Architecture-Aware Reinforcement Learning Makes Sliding-Window Attention Competitive in Math Reasoning

Kai Liu, Peijie Dong, Xinchen Xie +5

The rapid progress of reasoning and agentic large language models (LLMs) has increased the demand for long-context inference, but self-attention (SA) scales quadratically with cont…

JanusCoder: Towards a Foundational Visual-Programmatic Interface for Code Intelligence

Qiushi Sun, Jingyang Gong, Yang Liu +6

The scope of neural code intelligence is rapidly expanding beyond text-based source code to encompass the rich visual outputs that programs generate. This visual dimension is criti…

Beyond Mode Collapse: Distribution Matching for Diverse Reasoning

Xiaozhe Li, Yang Li, Xinyu Fang +10

On-policy reinforcement learning methods like GRPO suffer from mode collapse: they exhibit reduced solution diversity, concentrating probability mass on a single solution once disc…

What and When to Distill: Selective Hindsight Distillation for Multi-Turn Agents

Xiaozhe Li, Tianyi Lyu, Yang Li +6

Reinforcement learning can train LLM agents from sparse task rewards, but long-horizon credit assignment remains challenging: a single success-or-failure signal must be distributed…

TTE-Flash: Accelerating Reasoning-based Multimodal Representations via Think-Then-Embed Tokens

Jianpeng Cheng, Xian Wu, Jiangfan Zhang +10

Recent research has demonstrated that Universal Multimodal Embedding (UME) benefits significantly from Chain-of-Thought (CoT) reasoning. In this paradigm, a generative model produc…

daVinci-LLM:Towards the Science of Pretraining

Yiwei Qin, Yixiu Liu, Tiantian Mi +12

The foundational pretraining phase determines a model's capability ceiling, as post-training struggles to overcome capability foundations established during pretraining, yet it rem…
