Judging in Latent Space: Efficient Generative Reward Modeling via Semantics-Preserving Compression

Reward modeling often requires jointly representing and reasoning over multiple evaluation criteria, yet verbalizing this process token by token can incur substantial inference cost. Recent work on latent reasoning suggests that continuous states may support this computation more compactly. We introduce LatentGRM, a la...

Flux Attention: Context-Aware Hybrid Attention for Efficient LLMs Inference

Flux Attention is introduced, a context-aware framework that dynamically optimizes attention computation at the layer level by integrating a lightweight Layer Router into frozen pretrained LLMs, which adaptively routes each layer to FA or SA based on the input context.

ProgramTab: Boosting Table Reasoning of LLMs via Programmatic Paradigm

The ProgramTab framework is proposed, which guides LLMs employing in-context learning to perform tabular data preprocessing with Python code, as well as the momentous contents extraction with row and column extraction and SQL generation, demonstrating that the ProgramTab framework effectively deals with table-based rea...

MMLongEmbed: Benchmarking Multimodal Embedding Models in Long-Context Scenarios

This work introduces MMLongEmbed, the first comprehensive benchmark for evaluating MEMs in long-context scenarios, and finds that current architectures rely heavily on superficial feature matching and struggle to capture deep semantic and structural dependencies.

SABER: Stability-Aware Early Exit for LLM Reasoning via Adversarial Branch Probing

This work proposes SABER, a training-free framework for stability-aware early exit via adversarial branch probing, and shows that SABER reduces reasoning token consumption by 30.2% on average while maintaining competitive accuracy with full-length reasoning.

Crossing the Reward Bridge: Expanding Reinforcement Learning with Verifiable Rewards Across Diverse Domains

This work provides a scalable and effective framework for extending RLVR beyond the limitations of pattern-based verification to complex, noisy, real-world domains, and generalizes strongly to seven out-of-distribution benchmarks.

Data Foundations of Long-Context Language Models: A Survey

As the context window of Large Language Models (LLMs) continues to expand, the data required to effectively train and evaluate these capabilities remains underexplored. With existing research primarily focuses on architectural optimization, there is a need for a systematic, data-centric review. This survey bridges th...
