# Start Here

**AI Control Architecture** is an open-source, vendor-agnostic model for governing, securing, assuring, and containing enterprise AI. It gives your organisation a shared way to answer one question about any AI you run — *is this under control?* — and to prove it.

## The idea in one minute

The next major AI failure in the enterprise won't come from a model becoming evil. It will come from giving a **probabilistic system deterministic authority** — over data, decisions, or actions — **without a control architecture**.

An AI touches the enterprise in exactly three ways: what it can **See**, what it can **Decide**, and what it can **Do**. AI Control Architecture bounds each of those, grades how strongly every boundary actually holds — *Declared → Evidenced → Verified → Enforced* — and insists that a **named human owns every consequential outcome**. Controls scale with risk across five tiers, so a low-risk copilot and an action-capable agent never carry the same burden.

The result is a claim you can make, and defend, for any AI you operate:

> We know what it can see, decide, and do. We have graded how strongly each boundary holds. A named human owns every outcome. We can observe it, stop it, and recover.

## Everything here is open

The specification is licensed **CC BY 4.0**, the reference tools are open source, and the model is deliberately vendor-agnostic. It is stewarded by [Neo Control](https://neocontrol.ai), which offers the reference implementation — but you never need Neo, or any vendor, to adopt it.
