Liputan6.com, Jakarta - xAI, Elon Musk's artificial intelligence company, has made another significant breakthrough with an update to its "Grok Imagine" feature.
In January 28, 2026, Grok Imagine was upgraded to produce 10-second videos.

This upgrade not only doubled the length of previous videos but also drastically improved the quality of the resulting audio and visuals.
This update allows users to create richer, more immersive video content.
Elon Musk personally announced this upgrade, confirming that Grok's audio and visual quality are now significantly improved.
This feature is expected to be widely available to global users soon, promising a more advanced AI video creation experience.
Users can now access this new capability through the Grok chatbot on the X platform or supported xAI platforms.
Grok Video Length and Audio Quality Improvements
Grok Imagine can now create 10-second videos, a significant increase from the previous 5-second limit.
Some users even reported randomly receiving 10-second videos before the official announcement, indicating a successful testing phase.
In addition to the duration, the audio quality has also seen a drastic improvement, resulting in stronger and clearer sound.
Elon Musk personally stated that "Grok videos are now 10 seconds long and the audio is greatly improved."
This improvement includes more natural audio synchronization with the visuals, making each video feel more vibrant and cohesive.
Grok Imagine's AI API technology automatically combines visuals with synchronized sound.
Each generated video includes background audio that matches the tone and rhythm of the movement, eliminating the need for a separate editing step.
This feature is also capable of handling realistic visuals and movement with synchronized audio effects such as dialogue, music, and sound effects.
How to Use Grok Imagine
The Grok Imagine update focuses not only on duration and audio, but also brings significant improvements to visual smoothness and richer detail.
Sources mention improvements in "cinematic realism," more realistic lighting, more convincing textures, and a more immersive atmosphere.
This makes Grok videos look more realistic and immersive, as if they were professionally produced.
To start creating videos with Grok Imagine, users need to open the Grok chatbot on X or a supported xAI platform.
After enabling the "Imagine video generation" feature, users can enter detailed text prompts.
These prompts should describe the desired scene, style, and actions to achieve the most accurate and consistent results.
This update was launched by xAI in January 27, 2026, with plans for a wider rollout across multiple platforms to global users in the coming days.
Grok Imagine supports video generation from text to video and also from image to video, providing more flexibility for content creators.
Grok's Limitations and Controversies
Despite numerous improvements, Grok currently lacks time controls, meaning users cannot yet set specific clip lengths.
However, this timer feature is planned to be rolled out in the future.
Some early adopters have even speculated that the previously longer video lengths may be related to capacity issues.
Furthermore, there has been controversy surrounding Grok's image and video generation capabilities, particularly regarding its potential for creating explicit or harmful content.
The Malaysian Communications and Multimedia Commission (MCMC) even temporarily restricted access to Grok for Malaysian users following the misuse of AI to generate pornographic content.
Research by AI Forensics also found approximately 800 images and videos generated by the Grok Imagine app containing pornographic content.
