Chinese AI startup DeepSeek released preview versions of its V4-Pro and V4-Flash models featuring 1.6 trillion parameters and one-million-token context windows, claiming to close the gap with frontier models while maintaining significantly lower pricing than US competitors. The V4-Pro model significantly leads other open source models in world knowledge benchmarks and is only slightly outperformed by Google's Gemini-3.1-Pro. The release comes amid escalating tensions, with the White House accusing China of industrial-scale IP theft and OpenAI, Anthropic, and Google warning of model extraction attacks by Chinese firms including DeepSeek. Multiple Western governments including the US, Italy, South Korea, and Germany have banned or restricted DeepSeek citing national security concerns and illegal data transfers to China.
