A research report from CITIC Construction Investment reveals that the first batch of ChatGPT advertisements is set to officially launch in early February 2026. At the outset, these ads will be exclusively displayed to free - tier users and those subscribed to the Go plan, which costs US$8 per month. The billing will follow a CPM (Cost Per Mille, meaning the cost per thousand impressions) model. In the realm of advertising monetization, OpenAI adopts a measured approach. It takes great care to ensure that advertisements do not disrupt the AI - generated responses. Moreover, the responses generated by the AI do not give undue preference to ads. This strategy helps maintain an optimal balance in the user experience. As the user base and conversation volume expand, the marginal cost of large models escalates. In this context, unlocking the commercial potential of free users becomes pivotal for large - model companies to establish a self - sustaining commercial cycle. Given this situation, for large - model companies with a strong focus on the consumer - facing (To C) market, diversifying monetization methods, such as advertising, has emerged as an inevitable path forward.
