Doubao has begun testing a subscription model for its AI services, marking a shift towards commercialization in the domestic AI sector. The app now offers paid subscription options alongside its free version, with plans ranging from 68 yuan to 500 yuan per month. This move aims to transform unpredictable computing costs into a predictable revenue structure, addressing the challenge of high costs associated with heavy users. The subscription model reflects a broader trend in the AI industry, where companies are moving from user acquisition to profitability. Doubao's pricing strategy is designed to manage costs for resource-intensive features, such as data analysis and video generation, which require significant computational power. This approach highlights the industry's shift from free services to tiered pricing models, as AI companies seek sustainable business models amid rising operational costs.
