This feature is based on local regeneration technology, applying the concept of image inpainting to the audio temporal domain, allowing for precise control over structural modifications of songs. It is one of the most finely-grained editing implementations currently available in AI music tools.

• Multimodal Reference Generation: The model supports using text, images, or even videos as reference materials for creating new songs. It encodes heterogeneous inputs into conditional signals that guide the audio generation process. Generating a song from a single image is no longer just a concept—it is a practical feature available in v6, offering short video creators a new pathway to match visual mood with music.

• Sampling Extraction: The model includes built-in source separation capabilities, allowing it to decompose a mix into independent tracks such as vocals, drums, and bass. It supports the precise extraction of individual instrument samples from these tracks for further creative use. The separation quality is cleaner and free of artifacts compared to previous generations, providing music producers with a new creative pathway to extract materials from existing works and rebuild rhythms.

• Authorized Remix (Planned): An upcoming remix plan where artists can voluntarily join a library of tracks. Fans will be able to remix authorized works, and original artists will receive revenue sharing. This feature deeply integrates AI music creation with fan economy, establishing a win-win ecosystem among the platform, creators, and users, and introducing a new interactive model for the music industry.

• Model Tiering Strategy: v6 (flagship) and v6-wild (experimental) are available to Pro/Premier paying users, while v6-mini is freely accessible to everyone. The three-tier model structure corresponds to professional production, style exploration, and general user experience needs. It maintains product quality stratification while reducing the barrier to entry for AI music creation, broadening the product's reach.
