DeepSeek V4 Signals a New Phase in the U.S.-China AI Rivalry

Chris McGuire

Chinese artificial intelligence (AI) startup DeepSeek released a version of its long-awaited V4 large language model on Friday. It’s the most significant update since the release of the version that rattled global tech markets more than a year ago. Like DeepSeek’s previous models, V4 is open source, meaning it is available for anyone to download, use, and modify. The company claims the new model rivals leading closed-source systems from American firms—like Anthropic’s Claude, OpenAI’s ChatGPT, and Google’s Gemini—on major benchmarks, while outperforming its rival open-source models.

The release has again trained attention on the intensifying U.S.-China AI competition. Adding to the tension, the White House’s science and technology office has accused foreign entities—primarily Chinese ones—of conducting large-scale efforts to extract knowledge from U.S. frontier AI models, a broadside widely seen as directed at DeepSeek.
