The attention bottleneck has a challenger

A 13-person Miami startup called Subquadratic claims to have replaced quadratic attention with a linear-scaling architecture called SSA — and an independent Appen benchmark validates a 56.2× wall-clock speedup at 1M tokens. But a 17–20 point quality gap between lab and production, no peer-reviewed paper, and a graveyard of prior sub-quadratic attempts demand PM-grade skepticism. The verdict: the scaling wall is now empirically documented, the race to break it is real — audit your RAG dependencies now, and watch the LayerLens independent eval in early August.

AI video's Figma moment

Google unveiled Gemini Omni at I/O 2026 — a unified model that generates text, images, and video from a single interface with conversational editing. The competitive question in AI video has shifted from "which model makes the best first clip" to "which workflow lets a team iterate fastest." Two videos already consume 86% of the daily AI Pro quota, no API is confirmed yet, and a new Tsinghua benchmark shows logical reasoning remains the hardest unsolved problem for every current video model.

The agents that act before you ask

The proactive AI agent paradigm is replacing the reactive prompt-response model. Google, Anthropic, and Moonshot are racing to own the layer — and the competitive moat won't be the model, it'll be the policy that decides when to act.
