The Facts

  • Chinese AI startup DeepSeek released preview versions of its V4 model on Friday, more than a year after its R1 model drew global attention for its performance and reportedly low training cost of under $6 million.
  • The V4 lineup includes two open-source models: V4-Pro, with 1.6 trillion parameters and 49 billion active parameters, and V4-Flash, with 284 billion total and 13 billion active parameters. Both feature a 1-million-token context window.
  • DeepSeek stated V4-Pro outperforms "the world's top closed-source models," trailing only Google's closed-source Gemini 3.1-Pro, while its performance falls "marginally short" of OpenAI's GPT-5.4 by an estimated three to six months.

The Spin


Narrative A

DeepSeek V4 is a genuine leap forward — offering a 1M-token context window, rock-bottom pricing and open-source access that puts frontier-level AI within reach of individual developers. The strategic pivot to Huawei and domestic Chinese chips signals that China's AI ecosystem no longer needs Nvidia to scale. Open-source models aren't just catching up; they're becoming the default.

Narrative B

DeepSeek V4 is still a "preview" for a reason — training problems are documented in the technical paper, and early users report nothing particularly stunning beyond a cheap price tag. U.S. export controls keep cutting-edge chips out of Chinese hands, and Silicon Valley continues to outspend Chinese rivals on top talent. Affordable isn't the same as transformative.
