AI Music Generator Test: 7 Models Compared, Prices & Results

👁 129 reads

An AI music generator creates complete tracks from style descriptions, and the best ones also work with your own lyrics. For vocal songs in October 2026, the main players are Suno, Eleven Music, Google Lyria 3.5 (Gemini and Flow Music), and MiniMax Music. Udio disabled downloads, and Stable Audio 3 only does instrumentals. We ran the same Polish lyrics through 7 models and measured which ones actually sing in Polish - all recordings are below.

What Is an AI Music Generator

It’s a model that turns a description (“melancholic synth-pop, male vocal, 108 BPM”) into an audio recording. Tools fall into three groups, and your choice depends on what you need:

• Songs with vocals and lyrics - Suno, Udio, Eleven Music, Lyria 3.5, MiniMax Music, Mureka. You type in lyrics, the model composes a melody and sings.
• Instrumental backing tracks - Stable Audio 3, AIVA, Mubert, Soundraw, Beatoven. Music for videos, games and podcasts, no singing.
• Open models you can run yourself - ACE-Step 1.5, DiffRhythm, YuE, HeartMuLa. Free, but they handle Polish poorly, as you’ll see in our test.

We covered what these tools can do and who owns the output in our article AI for music, and how to write lyrics for AI models in the guide How to write song lyrics for AI.

How to Start: Your First Song Step by Step

1. Choose a tool based on your goal: song for publishing - Suno or Eleven Music, short jingle for video - Eleven Music, playing around in an app - Gemini with Lyria 3.5, background without vocals - Stable Audio or AIVA.
2. Write your own lyrics. 8-16 lines, mark sections with [Verse] and [Chorus]. Short, regular lines (8 syllables in our test) come out cleaner.
3. Write the style description in English, but keep your lyrics in your language. Add explicitly “vocal singing in Polish, clear diction” if testing in Polish.
4. Specify tempo in BPM, instruments and voice type. Set length with a parameter if the tool has one.
5. Listen with the lyrics in front of you and mark words that sound wrong. Usually it’s consonant clusters - in our test “z Gdańska” and “drżą“.
6. Before you publish, check the plan: does it allow downloads and commercial license. In Udio you get neither.

Top Generators in October 2026

Suno

The most popular song generator. Since September 9, the v6 family is live: v6 and v6-wild on Pro and Premier plans, v6-mini for everyone, up to 8 minutes per generation. The model was trained on licenses from Warner, BMG and Believe. Since September 3, download limits apply: 20 per month on Pro, 60 on Premier, free plan doesn’t allow downloads. Premier also includes Suno Studio 2.0, a browser-based editor with stem export. Suno isn’t available through API, so it didn’t make it into our test. More: Suno, Suno v6 and Suno AI in Polish.

Udio

The second pioneer, founded by former Google DeepMind researchers. After settling with Universal Music Group on October 29, 2025, it disabled downloads on all plans. The latest model is v1.5 Allegro from March 2025. Udio is announcing a licensed Starstruck app where tracks will stay in a closed ecosystem. Udio has no public API, so we didn’t test it. Everything about the service is in our guide Udio.

Eleven Music (ElevenLabs)

Music v2.5 launched September 11, 2026. Tracks from 3 seconds to 5 minutes, vocal or instrumental version, section-by-section composition plan and fragment inpainting. Commercial license from Starter plan, API at $0.15 per minute. It won our test. Separate test: Eleven Music with Polish lyrics.

Google Lyria 3.5, Gemini and Flow Music

Google has two entry points. The Gemini app creates tracks up to 3 minutes with Lyria 3.5 (since September 4, 2026, adults only). Flow Music is the former Riffusion, then ProducerAI, which Google bought in February and renamed in April 2026. It has MP3, WAV and stem downloads. Lyria’s official language list doesn’t mention Polish, yet in our test both Lyria 3.5 and 3 Pro sang all 8 verses. Launch context: Lyria 3.5 in Flow Music.

MiniMax Music

Chinese company MiniMax (the one behind Hailuo video) has Music 2.6 from April and Music 3 from July 2026, with open weights since August. Up to 5 minutes per track. It sings Polish intelligibly but with a noticeable foreign accent. About the company: Hailuo AI and MiniMax.

Mureka

Generator from Chinese company Kunlun, currently model 9.5 (version from August 28, 2026 in API changelog). Official FAQ lists 10 singing languages - Chinese, English, Japanese, Korean, Portuguese, Spanish, German, French, Italian and Russian. Polish is not on the list.

Stable Audio 3

Stability AI released four models on May 20, 2026, including Medium with open weights (tracks up to 6:20). Trained on licensed data, results belong to the user, companies with revenue over $1M need a license. No model sings - this is a tool for backing tracks and effects.

Open Models

ACE-Step 1.5 (MIT license, less than 4 GB VRAM, claims 50+ languages), DiffRhythm (Apache 2.0, tracks up to 4:45), YuE and HeartMuLa. You can run them on your own GPU for free. On fal.ai we tested ACE-Step and DiffRhythm - Polish lyrics fell apart in both.

Our Test: Same Polish Lyrics in 7 Models

We wrote a short song - verse and chorus, 4 lines each, 8 syllables per line. We deliberately included words that trip up foreign models: “z Gdańska“ (from Gdańsk), “drżą“ (they tremble), “szczęście“ (happiness), “zamieć“ (blizzard), “zmieścić“ (to fit). We described the style in English, identically for each model: melancholic synth-pop, male vocal singing in Polish, warm synthesizers, 108 BPM, night train mood.

[Verse]
Nocny pociąg z Gdańska rusza
szyby drżą od zimnych świateł
piszę do ciebie dwa słowa
żadne z nich nie chce się zmieścić
[Chorus]
Jeszcze jedna stacja, jeszcze
szczęście świeci mi przez zamieć
nie odpisuj, będę rano
zanim miasto się obudzi

Translation: [Verse] Night train from Gdańsk is leaving / windows tremble from cold lights / I’m writing you two words / neither of them wants to fit / [Chorus] One more station, one more / happiness shines through the blizzard / don’t reply, I’ll be there in the morning / before the city wakes up

How we measured:

• We generated all tracks on October 3, 2026 through fal.ai API, each model once. We didn’t cherry-pick the best of several attempts.
• We separated vocals from music with Demucs model, then transcribed with Whisper large-v3 (three passes: vocals only, vocals with silence filter, full mix). For each line we took the best match.
• We counted words recognized without error (out of 39) and verses recognized at least 80%.
• A second opinion came from Gemini 3.8 Flash, which we asked to rate pronunciation alone on a 1-5 scale, like a vocal producer would.

Audio Samples

Results: Polish Pronunciation

What this shows:

• Eleven Music sang all 39 words flawlessly and was the only model without any mistakes. This matches our earlier test where it got 37 out of 37 words. However, it’s the most expensive through fal.ai - $0.60 per minute, four times more than directly through ElevenLabs API.
• Lyria 3 Pro and 3.5 are the biggest surprise. Google doesn’t list Polish among supported languages, yet both models sang all verses with minor errors. Lyria 3 Pro cost $0.08 for over a minute of music.
• MiniMax sings intelligibly but with an accent. Both models failed the same first verse - the cluster “z Gdańska rusza“ came out garbled. The chorus, phonetically simpler, was clean.
• Open models fail at Polish. ACE-Step fakes Polish without words, DiffRhythm sings meaningless syllables. They might work for instrumentals, not for Polish songs.
• Difficult words: “Gdańska“ and “drżą“ caused problems in at least two models, “szczęście“ and “zamieć“ in one. If you need clean diction, avoid consonant clusters at the start of the track.

Caveat: this is one attempt per model, one set of lyrics and one genre. Gemini’s rating is automatic and in several places more lenient than the transcription. Suno and Udio have no public API, so we couldn’t run them under the same conditions.

Comparison: Which Generator for What

Which Generator for Whom

• Polish song for publishing: Suno (most control over the track, download limit) or Eleven Music (cleanest Polish in our test, commercial license).
• Jingle, podcast intro, ad: Eleven Music - short forms in seconds and reliable diction.
• Cheap through API: Lyria 3 Pro on fal.ai - $0.08 per track with very good Polish.
• Playing around without paying: Gemini app with Lyria 3.5 or free Suno.
• Backing track without vocals: Stable Audio 3, AIVA or Mubert.
• Don’t choose Udio if you need a file. Without downloads you can’t do anything with the track except listen in the service.

Frequently Asked Questions

What is the best AI music generator?

For songs with vocals, Suno v6 is most commonly chosen. In our Polish pronunciation test, Eleven Music performed best (39 out of 39 words), closely followed by Lyria 3 Pro and 3.5 from Google.

Yes. Suno gives 50 credits daily, Udio 10 credits daily, Gemini creates tracks with Lyria 3.5 in the app, and ACE-Step and Stable Audio 3 Medium can be run free on your own computer. Free plans usually don’t allow downloads or commercial use.

Which AI music generator sings in Polish?

In our test from October 3, 2026, we tested in Polish and found that Eleven Music, Lyria 3 Pro, Lyria 3.5 and both MiniMax models sang intelligibly. ACE-Step and DiffRhythm didn’t sing Polish lyrics. Suno also sings in Polish - how to improve pronunciation is described in Suno AI in Polish.

Can you use AI music commercially?

Depends on the plan. Suno gives commercial rights on Pro and Premier, Eleven Music from Starter plan, Stable Audio under Community license for companies up to $1M revenue. Udio restricts output to personal use and doesn’t allow downloads.

Is Udio better than Suno?
