中國AI初創DeepSeek推出高效模型，撼動全球科技股市場
中國人工智能初創公司DeepSeek近日推出了一款免費的AI模型，引發了全球科技股市場的震盪。DeepSeek的模型被認為能以更低的成本和數據需求，提供與美國頂尖AI公司如OpenAI和Google相媲美的性能。這一突破性進展引發了投資者對美國科技巨頭（如微軟、Meta和Nvidia）在AI領域主導地位的質疑，導致納斯達克和道瓊斯指數大幅下跌。
DeepSeek的模型DeepSeek-V3在獨立基準測試中表現出色，並以僅600萬美元的低成本開發，遠低於美國公司動輒數億美元的投入。這一高效模型引發了市場對AI硬件需求（如Nvidia的高性能芯片）可能減少的擔憂，導致相關股票大幅下挫。Nvidia股價一度下跌11%，其他科技巨頭如微軟、Meta和Alphabet也錄得顯著跌幅。
市場分析指出，DeepSeek的成功可能標誌著AI技術發展的一個轉折點，即不再需要依賴昂貴的硬件和龐大的計算資源。這對全球AI產業的未來發展和投資方向提出了新的挑戰。與此同時，投資者紛紛轉向避險資產，美國國債收益率下降，日元和瑞士法郎等低風險貨幣走強。
儘管DeepSeek的崛起引發了市場恐慌，但專家認為，這一技術的長期影響仍需觀察。目前尚不清楚其模型的穩定性、安全性以及是否能夠持續創新。然而，DeepSeek的出現無疑加劇了中美在AI領域的競爭，並可能重塑全球科技格局。
