Recently, AI music startup Suno officially launched the fourth version (v4) of its music generation model. The new version features significant enhancements in audio quality, lyrical accuracy, and song structure, aiming to provide users with a superior music creation experience.

According to reports, the v4 version introduces the "Remaster" feature, an innovative tool that allows users to upgrade older Suno tracks to v4-level audio quality, delivering clearer and more realistic sound. Additionally, Suno has unveiled "ReMi," an AI-powered lyrics assistant that leverages advanced AI technology to aid users in lyric creation, significantly boosting both efficiency and quality.

However, it is noteworthy that the v4 version is currently available only to Pro and Premier subscribers. Suno has not yet announced a specific timeline for when free users will gain access to this new version. Nevertheless, the release has garnered widespread attention, with many users expressing optimism about Suno's future developments.

Beyond improvements in audio and lyrics, Suno has comprehensively upgraded its cover art creation system. According to the company, the system can now generate more unique and stylistically appropriate designs that align with specific musical genres, offering users a broader range of personalized options. Additionally, Suno has updated existing features like "Covers," enabling users to more conveniently reinterpret uploaded audio files, and the "Personas" feature, which allows the saving of style settings for future use.

However, coinciding with the release of the Suno v4 version, the company is also facing legal challenges from music firms. Reports indicate that several music companies have accused Suno and its competitor Udio of using copyrighted music to train their AI models without proper licensing. These allegations have sparked extensive attention and debate, introducing a level of uncertainty regarding Suno's future trajectory.

Despite these legal hurdles, Suno has stated its commitment to continuing to provide users with high-quality, personalized music creation experiences.
