1. The Lunar New Year AI Supremacy Battle: Overview
The battle for AI dominance in China has entered a decisive new phase. Timed to the 2026 Lunar New Year (Spring Festival) holiday, ByteDance and Alibaba Group have each unveiled their next-generation flagship AI models in a head-on collision. As The Information reported on January 29, both companies had planned to launch new models around the holiday window, in what has been described as the most consequential battle in China’s tech sector.
The backdrop to this competition is DeepSeek’s unexpected breakthrough during the 2025 Lunar New Year. DeepSeek became a global sensation during that holiday period, wiping $593 billion off Nvidia’s market capitalization in a single day (Reuters). This year, both ByteDance and Alibaba are leveraging the same “holiday effect”—when China’s vast population takes a week off with ample screen time—to compete for AI app users. DeepSeek is also preparing its next-generation model V4 after a year-long hiatus, creating a three-way race.
