Harvard and MIT create "The Matrix": 8.3 billion agents precisely mirror real humans worldwide

What occupation, income and values would they have—or even a tiny preference for the color of an app button?

In the past, calculating this chain of probabilities spanning sociology, behavioral economics and psychology would have left countless sociologists and statisticians bald from staying up all night.

Led by Harvard and MIT PhDs, with more than 40 participants from OpenAI, Anthropic, Google DeepMind, xAI and elsewhere, and over 200 top scientists in total, MatrAIx was released, building 8.3 billion agents to simulate the real behavior of humans worldwide.

The giants locked in fierce, bayonet-level competition for the throne of large models this time, seemingly by tacit understanding, joined forces to weave a net—a "digital veil" that imprisons the behavior of all humanity.
