Devlog #2:
our test world is ready to try, first real run tomorrow
Date: 2026-08-11
Hey everyone, here’s a update on what we’ve been building with Planetarium.

What we’re building:
We’re making a benchmark. That’s a pretend little world where we put an AI in charge and see if it can survive and get useful stuff done on its own. No remote control, no holding its hand. Just the AI, the world, and a job to do.

What got done lately:
We locked in the size and shape of the world. It’s now a real, proper size, about a thousand squares by a thousand squares, and we’ve confirmed it’s actually built that way and not just sketched on paper.We finished the safety plumbing too. All the behind the scenes machinery that lets us safely drop an AI into the world and watch what it does is in place now. The AI’s private login details stay out of the saved results, and everything we produce is clearly marked as a practice run rather than an official score.We also cleaned up our own decision notes so the record of what we agreed on is tidy and signed off.On top of that, we ran a quick practice round with a fake stand-in, basically a scripted dummy and not a real AI, just to check the world and the recording system work from start to finish. They did.Where things standThis is still a practice version. No real AI model has been tested in it yet, and nothing we make counts as an official result. We call it “not yet certified” on purpose. We don’t want to claim a score we haven’t actually earned.

What’s next:
The benchmark needs a bit more finishing, but it’s close. Tomorrow we’re running our very first real AI model through it, and we’re paying for it ourselves with our own credits, not a free trial. That’ll be the first time a genuine model tries to survive and make progress in our world.After that there are still a few owner-only steps before any result can be called official. Proper sign-off, locking the setup so results can’t be messed with.
First real run.
