Neurons start to glow and fire across the surface.
The evolution log
Watch it grow
Every time Big AI Brain gets an upgrade, we add a snapshot here: what it looks like, what's inside, what it can do. The stage names come from the brain itself; it has to earn each one with a better report card and enough approved meals.
Live right now: the neuron count and connection count on the homepage update as the brain grows. Each new stage adds neurons using function-preserving widening.

Day one: born goofy
What it looks like: A smooth pink brain with googly eyes, buck teeth, blushing cheeks and one sprout on top. Eyes follow your finger. Mouth opens when you tap it.
What's inside: 384 neurons, about 483,000 connections, all random noise at birth. Two hidden layers. Reads 32 characters at a time and guesses the next one.
What it can do:
- 171 clean jokes and 30 knock-knocks, both directions
- Math that shows its work, plus a leveling kids quiz
- 76 facts and 18 mini lessons
- Memory lobe: approved meals answer instantly, credited to the feeder
- Under the hood: explains its own code with pictures
- Five-layer safety lobe and a rewind button
- Grows new neurons when it earns a stage (function-preserving widening)
Coming stages
Teasers only. Each one unlocks when the brain earns it.
🔥Caveman
Visible pathways light up when it answers. Rock knowledge: probable.
🧸Toddler
Little muscles. Don't ask. It's been working out.
🎒Kid
A glasses upgrade and the first bigger brain.
The full path
