AI Hallucination Prevention

Hallucination is not a model bug. It is the natural consequence of how language models work. The job is not to eliminate it. The job is to prevent it from becoming an action.

Every model in use today produces some rate of confident-but-wrong outputs. The rate varies. The variance does not. Treating that as a model-quality problem is a category error. Even the best model on the best benchmark hallucinates often enough that any production deployment without a containment layer will eventually post a wrong number to a real customer. The question is whether you find out from the model logs or from the customer.

The best teams have stopped trying to make their models perfect and started designing systems where hallucination is contained. The model proposes. A separate layer verifies. Anything that cannot be backed by a citation in the trusted source of truth either gets blocked or gets escalated. The model still hallucinates at the same rate it always did. The customer never sees it.

The three containment patterns that work

First, citation-required outputs: if the model claims a fact, it has to point at the document it came from. Outputs without citations are treated as low confidence by default. Second, action gating: the high-stakes decisions (refunds, commitments, policy claims) cannot be executed by the model. They are proposed by the model and approved by a separate policy engine that checks the proposal against the rules. Third, drift monitoring: the system tracks the rate at which the model's outputs match the ground truth, and raises a flag when it changes.

None of these are model improvements. All of them are system design. That is the point.

Where Navedas fits

Our work is the policy layer that sits between the model and the action. Before any consequential output reaches a customer, a system, or a balance sheet, the policy engine verifies the claim against the source of truth and the rules of the business. The model stays fast. The wrong outputs stay contained.
