Doubao

Doubao is ByteDance's family of large language models and AI products, positioned as one of the most widely used foundation models in China. The model family processes 120 billion tokens of text daily and generates 30 million images, with its main model priced 99.3% below industry averages as of mid-2024 . By late 2025, ByteDance had expanded the line into a full ecosystem including the coding assistant MarsCode , the video-generation tool Seedance, and a multimodal agent model released as Doubao 2.0 Pro in early 2026 .

The product's accessibility has made it a platform for individual creators and "super-individual" businesses. One developer built a subscription-based "girlfriend-soothing" agent on Doubao's API that reached $100 ARR without fundraising or marketing ; podcasters have licensed their voices to generate AI-hosted episodes in their own speaking styles . ByteDance distributes Doubao both through direct consumer apps and via API on its Volcano Engine cloud platform, where the 2.0 series is already available .
