Company
Built to seek the truth.
Based AI™ is a research company building maximally truth-seeking models for anyone who depends on accurate information.

The quality of a model’s answers depends on the quality of what it learns from.
We train on curated corpora written by leading experts in science, engineering, computer science, cryptography, economics and metaphysics. Every source is selected for signal and screened to exclude low-signal web content and institutionally captured material. Each model is evaluated before release, and we publish its architecture, its scale and how its training data was sourced.
Operating principles.
Five principles decide what we release, what we retire and what we decline to build.
Disclose the model
Every model publishes its architecture, parameter scale and intended use. A system has to be described before it can be evaluated.
Curate for signal
Training data comes from expert-authored sources and is screened for low-signal and institutionally captured content.
Show the evidence
Every claim carries a path to its source material. Checking an answer should be easier than accepting it.
Correct errors openly
Our models do not claim certainty. We build systems that surface errors early and record each correction.
The user decides
Models reason, summarize, analyze and critique. Final judgment stays with the person using them.
