As "RAMmageddon" and the "Thermodynamic Wall" push standard Transformer models to their physical limits, a new era of subquadratic architecture promises to shatter the $O(L^2)$ scaling tax. We break down the SubQ 1M-Preview and its staggering 12-million-token context window, weighing massive efficiency gains against the "lost in the middle" risks of sparse routing. It’s a high-stakes look at whether digital craftsmanship can finally outrun brute-force compute.
