Chinese AI firm DeepSeek released a preview of its new flagship model, V4. The model can process much longer prompts than its last generation and matches leading closed-source rivals from Anthropic, OpenAI, and Google. V4 is DeepSeek's first release optimized for Huawei's Ascend chips, a key test of China's dependence on Nvidia. China blocked Meta's $2 billion acquisition of AI startup Manus, citing national security grounds. The decision escalates China's AI rivalry with the US.
