Elon Musk is not convinced with China's AI chatbot DeepSeek that rattled the US tech market and wiped out billions from them. The Tesla CEO remains skeptical about DeepSeek, which caused a $500 billion drop in Nvidia’s market cap. Musk doubts DeepSeek’s claims of using only 10,000 GPUs, agreeing with concerns about US export controls, and dismissing the startup’s success as overstated.
