AI detectors, in general, cannot determine which specific AI model produced a piece of text. The purpose of AI detectors is to identify whether content is AI-generated rather than to pinpoint the tool responsible for creating it. Some advanced tools have been developed for model attribution; however, they have not yet reached a substantive level of reliability and remain in development.
The core challenge is that different AI models share similar training patterns and statistical tendencies, making it difficult to distinguish their outputs from one another. What detectors can tell you reliably is the probability that content is machine-generated. For a full breakdown of how detection works, read our post on How to Tell If Something Was Written by AI. Run any document through Quetext’s AI Detector for a sentence-level assessment.
