Grok 4.5 Hands-On Experience Tried out Grok 4.5 High Fast in Cursor Pro. The specific task was to perform a secondary audit on code modified by GPT 5.5, found a few minor issues, and then fixed them. Actual experience: 1. Speaks Chinese better than GPT 5.5—at least it’s not awkward or uncomfortable 2. Fast mode still feels a bit slow 3. Decent level—at least it can catch things GPT 5.5 missed Looks like Cursor is planning to ditch the Composer series and fully embrace Grok in the future. With the model’s capabilities improving, the massive computing power Old Ma has been stockpiling is finally finding its purpose.
