Doubao

Doubao is ByteDance’s flagship family of large models that powers the “豆包” chatbot, voice assistants, and enterprise solutions on the Volcano Engine platform. The models are actively used by hundreds of millions of users: daily token consumption grew from hundreds of billions to tens of trillions in 2025, making Doubao one of the leaders of China’s AI market. The lineup includes Doubao-1.5 Pro and multimodal variants supporting text, images, video, and voice; the models are used in smartphones, cars (“Hey Tesla” in China), and the new Doubao AI phones. From a technical perspective, Doubao is a modern Mixture-of-Experts architecture running on the powerful Volcano Engine cloud platform and optimized for reasoning tasks, code, and multi-step dialogue. Doubao-1.5 Pro delivers outstanding reasoning quality, competing with cutting-edge reasoning models and outperforming the previous generation in math, language understanding, and multitasking. The multimodal stack (the doubao-1-5-thinking-vision-pro model with the Seed1.5-VL VLM) combines an MoE LLM with 20B active parameters and a vision encoder, achieving SOTA-level results on dozens of vision-language benchmarks. With Doubao, you can build chatbots and assistants for the Chinese and international markets, powerful RAG platforms for document work, voice and in-car assistants, AI features in smartphones and super apps, as well as niche solutions for e-commerce, finance, media, and education. The FreeBlock team handles the full development cycle for solutions based on Doubao: selecting the optimal model (reasoning, multimodal, or lightweight), fine-tuning on your data, designing the architecture (RAG, agents, integration with CRM/ERP/telephony/automotive), and reliable deployment in Chinese or hybrid infrastructure. If you want to build Russian-Chinese assistants, voice and multimodal services, or intelligent B2C products based on Doubao, order AI project development with this model from FreeBlock.
