling third-party sharing entities compared to the OPP-115 dataset. The findings suggest that off-the-shelf LLMs can broadly perform privacy policy and regulatory compliance analysis without requiring domain-specific training or specialized tools, significantly lowering the barrier to compliance work.

Bridging the Information Gap: Semantic Densification and Hindsight Distillation for Cold-Start Prediction
Hao Duong Le, Yifei Gao, Huan Li et al.
arXiv · 2026-07-19
This paper presents SemRaD, a framework for predicting new-user lifetime value (LTV) and conversion rate (CVR) on e-commerce platforms where users have sparse interaction histories — the 'cold-start' problem. SemRaD combines structured semantic reasoning from large language models with a teacher-student distillation approach that handles variability in how much privileged information is available per user. On a large-scale industrial dataset and a four-week online A/B test at Keeta, SemRaD delivered measurable gains of +1.9% LTV and +1.0% CVR over a production-grade baseline, and matched the production system's LTV performance using only 9% of the training data. This matters for enterprise recommendation and marketing systems, where better cold-start prediction can directly improve customer acquisition decisions and resource allocation.

Who Will Become the Next Senior? How Generative AI Erodes the Development Pathway in Software Engineering
Sumin Yu, Taesup Moon
arXiv (Cornell University) · 2026-07-19
This qualitative study examines how Generative AI is disrupting the career development pipeline for junior software engineers, based on 14 semi-structured interviews with early-career and senior engineers in South Korea. The researchers identify a pattern they call 'Absorption,' where entry-level tasks are redirected into senior-AI workflows, depriving juniors of the formative productive struggle that traditionally builds expertise. Three downstream consequences are documented: loss of developmental challenge for juniors, normalization of GenAI use in university classrooms that structurally reproduces this loss, and a perceptual asymmetry between seniors and juniors that prevents self-correction. The authors argue that preserving the pathway to senior engineering roles will require deliberate institutional design spanning classrooms, workplaces, and junior evaluation criteria.

When LLMs Over-Answer: Measuring and Mitigating Quality Issues in LLM-Based Hardware Description Language Question Answering
Ziteng Hu, Jiachi Chen, Wenhao Lv et al.
arXiv · 2026-07-19
This paper investigates quality issues in LLM-generated answers to hardware description language (HDL) questions, finding that LLMs tend to 'over-answer' by burying correct content under redundant alternatives (65.7% of responses) and verbose padding (69.1%), while nearly half (49.0%) fail to fully align with expert answers. The authors built a dataset of 6,246 HDL Q&A posts from Stack Overflow and conducted a user study with 19 HDL engineers to benchmark LLM responses against human expert answers. To address these issues, they propose a multi-agent framework that improves core-answer quality scores from 3.71 to 4.67 and non-core content quality from 3.72 to 4.23 on a five-point scale across four mainstream LLMs. The findings matter because imprecise or verbose HDL answers can propagate into hardware design errors such as timing violations or non-synthesizable logic, making answer quality especially consequential for engineering practice.

Where Does Agent Reliability Come From? A Cross-Benchmark Decomposition of Verification Loops, Specialist Models, and Scaffolding in a Production Enterprise Agent
Arunabh Dastidar
arXiv · 2026-07-19
This paper investigates where reliability gains come from in a production enterprise AI agent (Leni) by evaluating it across three public benchmarks targeting distinct failure modes: silent computation errors, premise confabulation, and cascade errors in long tool chains. The system outperforms its frontier base model by roughly +11 points on SpreadsheetBench, +7–10 points on BullshitBench, and ~+15 points on GAIA validation, with the full system reaching 75.2% pass@1 on GAIA. Crucially, the paper's decomposition finds that most of the performance uplift comes from scaffolding, routing, and specialist models rather than from verification loops alone, whose isolated contribution is small (+1.5 points) but concentrated on otherwise-failing tasks at the top of the score distribution. These findings matter for enterprise AI deployment, showing that architectural choices around specialist post-trained models and task routing are the primary drivers of agent reliability, with implications for how production systems should be designed and quality-assured.

Artificial Intelligence and Academic Integrity in Virtual Higher Education: A Descriptive-Comparative Study of Student and Faculty Perceptions in Ecuador
Héctor Carvajal Romero, Fernanda Tusa, Rosemary Samaniego et al.
Trends in Higher Education · 2026-07-19
This survey-based study compared perceptions of generative AI use and academic integrity between 1,660 students and 34 faculty at the Technical University of Machala, Ecuador during 2024. Students tended to view AI primarily as a useful academic support tool, while faculty were more concerned with authorship, evidence authenticity, and assessment security. Both groups identified limitations in current virtual assessment practices. The authors propose a governance model emphasizing transparent disclosure policies, authentic assessment design, faculty development, student AI literacy, and proportional proctoring rather than blanket prohibition or permissive ambiguity.

AI governance and employee well-being in digital workplaces: A systematic literature review
Yulianto, Udin Saryono
Digital Theory Culture & Society · 2026-07-19
This systematic literature review synthesizes 44 peer-reviewed studies (2015–2026) on how AI-mediated governance in digital workplaces affects employee well-being. The review finds that while AI-driven systems improve organizational performance, they also contribute to technostress, burnout, AI anxiety, identity threats, and reduced worker autonomy, with key ethical concerns including algorithmic bias, opacity, and discrimination. The authors propose an integrative conceptual framework linking algorithmic workplace practices, ethical challenges, and employee well-being, moderated by factors such as AI transparency, organizational support, and ethical leadership. The paper concludes with a practical framework for implementing human-centered AI governance in digital workplaces.

Algorithmic Enforcement and the Administrative State: Due Process and Accountability in the EU and the United States
Edward Koellner
Zenodo (CERN European Organization for Nuclear Research) · 2026-07-19
This article examines how public agencies in the EU and the United States are delegating enforcement decisions, risk assessments, and eligibility determinations to AI and algorithmic systems, and what that means for due process and administrative accountability. The authors argue that discretion once held by frontline caseworkers has shifted upstream into technical choices—training data, feature weights, decision thresholds—that effectively become de facto policy without appearing in any traceable administrative record. The paper contrasts Europe's preventive, rights-centered approach (GDPR Article 22, EU AI Act impact assessments, deployment registries) with the U.S.'s reactive, litigation-driven model under the Administrative Procedure Act, finding both systems ultimately converge on the need for auditable rationales, substantive human oversight, and ongoing monitoring for model drift. The authors propose a hybrid regulatory framework that combines Europe's proactive transparency tools with America's robust contestation rights and court-ordered discovery, reinforced through procurement requirements and judicial insistence on legible records.
