Blurry Window Attention

arXiv:2606.09862v1 Announce Type: new Abstract: The Softmax Attention operation in Transformer language models has a quadratic complexity in the sequence length and a growing state size in the form of KV cache, which becomes a bottleneck in long context scenarios. To overcome this limitation, alternative architectures with linear complexity and finite state size have been introduced, such as State-Space Models (SSMs), Linear Attention (LA), and Attention with Bounded-memory Control (ABC). Though linear models achieve similar language perplexity as Transformers, they are still behind in tasks w

Why this matters
Why now

Ongoing research into Transformer limitations is actively driving the search for more efficient AI architectures, making improvements to attention mechanisms a critical development. This research addresses the immediate need for improved efficiency as AI models grow larger, pushing the boundaries of what is computationally feasible.

Why it’s important
