OpenAI's AI chatbot, ChatGPT, launched just a year ago, has rapidly amassed 170 million users. To stay competitive, OpenAI has been updating its product versions and introducing paid services. Meanwhile, the company has seen frequent changes in its executive team, and investor Microsoft has announced an equity stake. Tech giants like Google and Amazon have also rolled out competing products. The AI chatbot applications represented by ChatGPT are expected to evolve towards more personalized directions, but their generative capabilities face data acquisition bottlenecks, which could slow their growth rate.
