Suno released v5.5 on March 26 and called it its "most expressive model yet." The three new features are all about you: it can clone your singing voice, fine-tune on songs you wrote, and learn what styles you like. The weak spots are just as concrete. Jazz and classical still come out uneven, you can't edit fine details, free users don't get the new model, and the copyright lawsuits aren't settled.
What v5.5 adds
Voices is the feature Suno users have asked for most. Record or upload at least 30 seconds of clean vocals, read a random phrase to verify it's your voice, and the resulting voice model stays locked to your account. It's available on Pro and Premier only.
Custom Models lets you upload six or more original tracks you own. v5.5 learns your chord progressions, production habits and vocal style, training takes a few minutes, and you can keep up to three models. The terms say plainly that the uploaded tracks must be yours.
My Taste tracks what you like and nudges new generations in that direction. Add the 12-stem export and the DAW-like Suno Studio from earlier releases, and Suno now works more like a tool for musicians who want a draft they can keep editing. The company reports 2 million paid subscribers and $300 million in annual recurring revenue.
What it still can't do well
Some genres are weak. Pop, electronic and hip-hop sound convincing. Jazz, classical and niche world styles are hit-or-miss, and anything that depends on the feel of real players gives itself away.
You can't fine-tune the details. Suno gives you a complete song with vocals, but if you want bar 32 voiced differently or one track mixed another way, you have to export the stems and do it in a DAW. There's no note-level editing inside Suno.
Free users don't get v5.5. The free tier is stuck on v4.5, with about ten songs a day for personal use only. Voices, Custom Models and Studio all require a paid plan.
There's no official API. Developers depend on unofficial wrappers, so there's no approved way to build Suno into a product.
Commercial use and copyright
The paid plans are clear. Songs you generate while subscribed to Pro (about $10 a month, roughly 500 songs) or Premier (about $30 a month, roughly 2,000 songs plus Studio) come with commercial rights, so you can use them in videos, ads and podcasts.
The law is less settled. Suno reached a settlement with Warner Music and now trains on licensed material, and the pre-settlement v3.5 and v4 models are being retired under that deal. The Sony and UMG suits are still open, and settlement talks reportedly stalled in April. The U.S. Copyright Office also hasn't changed its position: music generated entirely by AI, with no human authorship, can't be registered. You can use the songs commercially under the plan terms, but whether they count as copyrightable works is still an open question. If you need commercial rights, generate on a paid plan and keep records of what you made and when.
