Learning Ordinal Probabilistic Reward from Preferences

ICLR 2026poster

Reward models are crucial for aligning large language models (LLMs) with human values and intentions. Existing approaches follow either Generative (GRMs) or Discriminative (DRMs) paradigms, yet both suffer from limitations: GRMs typically demand costly point-wise supervision, while DRMs produce unca…

NExT-OMNI: Towards Any-to-Any Omnimodal Foundation Models with Discrete Flow Matching

ICLR 2026poster

Next-generation multimodal foundation models capable of any-to-any cross-modal generation and multi-turn interaction will serve as core components of artificial general intelligence systems, playing a pivotal role in human-machine interaction. However, most existing multimodal models remain constrai…

CLaSp: In-Context Layer Skip for Self-Speculative Decoding

ACL 2025long

Speculative decoding (SD) is a promising method for accelerating the decoding process of Large Language Models (LLMs). The efficiency of SD primarily hinges on the consistency between the draft model and the verify model. However, existing drafting approaches typically require additional modules to…

Re3Syn: A Dependency-Based Data Synthesis Framework for Long-Context Post-training

ACL 2025long

An important trend in the realm of large language models (LLMs) is the development of longer context windows. However, training LLMs with long context windows to acquire the capability of effectively modeling lengthy inputs is often hindered by the scarcity of naturally long-context data. Existing m…

VCM: Vision Concept Modeling with Adaptive Vision Token Compression via Instruction Fine-Tuning

NeurIPS 2025poster

Large vision-language models (LVLMs) have emerged as foundational tools for real-world AI applications. Despite their remarkable capabilities, current LVLMs process entire images at the token level, leading to significant inefficiencies compared to human cognition, which selectively focuses on high-…
