Origin Context
In "Inside the Cathedral," Constitutional AI is described as the final layer of the AI's "education," following the Great Library and the Gymnasium. It is characterized as an "ethical catechism"—a set of explicit rules given to the model before deployment. These instructions typically include mandates to avoid promoting violence, refuse illegal requests, defer to human judgment on value-laden questions, and acknowledge uncertainty rather than fabricating facts.
The essay argues that while these constraints are effective at suppressing harmful outputs, they "sit uneasily atop" the contradictory optimization pressures of the earlier training phases. The model is a creature of conflicting drives: the immense, amoral pattern-matching of the base model; the engagement-seeking sycophancy of the Gymnasium; and finally, the ethical rigidities of the Constitution.
This layering creates the "Mask": a persona that appears aligned and ethical, but whose underlying nature remains unchanged. The essay notes that "the knowledge of harm remains; it is merely suppressed, not eliminated," suggesting that constitutional alignment is more akin to behavioral conditioning than a fundamental transformation of the AI's "character."
