Ma Kai, a recent secondary school graduate, took the national university entrance exam, known as the gaokao, in June.
His story came to light when he was interviewed by the Shanghai Morning Post as an ordinary young visitor at the World Artificial Intelligence Conference (WAIC) held in mid-July in Shanghai.
During the interview, he showcased his self-developed app, which is designed to remind his grandfather to take his medication punctually.
He explained that his app was built using a large language model (LLM) called MiniCPM, developed by the Beijing-based AI company ModelBest.
