Anthropic's method for aligning a model using a written set of principles (a 'constitution') instead of relying mostly on human labels.
Instead of paying humans to rank every harmful output, the model critiques and revises its own answers against an explicit list of principles, then trains on those self-improvements — a step called RLAIF (RL from AI Feedback). This scales alignment cheaply and makes the values auditable: you can read the constitution rather than guess what the labelers preferred. It's a big part of why Claude refuses and reasons about safety the way it does, and it reduces reliance on humans reviewing toxic content.
Plainly
Think of Constitutional AI as a simple recipe for doing the work better. Anthropic's method for aligning a model using a written set of principles (a 'constitution') instead of relying mostly on human labels.
In practice
Use it when you need a repeatable method instead of guessing from vibes. In practice, define the owner, input, output, and failure mode before you rely on it.
