xAI updates Grok Imagine model — now it generates video with character speech and in better quality
The latest version of the AI video generation model is now available for free on the Grok website and its mobile apps for iOS and Android. Following its initial release, this update introduces significant new features and enhancements.
What's New in Grok Imagine v0.9?
- New 'Speech' Mode: Users can now make characters speak by providing text. This joins the existing Custom, Fun, and Spicy modes, the latter of which allows for videos with partial nudity and suggestive movements.
- Longer Videos: The model can now generate videos up to six seconds in length.
- Rapid Quality Improvement: Social media users are highlighting the dramatic improvement in quality since the model's initial release in early August 2025.
A Look Back: The Previous Version
For comparison, the previous version of the model lacked the ability to add speech to characters, which underscores the significant progress made in this latest update.
