All AI Models Compared
Full accuracy rankings and pairwise agreement matrix for ChatGPT, Claude, Gemini, and Grok — based on 12,673 facts checked.
Every Model, One Dashboard
NoParrot sends the same question to all four major AI models — ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), and Grok (xAI) — and compares their responses at the claim level. This page aggregates that data into a comprehensive view of how every model stacks up.
The accuracy rankings below reflect how often each model's claims are verified by consensus with other models. The agreement matrix shows how closely any two models align. Together, these metrics give you a data-driven picture of AI accuracy that goes beyond marketing claims and synthetic benchmarks.

Methodology
NoParrot sends the same question to all four AI models simultaneously, then uses algorithmic semantic matching to compare their answers at the claim level. Accuracy percentages reflect how often a model's claims are verified by consensus with other models. Agreement percentages are calculated from verified claim clusters where models independently reach the same conclusions.
