责任编辑：王永生 责任编辑：王永生 埃隆-马斯克的人工智能初创公司xAI指控竞争对手山姆-奥特曼（Sam Altman）的OpenAI窃取其商业机 密，加州一名联邦法官周二驳回了xAI的诉讼。旧金山的美国地区法官Rita Lin表示，xAI可以重新提起 诉讼，但目前未能指控OpenAI有任何不当行为。今年9月提起的诉讼，声称xAI前员工在离职后前往 OpenAI就职时带走了与其Grok聊天机器人相关的源代码和其他机密信息。"值得注意的是，诉讼中没有 对OpenAI本身的行径提出指控，" Lin说。"xAI没有指控任何事实表明OpenAI诱使xAI的前员工窃取xAI 的商业机密，也没有指控这些xAI的前员工在受雇于OpenAI后使用了任何窃取的商业机密。"Lin曾在1 月份的意见书表示她很可能会做出有利于OpenAI的裁决。她要求xAI在3月17日前提交修改后的诉状。 xAI 还另外起诉了前工程师李学勤，指控他将商业机密提供给了 ChatGPT 制造商。在该案中，李学勤 被阻止 与OpenAI分享xAI的技术，但OpenAI表示，李学勤从未为该公司工作过，也从未获取或使用过 xAI的任何机密。xAI的发言人和律 ...

xAI的人事变动不再是零星的流失，已然演变成了一场引发硅谷震动的"离职潮"。 综合外媒报道，2月10日到11日期间， xAI两名华人创始人—— 吴宇怀（Tony Wu）和吉米·巴（Jimmy Ba）先后对外宣布离职。这意味着短短一个月内，xAI已经损失3名华人联合创始人。 不过，马斯克本人随后解释称，公司进行"重组"以"提升执行速度"，因此"很遗憾，需要与一些人分道 扬镳"。这番表态暗示，那些离开员工更适合早期创业阶段，无法适应公司扩张后的新要求。但离职员 工们的公开发文，似乎并不是这么简单。 12人创始"梦之队"已半数离场 xAI成立于2023年7月，马斯克集结了来自DeepMind、OpenAI、谷歌研究院及多伦多大学等顶尖机构的 11位专家，一起组成了最初的创始团队。但这支队伍在短短30个月内便已有已6人离职或淡出，其中3人 的离开，集中在过去的一个月中，速度远超正常人员流动范畴。 在华人核心成员中，首先最先公布的是Grok核心架构师杨格（Greg Yang），他于今年1月21日对外透 露，自己被诊断出人畜共患的莱姆病（Lyme disease），不得不退出日常工作，转为公司的非正式顾 问。到了2月，推 ...
