The Grok app, an AI-powered video creation tool, has released its latest update (version 1.1.42) on the App Store, enhancing its Imagine feature. The update introduces a display showing the number of videos being generated simultaneously within the app. Additionally, Grok-4, presumably an advanced version of the app, is now available to premium subscribers. The app also auto-generates image prompts when users select "Create your own" under the Imagine video section on the X platform. Users have suggested further improvements, such as enabling video generation through a long tap on images in X posts, which would redirect to Grok's Imagine feature. These developments highlight the app's focus on making AI-driven video production more accessible and creative at lower costs.
