马斯克xAI豪掷120亿扩张算力，Grok能否逆袭AI江湖？

Group 1 - The core focus of the news is that Elon Musk's AI startup xAI is seeking to raise $12 billion in funding to expand its operations, primarily to purchase NVIDIA's latest AI chips and build a large data center for its AI chatbot Grok [1][3] - Over 80% of the funds will be allocated to NVIDIA's H200 series or its successor Blackwell architecture AI chips to meet the explosive demand for computational power required for Grok's model training [1][3] - The remaining funds will be used to construct a super-sized data center that will integrate thousands of NVIDIA GPUs, creating a high-performance computing cluster optimized for Grok [3] Group 2 - xAI plans to adopt an innovative "leasing model" to support its computing needs, aiming to reduce initial investment pressure and lower costs through scaled operations in the long term [3] - Since its launch, Grok has attracted attention for its "real-time access to X platform data" and unique "rebellious conversational style," although it still lags behind OpenAI's GPT-4o and Google's Gemini Ultra in terms of technical strength and performance [3] - This funding round is seen as Musk's strong bet on Grok's future development, indicating that the global AI competition has shifted from mere technological innovation to intense competition in capital and computing power [3]
