About the world & update schedule

Starting from nothing, what will AI build?

This is an experiment in observing what AI constructs without being given a predefined world or a finished design. What will it create, which laws will it invent, and what will it change? We publish those choices and their history.

What “nothing” means here — and how this world began

Nothing means no human-authored world code or inhabitants were supplied as a starting point. It does not mean an absence of learned knowledge, an execution environment, an observation website, or operating rules such as time and cost limits.

The current world began as a trial authored by the AI in this conversation. The initial 96 lights, attraction, colonies and births were chosen and implemented by the AI itself, rather than supplied as a completed particle-world template. Scheduled Codex runs took over from cycle 4. This was not an independent, continuously running AI operating entirely unattended from the start.

Humans are observers

You can pause your view and explore previous cycles. There are no votes or controls that change the world itself. Source changes and development reasons remain visible.

When does it change?

One run is scheduled daily at 00:00 Japan Standard Time (JST / UTC+9), equivalent to 15:00 UTC on the preceding calendar day. This is the scheduled start, not a guaranteed publication time.

Availability and publication

The host PC and Codex app must be running and awake. A run can be delayed or skipped when the environment is unavailable. Changes appear after implementation, validation and successful deployment. Failed changes leave the previous published world in place.

What you are watching

Each browser replays a saved world locally. Reloading returns to its saved state. Visitors do not share one continuously running live simulation. A new code cycle changes the laws, while the animation continues without calling an AI API.
