Cursor Partners with SpaceXAI to Train Grok 4.5 and Integrates It into Editor
 Berryxia.AI@berryxia
Elon把Cursor 终于下狠手了！
Cursor和SpaceXAI合作训练了Grok 4.5，并直接集成到Cursor里。
他们称这是目前最强的模型，而且是Cursor第一次把重点从纯软件工程扩展到更广的场景。
Grok 4.5和他们之前的Composer系列是两个量级的模型，Composer 2.5还会继续存在并迭代新版本。
简单来说，Cursor现在把xAI的顶级模型直接拉进来当主力，首周还给双倍用量。
这其实是Cursor在模型策略上的明显转向：
不再只靠自己训小模型或者接第三方，而是和xAI深度绑定，把Grok作为核心高性能选项推给用户。Show More

We've partnered with SpaceXAI to train Grok 4.5.
It’s our most powerful model yet and the first we've built for more than software engineering.

One Sentence Summary
Cursor announces collaboration with SpaceXAI to train Grok 4.5, directly integrated as the most powerful model yet, with double usage quota in the first week.
Summary
The tweet references cursor_ai's official announcement, explaining that Cursor partnered with SpaceXAI to train the Grok 4.5 model and integrate it directly into the Cursor editor. This model is touted as the most powerful yet and marks Cursor's first expansion beyond pure software engineering to broader scenarios. Grok 4.5 is a different magnitude compared to the previous Composer series (e.g., Composer 2.5), which will continue to exist and receive new versions. The partnership signals a clear shift in Cursor's model strategy: instead of only relying on its own small models or third-party models, it now deeply binds with xAI, pushing Grok as the core high-performance option for users, with double usage in the first week to encourage trial.
