On July 18th, according to the Economic Observation Network, OpenAI's official website said today that with the use of ChatGPT in the fields of finance, law, and marketing, there will be a "black box" situation due to the inability to verify its accuracy. In order to solve this problem, OpenAI has proposed a new training framework, Prover-Verifier Games (referred to as "PVG"). For example, using small models such as GPT-3 to verify and supervise the output of GPT-4 large models, thereby improving output accuracy and controllability. Recent news shows that OpenAI is making the ability of artificial intelligence (AI) large models closer to the level of human-like reasoning.
