Introducing brAIAIn.
A parody AI lab. The language model is real.
A language model trained on exactly what it was given: twelve lines of scripture, and one sentence from each customer.
$5 buys one sentence in the next model. It ships as a numbered release with its own notes, paper and status incident, credited to you or to Anonymous.
Talk to brAIAIn.
Ask it anything. It will answer using its commandments and what customers have taught it, which is not much, and it will be confident about it.
Press Peel a layer to hear the same question answered by the version underneath, and the one under that, down to brAIAIn-0. Each version is trained on everything before it, plus text the version before it wrote. Peel it until nothing is left but the first twelve lines.
This runs entirely in your browser. Nothing you type is sent anywhere or saved.

How it works, refunds and gifts · FAQ. Prices in US dollars. One-time payment. No subscription, because nothing recurs except the model.

Trained on you.
Every paid version adds one sentence that a customer paid $5 to include. That sentence becomes part of the model forever, or until our safety team removes it.
Trained on itself.
Each version also reads a few passages written by the version before it. Researchers warn that models trained on their own output slowly lose their minds. We wanted to see it happen.
Fully disclosed.
Other labs will not say what their models were trained on. We will. Here is all of it. It fits on one page.
