Pangram has developed an AI text detector, known as Pangram 4, which is capable of identifying artificial intelligence-generated text with a high degree of accuracy. The model can detect AI-generated text in 99.66% of cases, with a single false positive occurring every 24,000 documents. Additionally, Pangram 4 is resistant to tools designed to disguise AI writing as human. The company has increased its API prices, with a two- to tenfold increase. This development has implications for the detection and prevention of AI-generated misinformation.
