Methodology

NoParrot sends each question to multiple AI models simultaneously, then uses algorithmic semantic matching to compare their answers at the claim level. Claude Haiku's accuracy is determined by how often its claims are verified by other models through independent consensus — not by comparing against a static "correct answer" dataset.
