Researchers have identified two distinct failure modes in large language model reasoning: committed failures where models lock onto incorrect paths early, and persistent uncertainty failures where doubt accumulates throughout reasoning. The framework, validated across 23 model-dataset configurations, provides diagnostic signatures for detecting reasoning failures and offers practical implications for improving self-consistency methods.
Researchers present EASE-TTT, a novel framework combining within-context retrieval with test-time adaptation to improve long-context question answering in smaller language models. The method identifies evidence chunks and converts them into soft attention supervision targets, allowing models to focus on relevant information while processing the full context, outperforming existing retrieval-only and generic adaptation baselines.
Researchers characterize the training dynamics of on-policy distillation (OPD), a technique used to improve large language model reasoning, revealing it operates in a distinct geometric regime compared to supervised fine-tuning and reinforcement learning. The study shows OPD exhibits 'subspace locking,' where cumulative updates rapidly converge to a narrow low-dimensional channel that is functionally sufficient for performance, suggesting OPD has unique training dynamics rather than existing as a simple intermediate between other training approaches.
Researchers introduced UrduMMLU, a 26,431-question benchmark for evaluating large language models on Urdu language understanding across 26 subjects. The evaluation of 30 LLMs revealed significant performance gaps, with Gemini-3.5-Flash achieving 90% accuracy while most models struggle with Urdu-specific and humanities content, highlighting persistent multilingual AI capability disparities.
Researchers introduce DEFINED, a computational framework for assessing creativity in debate using a hierarchical eight-dimensional metric system. The approach combines pre-trained language models with human expert annotations to overcome data scarcity challenges, achieving more accurate scoring than standard LLM evaluators.
Researchers have developed SV-Detect, an AI detection system using steering vectors extracted from language model hidden layers to distinguish human-written from machine-generated text. The method demonstrates robust performance across domain shifts, different source models, and edited content, positioning fake-text detection as a representation-space probing problem rather than surface-level analysis.
Researchers developed a framework separating language proficiency from cultural knowledge access in large language models across 13 locales and 80 models. The study reveals that while English outperforms local languages on culture-agnostic questions, local languages consistently show advantages for accessing culture-specific knowledge once proficiency gaps are controlled for. This finding challenges the assumption that weaker local-language LLM performance indicates weaker cultural knowledge.
Researchers compared supervised learning and large language model prompting approaches for detecting Turkish idiomatic light verb constructions, finding that while zero-shot LLMs struggle with recall, few-shot demonstrations significantly improve performance. The study reveals that careful prompt engineering can match or exceed traditional supervised baselines, though results remain highly model-sensitive.
Researchers introduce TSAQA, a comprehensive benchmark for evaluating time series analysis capabilities in large language models across six diverse tasks and 210k samples. Current LLMs struggle significantly with temporal analysis, with even top commercial models achieving only 65% accuracy, revealing substantial gaps in their ability to handle complex time series reasoning.
Researchers present a theoretical and empirical analysis of softmax normalization limitations in attention mechanisms, demonstrating that as token selection increases, models lose their ability to distinguish important tokens and converge toward uniform selection patterns. The findings highlight gradient sensitivity challenges during training and suggest that improved normalization strategies are needed for more effective attention architectures.
Researchers demonstrate that diffusion language models exhibit superior jailbreak robustness compared to autoregressive models due to their sampling mechanisms' ability to recover from harmful intermediate generations. They introduce a Step-Wise Refusal Internal Dynamics (SRI) signal that enables effective jailbreak detection without modifying inference, generalizing to unseen attacks.
Researchers introduce Trilobyte, a byte-level tokenization approach that enables language models to perform lossless audio compression on full-fidelity 16/24-bit audio files. While LMs outperform FLAC at 8 and 16-bit depths, compression gains diminish at higher bit depths, suggesting practical limitations for real-world audio applications.

Researchers introduce SoCRATES, a new benchmark for evaluating how well large language models can mediate conflicts across diverse scenarios and cultural contexts. Testing eight frontier LLMs reveals that even top-performing mediators resolve only about one-third of disagreements, with significant performance variations based on cultural identity, emotional reactivity, and party composition.
Researchers propose 'self-commitment latency,' a method to detect reward hacking in language models without requiring a separate reward signal. By measuring how early a model commits to its final answer during reasoning, they successfully identified when models rely on prompt shortcuts versus genuine problem-solving with 87.8% accuracy.
RedditPersona is a modular open-source framework that standardizes how language models are adapted to specific online communities by collecting Reddit data, profiling users, and applying five different grouping strategies with standardized evaluation metrics. Tested on 112 subreddits with over 301,000 user profiles, the research reveals a consistent trade-off between model identifiability and distributional alignment across all clustering approaches.
Researchers discovered that RoPE-trained transformer models encode absolute position information despite RoPE only encoding relative offsets, with the leakage originating from causal masking and residual stream components. The findings reveal how different architectural variants—NTK scaling, sliding-window attention, and standard RoPE—balance these position-encoding mechanisms differently, with attention sinks serving as token-anchored stabilizers.
Researchers propose a hybrid pre-training approach for language models that combines masked language modeling with a JEPA-style latent-space prediction objective, creating more semantically-aligned embeddings with better geometric properties than traditional MLM-only approaches despite achieving similar downstream accuracy.

Researchers propose a framework combining SHAP explainability with LLM-generated rationales to improve transparency in automated rubric-based scoring systems for educational assessment. Testing on classroom transcripts reveals fine-tuned language models outperform LLMs in accuracy, but SHAP attributions provide more faithful and transferable explanations than LLM rationales across different model architectures.
Researchers propose LoRi, a low-rank distillation framework that improves implicit chain-of-thought reasoning in large language models by aligning teacher-student model trajectories in a shared low-rank tensor subspace. The method addresses the performance gap between implicit and explicit reasoning approaches, showing consistent improvements across LLaMA and Qwen model families on mathematical benchmarks.
