Earlier versions of the platform were limited to shorter clips and lower visual fidelity. According to the company, the upgrade allows for smoother visuals and clearer outputs, making the generated content more practical for narrative, creative and social media use.

One of the notable changes in Grok Imagine 1.0 is the introduction of more advanced audio features. Users can add expressive character voices and background music designed to align with the visuals. xAI said the combination of voice and music contributes to a more immersive viewing experience.

The company also highlighted improvements in how the model interprets prompts. Imagine 1.0 is said to better handle detailed instructions and follow-up inputs, allowing users to refine scenes without restarting the generation process.
