World models in 2026: places you can walk through, lives still to come
World models now generate explorable places that hold together for minutes. The next frontier is behaviour over years, many lives at once, and results checked against a reality the model has never seen.
Emulating the Earth: what AI weather teaches simulation of lives
Learned weather models are now operational, faster and often more skilful than physics on ordinary days, and weaker on record-breaking ones. The habits that made them trustworthy, daily scoring against what happened and honesty about extremes, are what simulation of lives and economies needs next.
Agents that remember, and people around a working machine
An agent that remembers what a person said predicted their answers four years later better than a persona, in every panel and on every question; an agent given only a life record did no better than a persona. And Living Worlds' crowd predicted how close real people came to a real robot in 7 of 8 recordings nobody had opened.
A billion lives on one GPU, and what only shows at scale
Living Worlds runs more than a billion life-months a second on one desktop GPU and on one desktop processor, with every birth, death, partnership and separation identical across engines; a million-life world that anyone can replay; and an effect of who is born that appears only when lives have to find each other.
