ByteDance, DeepSeek race to match US AI leaders

ByteDance, DeepSeek race to match US AI leaders

Key takeaway

  • China's major AI companies ByteDance and DeepSeek are building models designed to compete with Anthropic's Mythos and Claude Code respectively, as Beijing tightens control over the sector.

  • Chinese regulators forced Meta to sell back the startup Manus AI to its original investors, underscoring the government's determination to keep advanced AI development domestic.

  • However, intense price competition among Chinese AI firms and volatile tech stocks are creating headwinds for the ecosystem's profitability and market stability.

3 Key Points

  1. What happened

    ByteDance is developing an AI model to rival Anthropic's Mythos system, while DeepSeek is building a competitor to Claude Code. Separately, Manus AI's former investors repurchased the Chinese startup from Meta this week after Chinese regulators ordered the deal to be unwound.

  2. Why it matters

    China's AI ecosystem is attempting to close the gap with leading US models as Beijing seeks to establish technological self-sufficiency. The regulatory reversal of the Meta acquisition signals Beijing's priority on keeping advanced AI capabilities under domestic control rather than foreign ownership.

  3. What to watch

    A price war among domestic Chinese AI firms threatens to erode corporate profits, while Beijing also grapples with stock market volatility in high-value tech stocks that complicates efforts to maintain steady market growth.

China's artificial-intelligence ecosystem is making a concerted push to develop models capable of matching or surpassing the most advanced systems from the United States. ByteDance, the Chinese tech giant behind TikTok, is reportedly developing an AI model designed to rival Anthropic's Mythos system, one of Anthropic's most advanced offerings. Simultaneously, DeepSeek, another major Chinese AI firm, is touting its efforts to build a model that would compete with Claude Code, the coding-focused variant of Anthropic's Claude suite.

Beijing's approach extends beyond commercial competition. This week, Manus AI's former investors repurchased the Chinese startup from Meta following an order from Chinese regulators to unwind the acquisition. The move underscores Beijing's determination to keep advanced AI capabilities and the companies that develop them under domestic ownership. As Beijing attempts to erect a firewall around its homegrown technology sector, regulatory intervention of this kind has become a key tool to prevent foreign control of sensitive AI assets.

However, China's AI ecosystem faces significant internal pressures that complicate its path forward. A price war among domestic AI firms threatens to erode corporate profits across the sector, and persistent volatility in high-value tech stocks has made it harder for Beijing to maintain the steady upward trend in markets that would support long-term investment and confidence in the sector.

Context & Analysis

China's AI push reflects Beijing's broader strategy to establish technological independence from the United States in a sector the government views as strategically critical. ByteDance and DeepSeek's efforts to build direct competitors to Anthropic's and Stripe's flagship models signal that Chinese firms now see matching US capabilities as achievable. The forced reversal of Meta's acquisition of Manus AI reveals the regulatory framework Beijing has put in place: foreign ownership of advanced AI startups is not permitted, and the government will intervene to restore domestic control even after a deal has closed. This tightening comes as China's policymakers face a dual challenge—maintaining market confidence while supporting domestic innovation—complicated by volatility in tech stocks and a destructive price war among competing local AI firms.
