Keywords: AI, mathematics, formal verification, Lean, counterexamples. Chinese models reshape AI economics - A new analysis argues AI is becoming a commodity business, with Chinese open-weight models putting pressure on pricing, inference costs, and U.S. dominance. Keywords: AI economics, Qwen, Kimi, open models, inference costs, cybersecurity. Ternary encoding trims AI costs - A compact trit-packing method is making ternary AI models more practical by reducing memory use while keeping inference fast on AVX2 and ARM NEON hardware. Keywords: ternary models, BitNet, llama.cpp, inference efficiency, SIMD. A better measure of homeownership - The Minneapolis Fed says the usual U.S. homeownership rate overstates how many adults actually own homes, and proposes a person-centered metric called HPOP. Keywords: housing, homeownership, HPOP, affordability, wealth building. Custom CPU runs DOOM - A hobbyist team got DOOM running on a CPU they designed from scratch, showing how much engineering it takes to make real software work on custom hardware. Keywords: DOOM, FPGA, custom CPU, hardware design, systems engineering. - Qwen Unveils Qwen-Image-3.0 for Realistic, High-Detail…
