Best AI for generating music
For track generation, Suno holds the top score today and outperforms the rest on both independent music leaderboards. But there is a second axis no comparison page measures: whether the final file actually reaches the user at the end of the pipeline. Udio has blocked its download path entirely since October 2025, and Suno caps monthly delivery at between twenty and sixty files.
- five candidates under coverage, four with an active rank
- figures from two independent leaderboards
- a dedicated column for file delivery

Where each tool's score comes from
The ring below is the same set of weights printed in the table headers further down.
- Vocal quality 30
- Instrumental quality 20
- File delivery 20
- Track length 10
- Cheapest paid plan 10
- Access from Iran 10
We chose these weights, and that is the only judgment call in the table. Weight them differently and the order changes.
Today ranking, from published data and voted data
The first two columns are sourced from the Artificial Analysis music boards, which aggregate human votes; the remaining columns come from each vendor own documentation. An empty cell means no figure has been published, not that the value is zero.
| Rank | Tool | Score | Vocal quality 30 | Instrumental quality 20 | File delivery 20 | Track length 10 | Cheapest paid plan 10 | Access from Iran 10 |
|---|---|---|---|---|---|---|---|---|
| 1 | Suno Current pick | 66.7 | 1,171 Source: artificialanalysis.ai | 1,188 Source: artificialanalysis.ai | 1/3 | 480 seconds Source: help.suno.com | $8 per month Source: suno.com | not checked / no working route |
| 2 | Eleven Music | 62.5 | 1,069 Source: artificialanalysis.ai | 1,063 Source: artificialanalysis.ai | 2/3 | 300 seconds Source: elevenlabs.io | $5 per month Source: elevenlabs.io | blocked / no working route |

| 4 | Udio | 0.0 | 967 Source: artificialanalysis.ai | 954 Source: artificialanalysis.ai | 0/3 | 130 seconds Source: help.udio.com | not verified | not verified |
An empty cell means we could not verify that number, not that the tool scored zero.
Behind each number
Every judged score in this table carries a written reason, and the Iran column says how it was checked. Those two are open here. The measurement trail behind each number, which row of which leaderboard and on how many votes, opens under the model it belongs to.
1 Suno
File delivery 1/3 Download capability is implemented but rate-limited monthly: twenty files on the Pro plan, sixty on Premier, and zero on the free plan, parameters effective from the date the vendor itself records as 9/3/26
Access from Iran not checked / no working route Suno has published no supported-countries list, and no network measurement from inside Iran has been run, so this column registers as unknown. What is readable is the export-control clause in the vendor terms of service: it states the company headquarters is in the United States and that compliance with the user own jurisdiction is the user own responsibility. Payment processing runs exclusively through international cards.
Measurement trail (2)
Vocal quality 1,171 The Suno V5.5 specification holds first place on the vocals board with a measurement set of 9,982 samples, the version paid plans receive. The free plan runs on v4.5-all, which scores 1,089
Instrumental quality 1,188 The Suno V5.5 specification holds first place on the instrumental board with a measurement set of 5,995 samples, four points ahead of Mureka V9, a gap the confidence intervals of both measurements span
2 Eleven Music
File delivery 2/3 The output file is deliverable from both the app and the API with no monthly song ceiling defined; but consumption is metered in credit units (900 per minute), and separated-stem output has no specification anywhere in the documentation
Access from Iran blocked / no working route The only tool in this category whose vendor documentation explicitly names Iran. The export-control clause in the ElevenLabs terms has the user warrant they are not located in a country under US sanctions, and it lists Belarus, Cuba, Iran, North Korea, Russia, Syria and the annexed regions of Ukraine. That is a legal document, not the output of a network test; no measurement has been run from inside Iran.
Measurement trail (2)
Vocal quality 1,069 The Eleven Music v2 row, ranked ninth of fifteen on the vocals benchmark, based on 4,838 samples; the prior model version sits in its own separate, lower row as Eleven Music
Instrumental quality 1,063 The Eleven Music v2 row, ranked eighth of eighteen on the instrumental benchmark, based on 3,489 samples, the smallest sample size among the candidates in this table
3 Mureka
Measurement trail (2)
Vocal quality 1,162 The Mureka V9 specification holds second place on the vocals board, measured across 2,494 samples, with a 16-point confidence interval, the widest measurement band on the entire board
Instrumental quality 1,184 On the instrumental board, the Mureka V9 specification sits in second place, four points behind Suno, a ranking built on a measurement set of 2,421 samples
4 Udio
File delivery 0/3 Download capability for audio, video and stems has been disabled since 29 October 2025, a change recorded in Udio own support documentation; the generation pipeline still executes, but no file exits the service infrastructure
Measurement trail (2)
Vocal quality 967 The Udio v1.5 Allegro specification holds fourteenth place of fifteen rows on the vocals board, measured across 8,652 samples
Instrumental quality 954 The Udio v1.5 Allegro specification holds sixteenth place of eighteen rows on the instrumental board, measured across 4,708 samples
Not enough verified data to rank
These are real tools we track, but more than half of their criteria have no verified number yet, so ranking them would be a guess.
How this ranking is calculated
Every criterion below has a weight and a source. Change a weight and the whole table recomputes. There is no hand-placed position anywhere in this hub.
| Criterion | Weight | Evidence |
|---|---|---|
| Vocal quality | 30 | Music Arena (Vocals)Elo score on the Artificial Analysis vocals board, derived from blind pairwise comparison. It is the only point where the audio quality of these engines is measured; the Arena itself has no music board at all |
| Instrumental quality | 20 | Music Arena (Instrumental)The same measurement method, run on instrumental tracks. Kept separate because it is a distinct task and the ranking order shifts: Lyria sits fifth here and eighth on the other board |
| File delivery | 20 | defined scale, with a written reason per assignmentThe only ordinal criterion in this table: from zero (no download support at all) to three (uncapped download in multiple formats plus separated stems, across every plan). Each step is extracted directly from the vendor own documentation |
| Track length | 10 | vendor stated specificationThe longest track produced in a single generation run, from the vendor own official guide. No figure at all is published for Flow Music |
| Cheapest paid plan | 10 | vendor stated specificationA lower figure scores higher. The baseline is the monthly rate under annual billing, since all three vendors that publish a price headline that figure. Udio publishes none |
| Access from Iran | 10 | our access column, with its method statedOnly one candidate carries a citable document in this column. An empty cell means no document has been read, not a guess |
Why Suno leads
Because at both points where its audio quality has been measured, it stands above the rest: 1,171 on vocals and 1,188 on instrumental, against 1,069 and 1,063 for Eleven Music and 967 and 954 for Udio. It also produces the longest track: eight minutes in a single generation run.
One caveat this audit adds itself: on the instrumental column, its margin over Mureka is only four points, while the confidence intervals of both rows span nine and sixteen points respectively. That means the two engines are effectively at parity, and "first place" on that column is not a firm claim. On the vocals column the margin is nine points, which holds up better.
An axis no other comparison measures
The delivery column was built because researching this category surfaced a finding logged in no other comparison anywhere: since 29 October 2025, coinciding with its deal with Universal, Udio has fully disabled the download path for audio, video, and stems, and states this in its own documentation. Its paid subscription generates tracks but delivers no file to the user.
Suno also caps output, but the constraint type differs: twenty downloads a month on the Pro plan and sixty on Premier, while those same plans provision 2,500 and 10,000 generation credits respectively. That means you generate hundreds of times and take delivery sixty times. At the top of this column sits Google Flow Music, which delivers mp3, wav, and m4a output plus separated stems on all four of its plans, including the free one.
And because normalization runs across the full candidate set before ranked entries are separated from unranked ones, the ceiling of this exact column was set by the very Flow Music entry that carries no rank of its own.
Why Google Flow Music remains unranked
Because two of the six columns in this table are empty for it, and the combined weight of those two columns exceeds half the table. Google has stated nowhere what the maximum length of a Flow Music track is, and the model it presents on its homepage is Lyria 3.5, a model with no independent row on any leaderboard.
The Lyria 3 Pro figure could have been borrowed in its place. That was not done, because that is an API model and this is a consumer product, and the same principle was upheld in the chat category for a sibling model. If Google publishes a track length tomorrow, or Lyria 3.5 enters a leaderboard, this engine will likely land near the top of the table; today it simply lacks the recorded data.
Mureka, a name unheard of in Iran
It holds second place on both leaderboards, ahead of Lyria, Eleven Music, and Udio. Yet not one figure could be extracted directly from the vendor itself: mureka.ai has no page titled pricing, and its API platform returns an empty response body. Even its version name, V9, is taken from the leaderboard rather than from its own official source. As a result it forfeits half the available weight in this table and still holds third place.
This status is deliberately documented, because dropping it silently would have been simpler but inaccurate. Any comparison published without Mureka in it is likely just repeating what everyone else already publishes.
Two axes deliberately excluded from the table
First, monthly output volume. Suno provisions 2,500 and 10,000 credits without stating the credit cost per track; Udio provisions 2,400 and 6,000 credits and does publish its rate (two credits per 130-second track); Flow Music annotates its 3,000 credits with an estimate of roughly 600 tracks; Eleven Music charges 900 credits per minute. Four different units with no conversion path between them. A column holding four unrelated figures is not a valid measurement column.
Second, commercial usage rights. Eleven Music is the most explicit and states its output is cleared for nearly all commercial uses; Suno grants commercial rights only on paid plans; no documentation was found for Udio or Flow Music. A column with three empty cells only penalizes vendors that have published less data. This axis is addressed in the prose, not in the scoring table.
Persian
None of these five engines publishes the list of languages it sings in. Eleven Music states "English, Spanish, German, Japanese, and more," which is not a citable list, and Suno own site is localized into fourteen languages, none of them Persian. So which engine sings Persian best is data that is not in hand, and no claim is made about it. If Persian output is required, direct testing on the free plan is the only reliable method, and it is the one recommended here.
When our top pick is not the right fit
- If you need a Persian lyric with correct pronunciation, this table has no answer: no vendor publishes a language list.
- If you want to integrate music generation directly into your own software, skip this table and use the API model, whose per-track pricing is transparent.
- If all you need is one instrumental background bed for a video, the cheapest row is sufficient and moving up the table is unnecessary cost.
Known weaknesses and limits
- Audio quality comes from a human voting board, not from independent testing here; these five engines have not been run against one identical prompt for comparison.
- The Udio price cell is empty in the table because its pricing page does not render for our infrastructure.
- Google Flow Music remains unranked because neither its track length is published nor does its model carry a row on any leaderboard.
- Mureka forfeits half the measurable weight of the table because it publishes no citable figure of its own.
- The Iran access column carries a document for only one candidate; the rest are logged as unknown.
- Monthly output volume and commercial usage rights carry no dedicated columns; the rationale is documented above.
Technical verdict
For a track that is itself the final deliverable, Suno is the right pick; count how many files you need per month before purchasing. For music under video and podcasts, where you may later need to prove usage rights, Eleven Music holds the cleanest legal position. And if separate files and stems are the deciding axis, Flow Music is the only engine that delivers this even on its free plan, though no figure yet exists for measuring it independently.
Frequently raised questions, with documented answers
What is the best AI music generator
Suno, based on two independent human voting boards that measure audio quality across these engines. But if your workload is file delivery to clients, check its monthly download cap before purchasing.
Why can you not download tracks from Udio
Because since 29 October 2025, coinciding with its deal with Universal, the download path for audio, video, and stems has been disabled. Udio own help center documents this.
Which AI generates music in Persian
None of these five engines publishes the list of languages it sings in, so no claim is made either way. The only reliable method is direct testing on the free plan.
What is the cheapest way to get started
Flow Music and Eleven Music both start at around six dollars a month. The key difference: the ElevenLabs free plan generates no music at all, while Flow Music supports downloads even on its free plan.
