About Suno V4
Suno V4 is the fourth major music generation model from Suno, the Cambridge, Massachusetts company behind the most widely used text-to-song tool. Announced on November 19, 2024 as a beta for Pro and Premier subscribers, V4 promised cleaner audio, sharper lyrics, and more dynamic song structures than the V3.5 model it succeeded. The release arrived five months after Sony Music, Universal Music Group, and Warner Music Group sued Suno over the training data behind its models, a case Suno has defended on fair use grounds.
V4 shipped alongside a wave of new tooling: Remaster to upgrade older tracks to V4 quality, a lyric-writing assistant called ReMi, improved Cover Art, and V4 editions of the Covers and Personas features. On Artifio it runs in the same workspace as 100+ other models from a single wallet, pay-per-generation.
Features
- Generates complete songs with vocals, instrumentation, and lyrics from a text prompt.
- First generation runs up to 4 minutes; the Extend function continues a track past that cap.
- Covers reimagines uploaded audio, from voice memos to full tracks, in a new style while keeping the original melody.
- Personas captures the vocal character and style of a track so later generations stay consistent with it.
- Remaster upgrades songs made with earlier Suno models to V4 audio quality.
- ReMi, an AI lyrics assistant introduced with V4, drafts and refines lyrics inside the creation flow.
What people use it for
- Full demo songs with sung vocals from a written concept or a finished lyric sheet.
- Restyling a hummed voice memo or rough recording into a produced track via Covers.
- Keeping one consistent vocal identity across an EP or a series of tracks with Personas.
- Background music for videos and podcasts where a 3-4 minute song structure fits.
- Refreshing older V3-era generations to better audio quality with Remaster.
Reported strengths
- Noticeably cleaner audio and sharper lyric pronunciation than V3.5, per Suno's own release notes and press coverage of the launch.
- Music Business Worldwide reported users describing V4 vocals as hard to tell from human singing.
- Dynamic song structures: verses, choruses, and bridges land in sensible places without manual arrangement.
- The surrounding toolset (Covers, Personas, Remaster) makes V4 usable as an iteration engine rather than a one-shot generator.
Reported limitations
- A single generation caps at 4 minutes; longer pieces require chaining Extend steps, which can drift in style.
- V4 launched as a beta restricted to paid Suno tiers, and its outputs on Suno's free tier are non-commercial with ownership retained by Suno.
- The model's training data is the subject of an unresolved copyright lawsuit brought by the three major label groups in June 2024, which may matter for commercial users weighing legal risk.
- Superseded twice within a year: V4.5 (May 2025) doubled the length cap and improved genre accuracy, so V4 is no longer Suno's best-sounding option.
