DeepSeek, the Chinese artificial intelligence startup whose low-cost model stunned the world ‌last year, launched a preview of its ‌highly anticipated new model, the V4, on Friday. The pro version of ​V4 outperforms other open-source models in world-knowledge benchmarks, trailing only Google's Gemini-Pro-3.1 which is a closed-source model, DeepSeek said. Owned by China's High-Flyer Capital Management, DeepSeek is aiming to raise funds ​at a ​valuation exceeding $20 billion, according ​to a report by ‌The Information this month, which also said that tech giants Alibaba and Tencent were in discussions to take stakes.
