arXiv:2602.05305v3 Announce Type: replace-cross Abstract: Generating long-form content, such as minute-long videos and extended texts, is increasingly important for modern generative models. Block diffusion improves inference efficiency via KV caching and block-wise causal inference and has been widely adopted in diffusion language models and video generation. However, in long-context settings, block diffusion still incurs substantial overhead from repeatedly computing attention over a growing KV cache. We identify an underexplored property of block diffusion: cross-step redundancy of attentio
The increasing demand for long-form generative AI content, coupled with the computational overhead of existing methods, necessitates more efficient architectural solutions like FlashBlock.
Improving the efficiency of long-context generation is crucial for scaling generative AI applications across various modalities, making them more accessible and powerful.
This advancement enables more practical and efficient generation of extended outputs in areas like video, text, and other generative models by significantly reducing computational bottlenecks.

FlashBlock directly reduces the computational cost and time associated with generating long-form content using block diffusion models.
This efficiency gain could accelerate the development and deployment of more sophisticated and longer generative AI outputs across industries.
The reduced computational burden may democratize access to advanced generative AI, potentially leading to a wider array of applications and unforeseen creative possibilities.
