GrowMTP: Can RL Grow Its Own Draft Head?

Minghua He, Lingzhe Zhang, Yuan Liu +2

Reinforcement learning (RL) post-training drives the frontier capabilities of large language models, with its wall-clock dominated by autoregressive rollout generation. Speculative…

Hidden Decoding at Scale: Latent Computation Scaling for Large Language Models

Aiwei Liu, Cheng Shi, Chuhan Wu +44

Scaling Large Language Models (LLMs) has been driven mainly by enlarging the Transformer backbone, but for an already-strong model this requires another round of costly pretraining…

RLCSD: Reinforcement Learning with Contrastive On-Policy Self-Distillation

Leyi Pan, Shuchang Tao, Yunpeng Zhai +5

On-policy self-distillation (OPSD) provides dense, token-level supervision for reasoning models by aligning a model's own distribution with that under privileged context, typically…

UniAudio-Token: Empowering Semantic Speech Tokenizers with General Audio Perception

Yuhan Song, Linhao Zhang, Aiwei Liu +6

Semantic speech tokenizers have become a widely used interface for Audio-LLMs, owing to their compact single-codebook design and strong linguistic alignment. However, their focus o…

How Much Parallelism Is "Free"? A Principle of Near-Free Parallelism for Parallel Decoding

Minghua He, Lingzhe Zhang, Yuan Liu +2

Parallel decoding improves generation efficiency by processing multiple decode positions within a single decode forward, but reported speedups conflate algorithmic token utilizatio…

DiffSpot: Can VLMs Spot Fine-Grained Visual Differences in Web Interfaces?

Linhao Zhang, Aiwei Liu, Yuan Liu +1

Vision-language models (VLMs) have made strong progress on high-level image-text alignment, yet their ability to perceive subtle visual differences remains limited. We study this p…

Beyond Transcription: Unified Audio Schema for Perception-Aware AudioLLMs

Linhao Zhang, Yuhan Song, Aiwei Liu +6

Recent Audio Large Language Models (AudioLLMs) exhibit a striking performance inversion: while excelling at complex reasoning tasks, they consistently underperform on fine-grained…

WeDLM: Reconciling Diffusion Language Models with Standard Causal Attention for Fast Inference

Aiwei Liu, Minghua He, Shaoxun Zeng +7

Autoregressive (AR) generation is the standard decoding paradigm for Large Language Models (LLMs), but its token-by-token nature limits parallelism at inference time. Diffusion Lan…

StableToken: A Noise-Robust Semantic Speech Tokenizer for Resilient SpeechLLMs

Yuhan Song, Linhao Zhang, Chuhan Wu +4

Prevalent semantic speech tokenizers, designed to capture linguistic content, are surprisingly fragile. We find they are not robust to meaning-irrelevant acoustic perturbations; ev…

WildSpeech-Bench: Benchmarking End-to-End SpeechLLMs in the Wild

Linhao Zhang, Jian Zhang, Bokai Lei +4

Recent multi-modal Large Language Models (LLMs) such as GPT-4o have demonstrated strong capabilities of direct speech interaction. However, the lack of specialized and comprehensiv…
