POPI: Personalizing LLMs via Optimized Natural Language Preference Inference

Large language models (LLMs) are typically aligned with population-level preferences, despite substantial variation across individual users. We introduce POPI, a user-level personalization framework that separates the problem into two components connected by a natural-language interface: a shared inference model that d...

BigO(Bench): Can LLMs Generate Code with Controlled Time and Space Complexity?

BigO(Bench) is introduced, a novel coding benchmark designed to evaluate the capabilities of generative language models in understanding and generating code with specified time and space complexities, and results from evaluating multiple state-of-the-art language models on this benchmark are presented.

DA-Cramming: Enhancing Cost-Effective Language Model Pretraining with Dependency Agreement Integration

This work meticulously design a dual-stage pretraining work flow with four dedicated submodels to capture representative dependency agreements at the chunk level, effectively transforming these agreements into embeddings to benefit the pretraining.

DFAH-Bench: Benchmarking Observable Agent Instability in Financial Decision-Making

DFAH-Bench connects replay observability to evidence, authorization, completion and cost: evidence sufficiency needs direct assessment alongside repeatability, and fixed-state probes reveal higher decision agreement alongside lower agreement with constructed policy labels.

EndoCogniAgent: Closed-Loop Agentic Reasoning with Self-Consistency Validation for Endoscopic Diagnosis

EndoCogniAgent is proposed, a closed-loop agentic framework that formulates endoscopic diagnosis as a controlled state update process for integrating complementary visual and textual evidence and introduces EndoAgentBench, a workflow-oriented benchmark to evaluate diagnostic agents across a comprehensive diagnostic cha...

SpeakerMem-R1: Speaker-Centered Dual-Track Memory for Multi-Party Dialogue

SpeakerMem-R1 is proposed: its dual-track memory stores speaker-labeled verbatim messages and derived states organized into person-level and group-level views, then combines evidence from both tracks by entity, event, and time at query time, and ablations show that the verbatim and structured tracks, as well as person-...

Beyond Repeated Sampling: Learning Search Policies for LLM Reasoning

A small concept generator is optimized with reinforcement learning so that its concepts maximize the downstream success of a larger, frozen answer generator, and can thus be trained into an effective, reusable search policy for a much larger one.

Measuring the Serving Stack Instead of the Model: Hidden Confounds in Local Tool-Use Evaluation

It is shown that measured outcomes can depend on the serving layer rather than model behavior alone rather than model behavior alone, and a checklist for treating serving behavior as part of the evaluation protocol is concluded.

Capable yet Parsimonious: Extracting and Characterizing Hidden Chain-of-Thought in Frontier Models

It is found that Astra exhibits token-efficient directed reasoning, selecting a correct trajectory earlier, while resolving elementary steps internally and externalizing only crucial reasoning, which provides a behavioral lens on frontier-model reasoning beyond benchmark scores.

Receptiveness, Not Sycophancy: Distinguishing Engagement from Deference in Language Models

A central concern with language models is sycophancy: their tendency to defer to users'views at the expense of independent substantive judgment. In parallel, work on social sycophancy has focused on behaviors such as validation and positivity that may signal inappropriate deference. Yet the markers of social sycophancy...

TransBERT: A Framework for Synthetic Translation in Domain-Specific Language Modeling

TransBERT, a novel framework for pre-training language models using exclusively synthetically translated text, is presented, and TransCorpus, a scalable translation toolkit is introduced, a scalable translation toolkit for building high-quality NLP resources in low-resource language/domain pairs.
