On June 23, Superhuman, the parent company of Grammarly, announced the acquisition of the AI detection tool GPTZero. Grammarly helps 40 million people write more smoothly every day, while GPTZero, with 19 million users, determines whether an article is written by AI. Both AI generation and detection are trained on vast amounts of human text using the same technical approach, creating a paradox. AI detection may never catch up with AI generation because detection tools require obtaining samples, labeling data, and training a classifier, a process taking as short as two or three months or longer, while model iteration is faster. For example, GPT-4 was released in March 2023, and GPT-4 Turbo debuted in November of the same year, an eight-month interval during which Anthropic released Claude 2 and Meta launched Llama 2. By the time a detection tool completes training, a new model has already been released, reducing accuracy. Additionally, AI hallucination causes misjudgments, marking human-written text as AI-generated or vice versa.
