AI圈的"大戏"迎来终极反转！ 日前，英伟达与OpenAI的"千亿合作告吹"的传言喧嚣尘上。 据传，OpenAI被曝 "嫌弃" 英伟达AI芯片；英伟达内部则对OpenAI商业模式可持续性、竞争压力存疑。 双重传闻叠加，一度加剧了市场猜测与恐慌。 不过最新消息称，英伟达即将敲定200亿美元投资OpenAI的新协议，这笔投资虽较千亿意向大幅缩水， 却仍是英伟达有史以来最大单笔投资。 此前一天，OpenAI奥特曼已率先在社交平台主动示好，亲手按下风波缓和的按钮。 双方的合作本就是一场双向奔赴的"各取所需"： 随后，黄仁勋在采访中直接"辟谣"，直言千亿美元投资"一切正常、按部就班"，压根没所谓的停滞一 说。 这场双向表态，总算让合作风波按下暂停键。 不过后续走向，依旧牵动着全球AI行业的神经。 狂热过往 这场让全球AI圈沸腾的巨投纠葛，早在去年9月就拉开了序幕。 当时，黄仁勋与OpenAI CEO山姆·奥特曼同台亮相，高调官宣签署非约束性战略合作意向书。 双方计划联手部署至少10吉瓦算力的英伟达系统，投资规模最高冲到1000亿美元，同时由英伟达独家为 OpenAI供应数据中心芯片。 "芯片霸主+AI模型龙头"的强强联 ...
