Suno V4.5 was released on May 1, 2025, and represented a significant quality jump over V4. Its headline feature was extending maximum song length to 8 minutes — double the previous 4-minute limit — opening the door for longer, more developed compositions.
V4.5 delivered more balanced, fuller mixes with reduced audio degradation and shimmer effects. It expanded genre support with better accuracy for niche genres like punk rock, jazz house, and gregorian chant, plus improved genre mashup capabilities for creative combinations like midwest emo + neosoul.
Enhanced voices offer greater range and emotional depth, from intimate whispers to powerful vibrato. A V4.5+ update in July 2025 added professional audio production tools including the ability to add vocals or instrumentals to existing songs.
Suno V4.5 is preserved on this page as a historical model for comparison. It is no longer selectable for new generations in MeloLab; all new Suno generations use Suno V6.
V4.5 delivers noticeably cleaner audio with better frequency response, reduced artifacts, and improved dynamic range. The overall sound is more polished and closer to professional production quality.
Vocal clarity is significantly improved — lyrics are easier to understand, vocal timbre is more natural, and the AI handles complex vocal runs and melodic phrases with greater accuracy.
Song structures are more musically logical with smoother transitions between verse, chorus, and bridge sections. V4.5 generates arrangements that follow conventional songwriting conventions more consistently.
V4.5 generated complete songs in approximately 20 seconds. It retained the fast generation speed of V4, making it useful for rapid creative iteration and brainstorming.
Improved handling of multi-genre prompts and style blending. V4.5 better understands complex instructions that combine multiple genres or unusual musical directions.
