Open AI Detector →How GPT-4 Detection Works
GPT-4 from OpenAI produces text with specific patterns that our detector can identify. AI-generated text typically shows uniform sentence lengths, predictable vocabulary choices, formulaic transitions, and a consistent formal tone without contractions or personal voice.
Our detector uses enhanced heuristic analysis including sentence structure uniformity, transition word frequency, vocabulary diversity, contraction usage, punctuation variety, and perspective indicators to score text on a 0-100% scale.
What Makes GPT-4 Text Detectable?
- • Uniform sentence lengths (low burstiness)
- • Overuse of transitions: "Furthermore", "Moreover", "Additionally"
- • Absence of contractions ("it is" instead of "it's")
- • No punctuation variety (rarely uses semicolons, dashes, parentheses)
- • Consistent formality without personal voice
