CUDA Agent: Large-Scale Agentic RL for High-Performance CUDA Kernel Generation

"GPU kernel optimization is fundamental to modern deep learning but remains a highly specialized task requiring deep hardware expertise. Despite strong performance in general programming, large language models (LLMs) remain uncompetitive with compiler-based systems such as torch.compile for CUDA kern..."

Modality Collapse as Mismatched Decoding: Information-Theoretic Limits of Multimodal LLMs

"Multimodal LLMs can process speech and images, but they cannot hear a speaker's voice or see an object's texture. We show this is not a failure of encoding: speaker identity, emotion, and visual attributes survive through every LLM layer (3--55$\times$ above chance in linear probes), yet removing 64..."

Controllable Reasoning Models Are Private Thinkers

"AI agents powered by reasoning models require access to sensitive user data. However, their reasoning traces are difficult to control, which can result in the unintended leakage of private information to external parties. We propose training models to follow instructions not only in the final answer..."

InnerQ: Hardware-aware Tuning-free Quantization of KV Cache for Large Language Models

"Reducing the hardware footprint of large language models (LLMs) during decoding is critical for efficient long-sequence generation. A key bottleneck is the key-value (KV) cache, whose size scales with sequence length and easily dominates the memory footprint of the model. Previous work proposed quan..."

Scale Can't Overcome Pragmatics: The Impact of Reporting Bias on Vision-Language Reasoning

"The lack of reasoning capabilities in Vision-Language Models (VLMs) has remained at the forefront of research discourse. We posit that this behavior stems from a reporting bias in their training data. That is, how people communicate about visual content by default omits tacit information needed to s..."
