ByteDance is intensifying its AI strategy with a “full-stack self-research + scenario explosion” approach, becoming one of the most complete technology giants in the global AIGC field.
In 2025, the total capital expenditure in the AI sector is expected to exceed 160 billion yuan, with ByteDance’s Doubao large model already ranking in the top tier. The Seedance video generation model leads the global rankings, driving the large-scale implementation of technology through an extreme cost-performance strategy.
Meanwhile, its consumer products such as AI toys and AI headphones have become the “best testing ground” for the large model implementation. ByteDance’s AI companion doll “Xianyanbao” has seen its resale price soar to hundreds of yuan on second-hand platforms, and the BubblePal pendant has sold over ten thousand units after its launch; AI headphones have achieved an upgrade in smart interaction functions through integration with the Volcano Ark MaaS platform, with related products exceeding one million units shipped in 2025.
The large model continues to lead, with explosive growth in C-end products, while upstream computing power, edge hardware, and software services form a synergy, presenting a good opportunity for the layout of ByteDance’s AI industry chain.
