Token Sparse Attention: Efficient Long-Context Inference with Interleaved Token Selection

Dongwon Jo, Beomseok Kang, Jiwon Song +1

The quadratic complexity of attention remains the central bottleneck in long-context inference for large language models. Prior acceleration methods either sparsify the attention m…

Rotation-Aligned Key Channel Pruning for Efficient Vision-Language Model Inference

Beomseok Kang, Dongwon Jo, Jiwon Song +2

Vision-Language Models suffer severe KV cache pressure at inference, as a single image often encodes into thousands of tokens. Most existing methods exploit token sparsity through…

CompactAttention: Accelerating Chunked Prefill with Block-Union KV Selection

Jiwon Song, Dongwon Jo, Beomseok Kang +1

Chunked prefill has become a widely adopted serving strategy for long-context large language models, but efficient attention computation in this regime remains challenging. Existin…

FastKV: Decoupling of Context Reduction and KV Cache Compression for Prefill-Decoding Acceleration

Dongwon Jo, Jiwon Song, Yulhwa Kim +1

While large language models (LLMs) excel at handling long-context sequences, they require substantial prefill computation and key-value (KV) cache, which can heavily burden computa…

RelayGen: Intra-Generation Model Switching for Efficient Reasoning

Jiwon Song, Yoongon Kim, Jae-Joon Kim

Large reasoning models (LRMs) achieve strong performance on complex reasoning tasks by generating long, multi-step reasoning trajectories, but inference-time scaling incurs substan…

LiteStage: Latency-aware Layer Skipping for Multi-stage Reasoning

Beomseok Kang, Jiwon Song, Jae-Joon Kim

Multi-stage reasoning has emerged as an effective strategy for enhancing the reasoning capability of small language models by decomposing complex problems into sequential sub-stage…
