Suno v4.5 at a glance
Suno v4.5 broadened genre coverage and mashups, improved vocals and prompt interpretation, sped up generation and extended songs to 8 minutes.
What changed with Suno v4.5
On May 1, 2025, Suno released v4.5, which it called its most expressive music model so far. It follows requested genres more closely, handles combinations such as EDM with folk more coherently, and gives vocals more range and emotional depth.
Suno said v4.5 interprets descriptive prompts about mood, instruments and texture more accurately, generates faster, and can make songs up to 8 minutes long. It added a prompt enhancement helper and upgraded Covers and Personas, which can now be combined.
Why Suno v4.5 matters for businesses
For businesses, better control over style and length made AI music more practical for background tracks, jingles and social video, but commercial use depends on your Suno plan and terms, and the legal landscape around AI music was still shifting.
