Suno vs Udio: Which AI Music Generator to Use

Type a genre, a mood, and a few lines of lyrics into either Suno or Udio, and 30–60 seconds later you have a full song — verses, chorus, vocals, instrumentation, mixed and mastered. Both got there the same way: by training on recorded music at a scale the major labels say was never licensed, which is why both companies are still being sued over it, and why that lawsuit’s outcome now differs meaningfully between them. This page covers what each product costs, what “commercial use” currently means on each one now that the legal picture has partly resolved, and — because this changed nine months ago and again three days before this page was written — whether you can even download the song you made.

How they work, in practice

Both are prompt-in, song-out tools with the same basic flow: describe a genre and vibe (or pick style tags), write or auto-generate lyrics, and generate. Both let you extend a track, remix sections, separate stems, and — on paid tiers — train on a reference voice or your own back catalog to steer the sound. Neither requires any music-production knowledge to get a finished-sounding song.

Suno runs on its own numbered model line, currently v5.5 (shipped 26 March 2026), with “Voices” (record or upload your own singing voice and Suno performs on top of it), “Custom Models” (Pro/Premier subscribers can train a personal model on at least 6 uploaded tracks), and a “My Taste” personalization layer [1][2]. It also ships Suno Studio, a DAW-style editor with MIDI, automation, and stem-level mixing, gated to the Premier plan.

Udio runs on v1.5 plus a faster Allegro v1.5 variant — both released in 2024–2025, and as of this writing no successor model has shipped, though the company has signaled a next-generation model tied to its new licensing deals for later in 2026 [3][4]. Udio’s distinguishing features are audio-to-audio remixing (upload existing audio and transform it), inpainting (regenerate just a section of an existing track), and Sessions, a chat-style iterative refinement workflow.

Pricing and limits

Suno’s numbers come directly from its own pricing page [1]; Udio’s official pricing page renders its plans client-side and blocked automated fetching, so the figures above are cross-checked against several independent trackers that agree closely with each other [5]. Both companies sell add-on credit packs that don’t expire, separate from the monthly allowance that does. On both platforms, one credit is roughly one short generation, and a full-length track costs more — neither publishes the exact multiplier, so your effective “songs per month” will run lower than the headline math once you’re picking favorites out of several takes.

The download question — this is the part that actually differs right now

This is the single fact most likely to change which tool is right for you, and it changed very recently on both sides.

Suno introduced new download caps on 3 September 2026 — the day before this page was last verified. Free accounts now get 7 lifetime downloads total, Pro subscribers get 20 a month, and Premier subscribers get 60 a month (Premier’s Suno Studio exports are uncapped). Suno’s stated reason is to make it “harder for bad actors to mass-export” music at scale [6][7]. Spending a download is now the actual mechanism for getting a paid-tier song off Suno and onto a streaming platform — you can generate as many songs as your credit balance allows, but only as many as your download cap allows leave the platform as a usable file.

Udio’s downloads have been off entirely since 30 October 2025, and they still are. When Udio signed its settlement and licensing partnership with Universal Music Group, it disabled downloading for every user — free and paid — as part of that deal; a user backlash got the company to open a one-time 48-hour recovery window (3–5 November 2025) so people could pull down songs they’d already made, and then downloads closed again [8][9]. Udio’s own help center confirms the current state plainly: “downloading of audio, video, and stems has been disabled” [10]. The company says the product is being rebuilt into a closed, streaming-only platform — create and listen inside Udio, but don’t count on taking the file anywhere else once the relaunch lands, with no date published as of this writing.

Practically: if getting a finished audio file out of the platform — for a distributor, a video, or just to keep — is the point, Suno lets you do that, on a per-download budget. Udio does not let you do that at all right now, on any plan.

Commercial rights and ownership, by plan

Suno, straight from its Terms of Service [11]: on a paid plan (Pro or Premier), Suno “assigns to you all of its right, title and interest” in songs you generate, usable commercially — sell, stream, sync — provided you obtained the track through a permitted download under your tier’s cap. On the free tier, Suno keeps ownership and you’re contractually restricted to “lawful, personal and non-commercial purposes” only. This isn’t retroactive: starting a paid subscription later doesn’t grant commercial rights to songs made while on Free. Suno also keeps a broad license to use anything you generate for training, promotion, and product improvement, on both tiers.

Udio, per its help center [12]: Udio states it doesn’t claim ownership of what you generate, and content can be reused commercially as long as it doesn’t contain copyrighted material you don’t have rights to. The tier difference is attribution, not rights: free users must credit Udio when reusing content commercially; paid subscribers aren’t required to. But with downloads disabled platform-wide, “commercial rights” on Udio right now is a legal permission with no working mechanism to exercise it outside Udio’s own player — you own the right to use a song you can’t currently get a file for.

The lawsuit both of you have heard about — current status

Universal Music Group, Sony Music, and Warner Music Group, coordinated by the RIAA, sued both Suno and Udio in June 2024 for training on copyrighted recordings without a license, seeking damages of up to $150,000 per work [13]. As of September 2026, that single lawsuit has split into a genuinely different legal position for each company:

Udio has settled with two of the three majors: Warner Music Group (19 November 2025) and Universal Music Group (29 October 2025), both converting into licensing partnerships and a rebuilt, catalog-approved AI platform rather than continued litigation [8][14]. Sony Music has not settled. A judge denied Sony’s mid-2026 bid to add over 30,000 recordings to its existing 333-recording suit — but instead of dropping the point, Sony turned around in July 2026 and filed a second, separate infringement suit against Udio reasserting those same 30,000-plus recordings [15][16]. So Udio currently faces two active Sony Music lawsuits, not one narrowed one.

Suno’s position is also unresolved, and arguably worse. Warner Music Group settled with Suno on 25 November 2025, a deal that also gave Suno ownership of Warner’s Songkick platform [17]. BMG signed a global licensing deal on 12 August 2026 — BMG had never sued Suno; this was a straight licensing agreement [7][18]. But Universal Music Group and Sony Music are both still litigating against Suno in the US, in a Boston case the labels moved in 2026 to expand from roughly 560 to over 61,000 recordings, pushing potential statutory damages past $9 billion; talks reportedly hit an impasse in April 2026 over UMG and Sony wanting equity stakes and higher per-stream guarantees than Suno gave Warner [19][20]. Suno also faces three newer suits: a $66.6 million copyright claim from Latin label Gerencia 360 (filed 31 August–1 September 2026) [21]; a class action led by musicians Jason Isbell and David Lowery (filed 31 August 2026) alleging Suno lets users generate songs that mimic a named artist’s voice and style — a right-of-publicity claim distinct from the copyright case, which Suno has called “without merit” [22]; and a copyright suit from Canada’s SOCAN collecting society (filed 2 September 2026, two days before this page’s last verification) alleging Suno’s outputs reproduce songs like “Both Sides Now” and “Sk8er Boi” almost note-for-note [23].

And outside the US, Suno has already lost once: Germany’s GEMA won its infringement case against Suno at the Munich Regional Court on 31 July 2026 — widely reported as Europe’s first major court ruling on AI music, and a direct finding that training on protected recordings without a license is infringement [24]. Denmark’s Koda filed a similar suit in Copenhagen City Court in November 2025 that’s still pending. Neither Udio nor the RIAA-coordinated US case has produced a final ruling on the merits yet; Suno’s GEMA loss is the closest either company has come to an actual court verdict, not just a settlement.

One more thread: the American Federation of Musicians sued Universal and Warner directly in mid-2026, arguing that licensing performers’ recordings to Suno and Udio without individually notifying or compensating those performers breaches the labels’ own union agreements — a sign the “resolved” settlements haven’t settled whether the artists on those recordings were made whole [25].

What this means for you: neither company is “cleared.” Using either tool, for a hobby project or commercially, means using a product built by training on music the industry says wasn’t licensed, and that dispute stays open with at least one major label against each company — plus, for Suno specifically, a completed loss in a German court and two additional collecting-society suits (Canada, Denmark) outside the US case entirely. The settlements reduce but don’t eliminate that exposure, and say nothing about the newer publicity-rights, union, and international claims.

AI music on Spotify and other streaming platforms

AI-generated tracks are already on every major streaming service, at a scale that’s become the platforms’ own problem, not just a music-industry one. Deezer reported fully AI-generated tracks at 44% of daily uploads (~75,000 tracks/day) in April 2026, rising past 50% by June 2026 — around 90,000 AI tracks a day [26]. Spotify said in September 2025 it had removed over 75 million “spammy” AI-generated tracks over the prior year and introduced new policies: an updated spam filter, a ban on unauthorized AI voice clones, and standardized AI-disclosure fields in track credits — the same 75-million figure was still being cited in coverage as late as July 2026, suggesting the platform hadn’t published an updated count as of this writing [27].

Spotify separately rolled out an “AI Persona” label starting 11 August 2026, letting artists self-disclose an AI-generated identity, backed by human review and detection tools when they don’t; AI Persona profiles are excluded from editorial and algorithmic recommendations by default. The nuance: this label tags the artist’s identity, not the song’s production method — a human musician who used Suno or Udio to write a track doesn’t get flagged, and there’s currently no platform-wide “this track was AI-generated” tag separate from the artist-identity label [28]. Both companies are also deploying their own watermarking and fingerprinting (Suno partners with Audible Magic and Musixmatch’s Sentinel system) so distributors and platforms can detect AI origin at upload [7].

Neither Suno nor Udio distributes to Spotify directly — you still need a third-party distributor (DistroKid, RouteNote, TuneCore) to get a track onto streaming platforms, one more reason Udio’s no-downloads state matters more than it first appears.

Who should pick which

Pick Suno if you want the more capable, actively developed model and need to actually export finished audio files today — for a distributor, a video, or just to keep — and are fine working within a monthly download cap. It’s also the pick for training a custom model on your own catalog or singing on your own generations via Voices, neither of which Udio offers.

Pick Udio if you specifically want its remix/inpainting workflow and more granular section-by-section editing, and you’re fine using it as a create-and-listen sandbox rather than a source of exportable files, at least until its promised relaunch ships with a defined download policy.

If you need commercial output today, Suno is the workable option: an actual file, with real commercial rights on a paid plan, subject to your download cap. Udio’s commercial-use language is arguably cleaner on paper — no attribution requirement, broader stated rights — but it’s currently unusable in practice because there’s no way to get the file off the platform.

If the ongoing lawsuits change your calculus — say you’re building a business around AI-generated music rather than a personal project — treat neither company as legally settled, and weigh Suno’s exposure as the larger of the two. Suno has active, expanding US litigation from two of the three major labels with damages claims in the billions, three newer suits filed in the days around this page’s publication (Gerencia 360, Isbell/Lowery, SOCAN), and an actual courtroom loss to GEMA in Germany in July 2026 — the first ruling either company has taken on the merits. Udio has two active Sony Music suits and an unresolved question, via the AFM litigation, about whether the artists behind its now-licensed training data were actually compensated. Expect that legal cloud to lift slowly, not resolve cleanly, over the next year or more.

Casual, no-stakes use. Either free tier works to try this out — Suno’s gives you a slightly older model with a 7-download lifetime cap; Udio’s gives you its current model with no downloads at all. Trying both costs nothing but ten minutes.

What this page can’t settle for you

Exact “songs per credit” conversion rates aren’t published by either company and vary by generation length, so budget your monthly plan with some slack. Udio’s next-generation model and platform relaunch have no announced date — check udio.com/blog before assuming the current download-free state is permanent. And whether the still-open Suno/UMG/Sony litigation or the AFM’s compensation lawsuit poses real risk to your specific commercial use is a legal question this page states facts about but doesn’t resolve — talk to a lawyer before building a business on either platform’s output.
