WebsiteAbout
The SubQ model family from Subquadratic Inc. features a fully sub-quadratic sparse-attention architecture that scales linearly with context length (O(n) complexity). Designed for long-context reasoning, the family targets 12M-token context windows with significantly reduced compute costs vs. standard transformer-based models.
