中國初創公司DeepSeek推出R1 AI模型,震動全球科技股

中國初創公司DeepSeek最近推出了一款名為R1的人工智能模型,引發了全球科技股的震盪,尤其是對美國科技巨頭的影響尤為顯著。這款模型被認為能夠與OpenAI和Google等公司的頂尖AI模型競爭,但其開發成本僅為560萬美元,遠低於美國同行的投入。這一消息導致投資者對美國科技公司的高額AI投資產生了質疑,並引發了市場的恐慌性拋售。

Nvidia作為AI領域的主要受益者,股價在1月27日暴跌近17%,創下自2020年3月以來的最大單日跌幅,市值蒸發約5890億美元,成為歷史上最大的單日市值損失。其他芯片製造商如Broadcom和台積電也分別下跌了17%和13%。與此同時,美國科技巨頭如微軟和特斯拉的股價也出現了不同程度的下跌。

DeepSeek的R1模型在數學、常識問答等性能測試中表現出色,甚至在某些方面超越了OpenAI的模型。Nvidia發言人表示,DeepSeek的技術展示了如何利用現有資源開發高效AI模型,並強調其仍依賴於Nvidia的GPU和高性能網絡。然而,市場對DeepSeek的低成本成功感到擔憂,認為這可能預示著AI投資週期的過度炒作。

分析師對DeepSeek的影響看法不一。Citi分析師認為,美國AI公司不太可能放棄使用Nvidia的先進GPU,而Jefferies分析師則指出,DeepSeek的成功可能促使矽谷公司重新關注效率和投資回報率,從而減少對計算能力的需求。Bernstein分析師則對DeepSeek的開發成本表示懷疑,認為其可能低估了其他研發成本。

總體而言,DeepSeek的崛起對美國科技巨頭構成了競爭威脅,並引發了市場對AI投資前景的重新評估。儘管部分分析師認為市場反應過度,但這一事件無疑加劇了全球科技股的波動,並可能對未來的AI發展格局產生深遠影響。
