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.
