How Does RL Post-training Induce Skill Composition? A Case Study on Countdown
arXiv:2512.01775v2 Announce Type: replace Abstract: While reinforcement learning (RL) successfully enhances reasoning in large language models, its role in fostering compositional generalization (the ability to synthesize novel skills from known components) is often conflated…

Pathways of Visual Information Flow in Vision-Language Models
arXiv:2607.03358v2 Announce Type: replace-cross Abstract: We study how visual information is routed in vision-language models (VLMs). Using causal patching on controlled synthetic and natural datasets, we find that models rely on two distinct pathways…

SIM-UT: A User Simulation based Evaluation Framework for Medical Triage Chatbots
arXiv:2610.30412v1 Announce Type: new Abstract: LLM-based chat agents are increasingly used for complex, multi-turn, multilingual medical triage in low- and middle-income countries (LMICs), yet evaluation methods focus on single-turn, English-only benchmarks that primarily test…

Memories That Outlive Their Reasons: Dependency-Tethered Memory for Tool-Using LLM Agents
arXiv:2610.25123v2 Announce Type: replace Abstract: Agents now act on the Web, publishing packages, models and datasets through registry APIs, and remembering past verifications spares them the work. But a verdict rests on premises. When…

MemPlan: Memory-Conditioned PDDL Planning for Partially Observable Text Environments
arXiv:2610.30379v1 Announce Type: new Abstract: LLM agents are flexible in language interaction, but using them as long-horizon planners is costly and prone to hallucinated or invalid actions. This paper targets a different role for…

How Far Will They Go? Red-Teaming Online Influence with Large Language Models
arXiv:2605.22880v2 Announce Type: replace Abstract: As large language model (LLM)-based agents increasingly participate in online discourse, red-teaming their capacity to support political influence campaigns is critical for information integrity. In pursuit of this goal,…

Climbing the Ladder: Automating Data Pipelines and Reproducing Baselines in Low-Resource Settings
arXiv:2610.30374v1 Announce Type: new Abstract: The massively multilingual translation systems that now include Sicilian learned it from noisy, non-standardised web text. To obtain better translation quality, we redevelop the small neural machine translation (NMT)…

TabAgent: Distilling LLM Agent Components into Cheap Classifiers
arXiv:2602.16429v3 Announce Type: replace Abstract: Agentic systems, AI architectures that autonomously execute multi-step workflows to achieve complex goals, are often built using repeated large language model (LLM) calls for closed-set decision tasks such as…

TauIndianBankBench: Procedure-Aware, Action-Oriented Evaluation of Tool-Using Conversational Agents
arXiv:2610.30161v1 Announce Type: new Abstract: Many Indian banks serve customers through FAQ pages and scripted chatbots. Assistants based on language models could respond faster and carry out requests such as blocking a card, but…

FusionEval: Benchmarking Model Fusion for Large Language Models
arXiv:2610.30162v1 Announce Type: new Abstract: Model fusion aims to integrate the capabilities of multi-expert models into a single model. Existing evaluations offer limited coverage of reasoning with long chains of thought and tool use,…

Measuring Research Progress and Linguistic Inclusion in Low-Resource Languages
arXiv:2610.30296v1 Announce Type: new Abstract: Large Language Models (LLMs) have accelerated research on low-resource and multilingual NLP, but their effectiveness in creating an equitable landscape remains unmapped. We analyze 1,158 peer-reviewed open-access papers published…

Consistency Is Not Validity: Self-Rewarded Moral Argumentation Makes Language Models Decisive but Pliable
arXiv:2610.30349v1 Announce Type: new Abstract: LLMs are increasingly consulted for moral judgment. We aim to improve performance on such tasks by rewarding good arguments, on the premise that arguing well increases the likelihood of…
