Suno V4 was released on November 19, 2024, representing a major leap in AI music quality with cleaner audio, sharper lyrics, and more dynamic song structures. While V3.5 first brought mainstream attention, V4 solidified the quality that made Suno the market leader.
V4 introduced several landmark features: Remaster (enhance tracks made with older models to V4 quality), Lyrics by ReMi (an AI lyrics assistant for creative songwriting), Covers (upload audio and reimagine it with a prompt), and Personas (capture vocal style and vibe from a track for reuse).
On MeloLab, Suno V4 remains available as a fast, reliable option with a max duration of 4 minutes per generation, ideal for quick prototyping and creative brainstorming.
Suno V4 V4 should be evaluated by its real output behavior: how it follows structure prompts, handles vocals or instrumental passages, responds to genre tags, and fits into a repeatable creation workflow. On MeloLab, Suno output can be tested beside other models so creators can choose it for songwriting, scoring, and content production when its tone, speed, and control style match the project.
