SpaceX 裁撤 Grok Imagine 团队，xAI 视频生成收缩
SpaceX 把 Grok Imagine 的团队裁掉了，马斯克之前还说要加码这个视频生成产品。对比一下，字节跳动还在往视频方向猛投，OpenAI 之前也收缩过 Sora。做视频应用的开发者要留意 Grok Imagine 后续还能不能跟上。
马斯克曾承诺加码 Grok Imagine 视频生成项目，但据 The Information 报道，SpaceX 已大幅裁撤其背后的团队。这次收缩与 OpenAI 此前从高成本 AI 视频生成领域退让的做法相似，Sora 的商业化压力同样来自算力与运营开销。
报道将这一动向放到行业背景下对比：字节跳动等中国公司正在视频生成领域持续加大投入，即梦、Seedance 等产品在成本控制上更具竞争力，抢占市场份额。xAI 一边推进 Grok 模型和 Colossus 训练集群，一边在视频方向削减人力，显示出资源正集中到更核心的模型训练业务。
对开发者而言，这意味着 Grok Imagine 的迭代节奏可能放缓，短期内依赖其 API 构建视频工作流的团队需要评估替代方案。
Elon Musk once promised to double down on Grok Imagine. Now SpaceX has gutted the group behind it, echoing OpenAI’s retreat from costly AI video generation as ByteDance and other Chinese companies gain ground.
