China's DeepSeek releases preview of long-awaited V4 model as AI race intensifies

DeepSeek, a Chinese AI startup, released a preview of its V4 large language model, which is open source (meaning developers can download, run locally, and modify the code) and optimized for agent-based tasks like knowledge processing. The release intensifies competition in the AI sector, particularly between the U.S. and China, though it remains unclear which chips (processors used for training) were primarily used to build V4, given U.S. export restrictions on advanced Nvidia processors to China.
