ByteDance's AI application Doubao has reached over 100 million daily active users, marking it as the company's lowest-cost blockbuster product. This milestone follows Douyin's success, with Doubao achieving significant user growth through organic downloads and content popularity. The application is expanding into AI+hardware and AI+consumer applications, and is set to collaborate with CCTV's Spring Festival Gala in 2026. Despite its unclear monetization strategy, Doubao's large-scale MaaS commercialization has exceeded expectations, delivering high gross margins.
