Quant VideoGen: Auto-Regressive Long Video Generation via 2-Bit KV-Cache Quantization

ICML 2026poster

Despite rapid progress in auto-regressive video diffusion, we identify an emerging system–algorithm bottleneck that limits both deployability and generation quality: KV-cache memory. In auto-regressive video generation models, the KV-cache grows with generation history and quickly dominates GPU memo…

Sparse Video-Gen: Accelerating Video Diffusion Transformers with Spatial-Temporal Sparsity

ICML 2025poster

Diffusion Transformers (DiTs) dominate video generation but their high computational cost severely limits real-world applicability, usually requiring tens of minutes to generate a few seconds of video even on high-performance GPUs. This inefficiency primarily arises from the quadratic computational…

Sparse VideoGen2: Accelerate Video Generation with Sparse Attention via Semantic-Aware Permutation

NeurIPS 2025spotlight

Diffusion Transformers (DiTs) are essential for video generation but suffer from significant latency due to the quadratic complexity of attention. By computing only critical tokens, sparse attention reduces computational costs and offers a promising acceleration approach. However, we identify that…

QUEST: Query-Aware Sparsity for Efficient Long-Context LLM Inference

ICML 2024poster

As the demand for long-context large language models (LLMs) increases, models with context windows of up to 128K or 1M tokens are becoming increasingly prevalent. However, long-context LLM inference is challenging since the inference speed decreases significantly as the sequence length grows. This s…
