Suno Retired Every Model Before v6: Why It Happened and What It Means for Your Old Songs

On September 9, 2026, I opened Suno to finish a track I had been extending on v5.5 for two weeks, and the model picker had three options I had never seen and none of the ones I had been using. That was the whole announcement for most of us. v4, v4.5, v4.5+, v5 and v5.5 were gone as generation options, replaced by v6, v6-wild and v6-mini, and the only warning most people got was an email a few days earlier with 500 credits attached.

Here is the short version. Suno retired every model before v6 because it agreed to in November 2025, as part of the settlement that ended Warner Music Group’s copyright lawsuit against it. The old models were trained on music the labels said was used without permission. The new ones were built with Warner, BMG and Believe, and the deal required the old ones to go when the licensed ones arrived. Your existing songs are not deleted. They stay in your library, they play, they share, and you can still cover or remaster them. What you cannot do is generate anything new on the old models, and any extension, remix or cover of an old song now runs through v6. The download caps that landed on September 3 are a separate change from the same settlement, and for working musicians they matter at least as much.

The rest of this piece walks through the paper trail, what v6 actually is, what happens to old songs in practice, what the retirement does and does not change about ownership, and what I would do this week with a library of pre v6 material.

The Lawsuit Theory Was Right, and the Paper Trail Is Public

The subreddit has been arguing for months about whether the retirement was a product decision or a legal one. It was a legal one, and Suno never hid it. The commitment was simply buried in a press release most users never read.

Go back to June 2024, when the major labels sued Suno and Udio in the United States, alleging both companies trained on copyrighted recordings without a license. Suno’s position was that the training qualified as fair use under US law. Then on November 25, 2025, Warner settled. Music Business Worldwide’s report on the Warner settlement quoted the joint release directly: in 2026 Suno would launch new, more advanced and licensed models, and when those models launched, the current models would be deprecated. The same release said downloading audio would require a paid account going forward, that free tier songs would become playable and shareable but not downloadable, and that paid users would get monthly download caps with the option to pay for more. All of that was announced nine and a half months before any of it happened, days after Suno closed a 250 million dollar funding round at a 2.45 billion dollar valuation.

On August 10, 2026, Suno published its update on downloads policy and Terms of Service, which put numbers on the caps and repeated the model promise in plainer words: when the new models launch, all prior models will be retired. Two days later it announced a partnership with BMG. On September 8 it announced a deal with Believe and its distributor TuneCore. On September 9, CEO Mikey Shulman published the v6 launch post, describing v6 as a new generation of models developed with Warner Music Group, BMG and Believe, and stating that as v6 rolled out Suno would retire its previous models and move entirely onto the v6 generation. By the time Suno’s own v6 FAQ went up the same day, the wording had already changed from future tense to past: all models prior to v6 have been retired.

So the reason is not mysterious. The models that made Suno famous are the models named in the lawsuits. Keeping them selectable would have meant continuing to generate revenue from the exact thing Warner had sued over, after Warner became a partner. Retiring them draws a line: everything generated from now on comes from models the labels helped build and get paid for. As The Next Web put it in its launch coverage, the models trained on material Warner said was used without permission are being retired, and the replacements were developed with the same label that sued.

The Pressure Did Not Stop at Warner

Warner settling did not end Suno’s legal exposure, and I think that matters for understanding why the retirement was total rather than gradual.

Universal Music Group and Sony Music are still litigating against Suno in the US. Both have settled with Udio and struck licensing deals with it, but neither has settled with Suno as of this writing. There is a class action from independent artists, and a separate suit filed for Jason Isbell, David Lowery and others that skips copyright and argues Suno built a model that treats an artist’s name as a retrieval key for their voice and style.

Then there is Germany. On July 31, 2026, the Munich Regional Court ruled largely in favor of GEMA, the German collecting society, in its case against Suno. According to the analysis of the GEMA ruling by the law firm Bird and Bird, the court found that Suno’s models had effectively memorized six protected compositions and reproduced them in outputs, asserted jurisdiction over the training that happened in the United States, applied US copyright law to that training and rejected fair use, ordered Suno to stop, to disclose the scale of its use, and to pay damages. The judgment is not final and an appeal looks likely. But it landed six weeks before v6 shipped, and it was a court saying, in effect, that the old models were the problem. That is a strong incentive to stop offering them anywhere, including to US users.

A quick note for readers in the UK and EU, since the site’s frame is American law. The GEMA decision is German, not US, and Deadline reported that Suno does not expect it to affect the US cases. It does, however, signal that European courts are willing to reach across the Atlantic when outputs are served to European users. Separately, the EU AI Act’s transparency rules require machine readable markers in AI generated content, and Music Business Worldwide has noted that services already on the market before August 2, 2026 have until December 2, 2026 to comply. That is part of why watermarking and fingerprinting have been arriving alongside everything else.

What v6 Actually Is

Suno has never shipped a family of models before. Every earlier version was one model gated by plan. v6 is three.

According to Suno’s own descriptions, v6 is the flagship for Pro and Premier subscribers, built to be precise and consistent when you know what you want. v6-wild is also Pro and Premier only, and it is deliberately less predictable, meant to hand you textured and unexpected results you can then bring back into v6 to refine. v6-mini is the free model, and Suno claims it delivers better and faster results than any free model on any music platform. No benchmark accompanied that claim, and I would treat it as marketing until independent testing catches up.

The feature list is where v6 is materially different from what it replaced. Suno’s v6 FAQ lists the ability to edit one section of an existing song in plain language while leaving the rest intact, change a single lyric without regenerating the whole track, build a mashup from several sources in one request, sample and isolate an instrument and build a beat around it in one workflow, and prompt with text, audio, images and video together. There is a Variety slider that rewrites your style prompt to add unpredictability, and the FAQ says to set it to 0 if you want your style tags left alone. There is also a Max Mode that costs more credits and is meant for songs over two minutes, covers that need to stay close to the source, and keeping vocals consistent through a full track.

Credit costs did not change. A standard generation still produces two songs for 10 credits, though the FAQ notes that stuffing a prompt with images and video pushes the cost up. Pro is 10 dollars a month, or 8 dollars a month billed annually, for 2,500 credits. Premier is 30 dollars a month, or 24 dollars a month billed annually, for 10,000 credits and access to Suno Studio, the browser based DAW. Those are US list prices; the annual discount is the same 20 percent shape on both tiers.

What Suno has not said is what v6 was trained on. The launch post says the models were developed in partnership with the labels and that Suno has strengthened safeguards that screen uploaded audio and lyrics, but it does not describe the training set, and the artist payment structure for the opt in experiences it is teasing does not exist yet. The labels are in the product from day one. The artists are in a plan for later.

What Happens to the Songs You Already Made

This is the part that generated the panic, and it is the part where the actual policy is more reassuring than the headlines.

Nothing in your library is deleted. Suno’s August 10 FAQ on the upcoming changes is explicit: retiring a model means you cannot generate new songs with it, and it does not affect anything you have already made. Every existing song stays in your library, playable and shareable, exactly as it was. That holds on every plan, including free, and it holds if you cancel a subscription.

Files already on your hard drive are obviously untouched.

Where it gets more complicated is iteration. The v6 FAQ says you can keep working on songs made with older models, but any new iteration will be made with the latest models. Extend a v5 song and the extension is generated by v6. Cover it, and the cover comes out of v6. Remaster it, same thing. The original material is never modified, but the FAQ also says plainly that results may sound different from the original generation. A v5.5 track I extended on launch day came back with a noticeably different vocal timbre in the new section, and I ended up crossfading the seam in my DAW rather than fighting the model for a match.

Custom models get upgraded automatically so that v6 powers them going forward, and songs made with an old v5.5 custom model stay available and unchanged. Personas built on old model songs are the open question. Neither the August post nor the launch FAQ addresses what happens to a Persona’s voice consistency once its source material came from a retired model, and the newsletter writer at Roo’s Suno prompt pack publication flagged this as unresolved back in August. My advice is to assume the voice will drift and test before you promise a client continuity.

The Download Caps Are the Change That Actually Bites

If you are a hobbyist who mostly listens in the app, the model retirement is the whole story. If you release music, the download caps are the bigger deal, and they came from the same settlement.

Since September 3, 2026, according to Variety’s exclusive on the download caps, free accounts get up to 7 trial downloads for the lifetime of the account, for personal use only. Pro gets 20 downloads a month with commercial rights. Premier gets 60 a month with commercial rights. Premier subscribers working inside Suno Studio can download without limit. Monthly allowances reset on your billing date and unused downloads do not roll over.

The caps are retroactive. Suno’s FAQ states that download limits apply to all music on the platform starting September 3, including songs created before that date. A song you made on v4 in 2024 now costs a download to get off the platform, and if you are on the free tier that download is one of your seven and carries no commercial rights.

The counting rules are more generous than they first appear. One song is one download regardless of format, redownloading the same song does not count again, failed downloads do not count, and all the stems from a song are part of that song’s single download. Extra downloads will be purchasable, but as of this writing Suno has not published a price, which is the single number that decides whether this is a cap or a paywall.

Two more things from the new Terms of Service that Music Business Worldwide’s report on the download limits picked up on. First, the terms now prohibit obtaining a copy of an output by any means other than a Suno download channel, and they name recording and stream ripping specifically. Second, the practical effect of the new structure is that a song sitting in a paying subscriber’s library cannot be released, sold or licensed until a download has been spent on it. Downloading is now the step that unlocks commercial use.

My honest read is that the caps change my workflow far more than the model retirement did. I used to export every promising take to audition in the DAW. Now I audition in the browser, shortlist ruthlessly, and spend downloads only on keepers. At 2,500 credits and 20 downloads a month on Pro, the ratio is 25 generations for every export. For a solo artist finishing two or three tracks a month that is plenty. For anyone running a content channel or client work on Pro, it is tight, and Premier’s 60 is the realistic floor.

What the Retirement Does and Does Not Change About Ownership

This is the question I get asked most, so let me separate three things that people keep blending together: copyright, Suno’s commercial license, and infringement risk.

Copyright first, in the US frame. The US Copyright Office’s position has not moved because Suno swapped models. Its January 2025 report, Copyright and Artificial Intelligence Part 2 on copyrightability, concludes that AI outputs can be protected only where a human author determined sufficient expressive elements. Prompts alone, no matter how detailed or how many times you refined them, do not get you there. Human authored material that is perceptible in the output does, and so do creative modifications and arrangements of the AI material. If you registered a Suno song by disclosing the AI material and claiming only your lyrics, your added instrumentation or your arrangement, that registration is exactly as good today as it was in August. If you never had a copyrightable contribution in a v4 song, v6 did not create one. The model is irrelevant to authorship. Your hands are what count.

Second, Suno’s commercial license. This is what most people mean when they say they own their Suno songs, and it was never copyright. It is a contractual permission from Suno to use the output commercially, and it has always been tied to being on a paid plan when the song was made. The August FAQ confirms that any song you download as a paying subscriber carries commercial rights. The new wrinkle is that the download is now the moment those rights attach, which means a paid subscriber with a library of undownloaded v5 tracks should treat them as not yet cleared. Free tier songs have never had commercial rights, the seven trial downloads do not grant any, and downgrading to free later does not backfill rights onto songs you made while paying if you never downloaded them.

Third, infringement risk, which is where model retirement actually cuts both ways. The old models are the ones a German court found had memorized and reproduced specific compositions, and the ones still at issue in the Universal, Sony and class action cases. Suno retiring them does not retroactively clean the outputs they already produced. If a v4 or v5 track of yours happens to lean hard on a melody the model absorbed from a real record, that resemblance is baked into the file and no platform change fixes it. In practice the risk is low for the vast majority of tracks, but I would not release an old model song that gave me a nagging feeling of familiarity, and the more your release depends on income the more that caution is worth.

For readers in the UK and EU, one difference is worth stating plainly. The US analysis above turns on the Copyright Office’s human authorship requirement, which is a US rule. The EU position is now being shaped by rulings like GEMA v Suno, which treated memorized reproduction as infringement at the output level as well as during training. Do not assume the US analysis applies to a release you are making from London or Berlin.

There is one honest way to make the whole question go away, and I say this as someone who has done it for my own releases. If a Suno song is good enough that you want to build a catalog on it, have it re-recorded by real musicians. You write the parts, they perform them, and the resulting master is a human performance of a human arrangement with no Suno license attached and no retired model in its history. It costs more than a subscription and it is not the answer for a demo, but for a track you plan to pitch or promote it is the cleanest option on the table.

Can You Still Get the Old Sound Back

Suno’s official answer is yes. The v6 FAQ says the v6 family was designed to support all the ways people liked creating with past models, and it links a tutorial on how to achieve the results of your favorite past models. That is a workflow answer, not a fidelity answer. v6 is a different model with different training data and it will not reproduce v4.5’s particular grain or v5’s phrasing by request.

Two things I have found in the first days match what the early testers are reporting. The Hook Genius team, testing on launch day, made the point that the overwhelming majority of Suno prompting advice online was written for v4 or v5, and that much of it now describes behavior you cannot reproduce or even A/B against, because the old model is gone. Every metatag list and structure trick you saved needs re-testing, and the ones that relied on old quirks are dead. The style field is still 1,000 characters and the lyrics field 5,000, so the shape of a prompt is unchanged even if its contents need work.

The second is more encouraging. Jack Righteous, who publishes detailed model comparisons, reports that v6-mini sometimes produces the better keeper for a particular song than the flagship does. I have seen the same thing twice already on stripped back acoustic material. Do not dismiss the free model because it is the small one. Model choice is now part of the creative decision, and the right move is to run the same prompt through all three and listen before judging.

What I would not do is spend weeks chasing the exact texture of a retired model. That texture was partly an artifact of unlicensed training data. It is gone for reasons that will not reverse, and time spent recreating it is better spent rebuilding your prompt library around what v6 does well, which in my testing so far is arrangement coherence, vocal consistency across a full track, and honoring specific instrumentation requests.

What I Would Do This Week If I Had a Library of Old Songs

Start with an inventory, not a panic export. Go through your library and tag everything you would actually release, use in a video, or hand to a collaborator. For most people that is a much shorter list than the total, and it makes the download budget feel less like a wall.

Spend downloads on keepers only, and grab stems with them. Since a song and its stems count as one download, always take the stems bundle rather than the MP3 alone. Stems are what let you rebuild, remix, or replace parts in a DAW later, which is the only future proofing that survives platform changes.

If you are on Pro and have more than 20 keepers, do the math before buying anything. Premier is 20 dollars more per month and triples the cap. Extra downloads have no published price yet, and I would not commit to a plan based on a number Suno has not released.

Check the commercial status of anything already released. If you distributed a track through DistroKid, CD Baby or TuneCore while on a paid plan but never actually downloaded it from Suno, that is unlikely given you needed a file to upload, but confirm it. If a track went out from a free account, it never had commercial rights and it still does not, and the right fix is to pull it or replace it, not to upgrade and hope.

Re-test your three most important prompts on v6, v6-wild and v6-mini before you touch a client project, and set the Variety slider to 0 for the comparison so you are testing the model and not the slider.

If you registered songs with the US Copyright Office, nothing needs refiling. If you have not and the human contribution is real, do it now while your session notes and stems are fresh, because the deposit and the description of what you actually authored are what carry the claim.

Last, keep watching the Universal and Sony cases. The Warner settlement built the version of Suno we are using now, and a second settlement or a loss in court would reshape it again. Plan on the rules changing again.

Common questions

Why did Suno retire all its old models?

The retirement was a condition of the settlement that ended Warner Music Group's copyright lawsuit against Suno in November 2025. The joint release said that when new licensed models launched in 2026, the current models would be deprecated. The old models were trained on music the labels said was used without permission, and the v6 models were developed with Warner, BMG and Believe instead.

Are my old Suno songs deleted?

No. Every song you made on v4, v4.5, v5 or v5.5 stays in your library, playable and shareable, on every plan including free. Suno's FAQ says retiring a model only stops new generations with it and does not affect anything already made. Files you already downloaded are completely unaffected.

Can I still extend or cover a song I made on an older model?

Yes, but the new part is generated by v6. You can still use an old song as the starting point for an extension, remix, cover or remaster, and the original is never modified. Suno warns that the results may sound different from the original generation, and in my own testing the vocal character in a new section did not perfectly match the old one.

When were the old Suno models retired?

Suno launched v6 on September 9, 2026 and its FAQ published the same day said all models prior to v6 had been retired. The launch post used rollout language, but on accounts checked that day the model picker already listed only v6, v6 wild and v6 mini. Users had been warned in an email a few days earlier that came with 500 transition credits.

What are the three v6 models?

v6 is the flagship for Pro and Premier subscribers and is built for precision and consistency. v6 wild is also Pro and Premier only and is deliberately less predictable, meant for exploration. v6 mini is the free model available to everyone. Credit cost is unchanged at 10 credits for two songs per generation.

Did the Suno download limits come from the same settlement?

Yes. The Warner release in November 2025 said downloads would require a paid account and that paid users would get monthly caps. From September 3, 2026, free accounts get 7 lifetime downloads for personal use only, Pro gets 20 a month and Premier gets 60 a month, with unlimited downloads for Premier users working in Suno Studio. The caps apply to songs made before that date too.

Do I still have commercial rights to songs made on old models?

If you were on a paid plan when you made the song and you download it as a paying subscriber, yes. Suno's FAQ says any song downloaded by a paying subscriber carries commercial rights. Songs made on the free tier never had commercial rights, and the seven trial downloads do not grant any.

Does retiring the old models change whether I own the copyright?

No. In the United States, copyright in an AI assisted song depends on human authorship, not on which model generated it. The US Copyright Office says prompts alone do not create copyright, while human written lyrics, added parts and creative modifications can. A registration you made by disclosing the AI material and claiming your own contribution is just as valid now as before.

Can v6 recreate the sound of v4.5 or v5?

Not exactly. Suno says the v6 family supports the workflows people liked with past models and has published a tutorial, but v6 is a different model with different training data. Prompting advice written for older models needs re testing, and there is no way to A/B against the old model because it is gone. Some early testers have found v6 mini produces the better result on certain songs.

What should I do with my old Suno library right now?

Make a shortlist of songs you would actually release or use, and spend your downloads on those, taking the stems bundle since stems count as part of the same download. Re test your key prompts on all three v6 models with the Variety slider at 0. If a track matters enough to build on, consider having it re recorded by real musicians so the finished master has no platform license or retired model in its history.
