What Is JEV? — The System 1 AI Model That Breaks LLM Agent Bottlenecks

Why emitting a single boolean via autoregressive LLMs wastes 48 tokens, 1,420ms, and $0.024. Founded by former OpenAI researcher Diogo Almeida alongside Erik Gafni and Sasha Sheng, TypeSafe AI unveiled Jev — the world's first System One AI model. Operating 200x faster and 400x cheaper with zero token chatter, Jev powers a two-tier AI architecture where high-frequency reflex models handle 100,000 decisions/sec while reasoning LLMs orchestrate high-level strategy.

Attention Is All You Need — How Transformers Conquered AI

In 2017, eight researchers at Google published a paper that changed artificial intelligence forever. By discarding recurrence and convolution entirely in favor of scaled dot-product attention, Transformers unlocked O(1) sequential training operations and laid the computational bedrock for GPT-4, Gemini, and modern generative AI.

How "Ghost Plates" Blind Traffic Cameras — The Physics of Optical Stealth

From retroreflective prismatic films tuned to blind near-infrared (850nm/940nm) ALPR sensors to 12V polymer-dispersed liquid crystal (PDLC) shutter plates, how drivers attempt to evade machine vision—and how modern traffic cameras defeat them with sub-millisecond exposure cycling and multi-spectral flash.
