SubQ launches 12M context LLM with subquadratic attention

By PulseAugur Editorial · [1 sources] ·

SubQ has launched a new frontier LLM, SubQ, featuring a 12 million token context window and a novel subquadratic attention mechanism. This approach aims to overcome the computational limitations of traditional quadratic attention, which quadruples compute with doubled context length. SubQ's learned-sparse attention dynamically selects relevant token pairs at inference time, offering a significant cost reduction compared to full attention models. AI

IMPACT Enables processing of much larger contexts like entire codebases and long agent traces, potentially reducing reliance on retrieval augmentation.

    What "Subquadratic Attention" Actually Means

    <p>SubQ launched on May 5, 2026 with a 12 million token context window and a claim worth slowing down on: the first commercial frontier LLM that isn't built on quadratic attention. The phrase has been on every feed since. Most of the posts about it don't define what <em>subquadra…
