PolyJarvis is an LLM‑orchestrated platform that automates all‑atom molecular dynamics simulations of amorphous homopolymers. It generates validated run plans, constructs systems with Enhanced Monte Carlo, runs dynamics in LAMMPS, and extracts target properties, all while handling failures within a fixed decision budget. Validation on seven polymers—PE, aPS, sPVC, PLLA, PEG, PEEK, and PSU—showed that 13 of 19 property comparisons met experimental acceptance criteria, though some PCFF‑based systems exhibited density and glass‑transition discrepancies.

Large Language Models often fail to respect instruction hierarchies in multi-turn settings, sometimes following lower-priority directives over higher ones. The authors formalize this failure using a Jensen‑Shannon Divergence framework and introduce IHDec, a contrastive decoding method that detects hierarchy violations at the token level and suppresses subordinate role influence without any fine‑tuning. Experiments show IHDec outperforms training‑based baselines, maintains overall response quality, improves safety against adversarial prompts, and scales well with larger models.

SCOUT is a frozen‑encoder approach for sim‑to‑real text‑based person retrieval that predicts cross‑modal embeddings instead of fine‑tuning cross‑encoders. It uses a trainable predictor to map patch tokens from a frozen video encoder (V‑JEPA) into the embedding space of a frozen text encoder (EmbeddingGemma), guided by a bidirectional InfoNCE objective. The method achieves state‑of‑the‑art results on the AI City Challenge 2026 Track 4, with a full retrieve‑fuse‑rerank pipeline reaching 84.25 mAP@10 and a single frozen model alone scoring 60.63, while training costs are modest (≈95 GPU‑hours).

MM-Future is a world-action model for autonomous driving that generates multiple paired scene-action hypotheses and captures bidirectional interaction within each pair. It initializes each hypothesis from a structured action prior and an independent future scene source, then co-evolves them using a modality-aware diffusion Transformer. The model compresses multi-view video into planning-oriented MM-Tokens and uses a future-conditioned proposal scorer to rank trajectory candidates, achieving strong performance on NAVSIM and HUGSIM benchmarks.

CoMa introduces a contextual massing generation framework that leverages vision‑language models to produce building massings that fit a target parcel and align with surrounding urban morphology. The study uses a dataset of 12,845 Melbourne massings, incorporating parcel contours, 3D geometry, neighboring buildings, and multi‑view images, and proposes a learned relevance metric to assess morphological compatibility. Experiments with Qwen3‑VL models show that larger model size improves generation quality, multimodal training enhances the use of individual modalities, and multimodal inference yields a stronger contextual signal than isolated inputs.

The paper investigates how the choice of the π parameter in λπ norm-constrained adversarial attacks influences the sparsity and smoothness of the perturbations. By applying two established sparsity metrics and introducing three new smoothness measures—including one based on first-order Taylor approximations—the authors perform extensive experiments on real-world image datasets and various neural network architectures. Their results indicate that λρ norms with π values between 1.3 and 1.5 consistently provide the best balance between sparsity and smoothness, challenging the common use of λ1 or λ2 norms.

The paper introduces Block Parallelism (BP) and Context‑Sharded Block Parallelism (CSBP) to improve training efficiency for Block Diffusion Language Models (BDLMs) with long contexts. By assigning each corrupted‑block computation to a separate rank and sharding the shared clean sequence, CSBP reduces communication overhead and memory usage while preserving training semantics. Experiments on 16 H200 GPUs and 8 H100 GPUs show throughput gains of up to 1.61× and 7.59×, respectively, and higher benchmark pass rates in practical fine‑tuning scenarios.

The paper evaluates twelve financial sentiment models—including dictionary-based methods, finance-specific transformers, and open-source large language models—using linguistic and economic validity criteria. General-purpose LLMs match finance-specific transformers in classification performance but do not yield stronger economic relationships. While several models correlate with earnings surprises, none shows a significant link to next‑day stock returns, and performance is strongest for large earnings beats or misses.

QEncodeBench evaluates whether large language models can translate classical constraint problems into verified quantum phase oracles. The benchmark measures the correctness of generated circuits using an adversarial self‑validated verifier that checks full solution‑set equivalence while enforcing resource limits. Results show that models lacking a reasoning mode perform poorly, whereas enabling native reasoning improves accuracy tenfold; semantic errors dominate, and neuro‑symbolic pipelines close most gaps by delegating critical composition to deterministic procedures.

VákQA is a new Telugu spoken factoid question answering benchmark comprising 2,001 question‑answer pairs across six domains, 2.53 hours of speech audio, bilingual transcriptions, and human‑verified reference answers. The study validates automatic evaluation methods against human judgments, finding that Gemini-as-a-judge best approximates human ratings but is unevenly strict, while open‑weight judges tend to penalize correct Telugu answers that differ in surface form. Using this validated setup, the authors benchmark proprietary and open‑weight models, highlighting challenges such as cultural specificity lost in translation, phonetic confusions from speech input, and cascading ASR‑MT errors.

The paper proposes a hierarchical architecture for long-horizon language‑model agents that must operate over days or weeks without forgetting. It introduces three key components: time‑scale levels that store bounded summaries, a clocked tick as the basic action unit, and cascaded intelligence that escalates tasks to more capable models only after review failures. A ten‑day experiment demonstrated that the agent maintained continuity across context resets, adapted its behavior based on early knowledge, and identified where learned components could be integrated.

The paper introduces a unified evaluation framework for assessing the trustworthiness of large language models, agentic AI, and multimodal systems. It connects output-level, trajectory-level, and cross-modal assessments across eight dimensions—capability, robustness, safety, fairness, transparency, governance, oversight, and efficiency—while preserving system-specific metrics and providing uncertainty estimates. A meta-evaluation layer checks the validity, reliability, and reproducibility of the evaluation itself, and the framework aligns with governance standards and regulatory requirements.

The paper examines when multi‑agent collaboration is beneficial versus single‑agent approaches. It finds that collaboration yields systematic advantages mainly in long‑horizon tasks with sparse dependencies, while single agents perform better in tightly coupled, sequential workflows. The authors introduce SAIGE, a lightweight multi‑agent mechanism that models collaboration as a dynamically evolving graph, and show that it balances context efficiency and task performance without always improving outcomes as more agents are added.

The study shows that while large language model (LLM) annotations of stakeholder consultation submissions are highly reproducible (intraclass correlations > 0.99), they do not reliably capture the intended construct measured by structured survey responses. Divergence between LLM-inferred and survey measures varies by stakeholder group, with business associations expressing more AI risk concern in text than in surveys, and spatial autocorrelation indicates neighboring European countries share similar text-based stances. Despite these divergences, survey-reported concerns remain strongly linked to support for explainability across all levels of divergence.

SkillAA (Skill Abductive Attribution) is a structured skill‑optimization framework designed for frozen language models. It represents skill applicability, execution, and composition in a unified graph, enabling skill selection, attribution‑guided repair, and update validation within the same structure. By contrasting successful and failed executions, SkillAA routes candidate repairs to specific graph objects, updates only the selected local structure, and uses Local and Big Gates to screen candidate changes before commitment, achieving high performance on SearchQA, LiveMath, and DocVQA.

The paper addresses the lack of statistical validity in language‑model‑based network intrusion detection. It introduces traffic‑aware conformal prediction, which calibrates on attacker‑expected traffic to restore coverage guarantees, and further mitigates adaptive attacks by removing attacker‑controllable features, achieving exact pathwise coverage. Experiments on three benchmarks show that this approach maintains coverage while incurring a modest accuracy cost.

The paper introduces Riemannian–Lorentz Parameter Fusion (RLPF), a method for merging a Vision Transformer and a state‑space model without gradient descent. RLPF aligns parameter groups by semantic role, projects them onto a common coordinate system, lifts selected coordinates to the Lorentz hyperboloid, computes a regularized geodesic barycenter, and decodes the result back into the two branches, with a learned gate combining their logits. The resulting fine‑tuned system achieves 82.37 % on CIFAR‑10, 75.04 % on Oxford‑IIIT Pet, and 78.58 % top‑1 accuracy on ImageNet‑1K, surpassing the best‑parent accuracies of 76.54 %, 71.42 %, and 76.42 % respectively.
