arXiv:2604.24432v2 Announce Type: replace-cross Abstract: Long-context ability, has become one of the most important iteration direction of next-generation Large Language Models, particularly in semantic understanding/reasoning, code agentic intelligence and recommendation system. However, the standard softmax attention exhibits quadratic time complexity with respect to sequence length. As the sequence length increases, this incurs substantial overhead in long-context settings, leading the training and inference costs of extremely long sequences deteriorate rapidly. Existing solutions mitigate
The paper addresses a critical scalability bottleneck in large language models (LLMs) that has become increasingly pressing as practitioners push for longer context windows.
Overcoming the quadratic time complexity of standard softmax attention is crucial for advancing AI capabilities, particularly in areas requiring extensive contextual understanding like advanced reasoning and agentic systems.
This technical solution promises to significantly reduce computational costs and enable more powerful long-context LLMs, impacting future AI development and application.
