Momentum
GPTZero AI Detection Model 3.7b is an AI text detection model released in August 2025 by GPTZero (founded by Edward Tian at Princeton University). It is exclusively a text-based detection system built on an end-to-end deep learning pipeline with seven internal components, including perplexity and burstiness analysis, a sentence-level classifier, and a Paraphraser Shield. The model detects AI-generated text from models such as GPT-4.1, GPT-5 (without explicit training), Claude Sonnet 4, Gemini 2.5, o3, and other LLMs. In June 2026, GPTZero was acquired by Superhuman (Grammarly) for $88 million.
