Best AI Music Generators 2026: Suno v6, Mureka & Eleven Music

👁 131 reads

According to the independent Artificial Analysis benchmark as of October 2026, the best AI music generator is Suno v6, scoring 1142 Elo in vocal tracks and 1140 in instrumental music. Suno v6-mini takes second place, followed by Mureka V9.5 in third. In our hands-on pronunciation benchmark testing non-English lyrics in Polish, Eleven Music v2.5 delivered the cleanest vocals, while the open-source ACE-Step 1.5 proved to be the top locally runnable model.

This comparison combines two datasets: blind human listening tests from Artificial Analysis and our hands-on measurement of how effectively these models handle complex non-English vocal synthesis. For our broader software breakdown, see our guide on AI music generators, and catch the leaderboard breakdown in Suno v6 leads, Mureka V9.5 follows.

Artificial Analysis Leaderboard: Vocal and Instrumental Elo

Artificial Analysis plays pairs of generated tracks created from identical prompts to blind human evaluators, asking them to vote on the superior track without knowing the underlying model. From thousands of these pairwise votes, it computes an Elo-style rating. In version 1.1, scores reflect a vetted human listener panel rather than a public crowdsourced arena. The baseline is MiniMax Music 3.0, calibrated at 1000 Elo. Tracks average around 3 minutes, and for vocal generations, the model writes its own lyrics based on the style prompt (methodology).

Source: AA-Music-Vocal v1.1 and AA-Music-Instrumental v1.1, recorded October 8, 2026. The table omits Eleven Music v1 (1001 and 1021), MiniMax 2.5+ (987 and 1005), and Stable Audio 2.5 (986).

Key takeaways from the leaderboard:

• Confidence intervals hover around ±15 points. Mureka V9 and Lyria 3.5 sit tied at 1052 in vocals, while Mureka V9, V9.5, and both Lyria versions all land between 1076 and 1081 in instrumental - forming a statistical tie across ranks 3 through 6.
• Suno v6 holds a clear lead. Outperforming its mini variant by 26 points and Mureka V9.5 by 39 points in vocal generation represents a lead that exceeds the margin of error.
• Mureka V9.5 marks the steepest jump: gaining +51 points over V9 in vocal performance, while both Mureka releases perform almost identically in instrumental tracks.
• The leaderboard primarily evaluates English or model-selected languages. It provides no signal on non-English pronunciation, which prompted our hands-on phonetic test.
• Udio does not appear in the rankings. Since October 2025, Udio has barred song downloads entirely (read our full overview in what is Udio).

Hands-on Vocal Test: Same Lyrics Across Four Models

We wrote a custom short song titled “Morning in Łódź” to test challenging non-English phonetics: 2 verses and a chorus, 12 distinct lines, 52 words, full of difficult consonant clusters and sibilants. Because testing foreign language pronunciation reveals how well a model handles complex phonetic sequences, we tested it in Polish. With the chorus repeated twice, the full track contains 69 words to be sung. Every model received the identical style prompt in English: “nostalgic indie pop ballad, warm female vocals singing in Polish with clear diction, acoustic guitar, piano, brushed drums, 96 BPM.”

The test lyrics:

• Verse 1: Rano w Łodzi pachnie deszczem / tramwaj dzwoni pod oknami / piszę listy, których nie wyślę / i chowam je między książkami (“Morning in Łódź smells like rain / a tram rings under the windows / I write letters I won’t send / and hide them between books“)
• Chorus: Zostań ze mną do jutra / niech ten świat chwilę poczeka / szepczesz moje imię / jak piosenkę z daleka (“Stay with me until tomorrow / let this world wait a moment / you whisper my name / like a song from far away”)
• Verse 2: Wieczorem nad Wisłą cicho / most się żarzy jak zapałka / w kieszeni szeleszczą bilety / i pognieciona kartka (“Evening by the Vistula is quiet / the bridge glows like a match / tickets rustle in my pocket / and a crumpled piece of paper”)

Our testing methodology:

1. Each model generated the track twice on October 8, 2026.
2. We separated vocals using Demucs (htdemucs), then transcribed lyrics with Whisper large-v3 across three passes: vocals only, vocals with a silence filter, and the complete mix. For each line, we took the highest-matching transcript and counted error-free words (2 runs × 52 words = 104 words total).
3. We also calculated “word sequence alignment”: what percentage of the full 69 words appeared in the intended order, penalizing dropped choruses or rearranged verses.
4. Full audio tracks were evaluated by two audio-capable LLM judges via OpenRouter: Google’s Gemini 3.8 Flash and Alibaba’s Qwen 3.8 Omni Flash, rating pronunciation, audio fidelity, style adherence, and musicality on a 1-5 scale. Note: Because Lyria is a Google model, treat Gemini’s rating of Lyria with appropriate caution.

Scores from 1-5 represent the average across 2 runs and 2 judges (4 ratings per model).

Key observations from the test:

• With a well-crafted prompt, all four models produce intelligible non-English vocals. Whisper transcribed 97-99% of words without error. Nuances came down to edge cases: ACE-Step rendered noc się żarzy instead of most się żarzy, MiniMax distorted two words, Lyria shifted one vowel slightly, and Eleven swapped an initial consonant on one word.
• Eleven Music v2.5 came out on top. Both judges gave it a unanimous 5/5 for pronunciation across all evaluations, with Qwen noting that run 2 sounded like a professional studio release. Drawback: with an 85-second track limit, run 1 truncated the second chorus (dropping sequence alignment in that take to 75.4%).
• Lyria 3 Pro followed style instructions best (4.8 out of 5), though judge Qwen detected a slight foreign accent on heavier sibilant clusters.
• MiniMax Music 3 sang the text, but missed the mood. Gemini noted in both runs that instead of an intimate indie ballad, it generated an exaggerated musical theater routine. Run 2 lasted only 54.5 seconds, rushing through the text far faster than requested.
• ACE-Step 1.5 was the biggest surprise. On October 3, the earlier ACE-Step release on fal.ai correctly sung only 8 of 39 words. Version 1.5 running locally reached 101 out of 104 words and averaged 4.5/5 on pronunciation.

Generation Speed and Cost per Song

Cold loads on local hardware take longer because models were loaded from an external USB drive (~44 MB/s). On an NVMe SSD, initial setup is significantly faster, and subsequent iterations take seconds.

Instrumental Backing: Stable Audio 3 Medium

Because Stable Audio does not render vocals, we evaluated it separately: two 60-second backing tracks in the same indie pop style, plus a 30-second uptempo track for video reels. The judges averaged: fidelity 4.0, style adherence 4.6, musicality 4.0. Gemini gave the first backing track 4.5-5, while Qwen noted a slightly boxy drum sound and repetitive guitar phrasing on the second sample.

Omissions and Test Constraints

• Suno v6 lacks a public API, preventing an identical automated measurement pipeline. For our hands-on Suno analysis, visit our hub on Suno and our guide to multilingual prompts in Suno.
• Mureka V9.5 offers an API, but requires a registered account and a $10 trial credit pack. On fal.ai it costs $0.225 per vocal generation, but our fal.ai account was inaccessible on test day. Mureka officially lists support for 10 languages, excluding Polish.
• Lyria 3.5, MiniMax Music 2.6, and MiniMax Music 3 in the cloud were tested on October 3 with a 39-word lyric set: Lyria 3.5 hit 36, MiniMax 2.6 hit 34, and MiniMax 3 hit 32 words.
• Two runs per model represent a small sample size, and LLM judges exhibit subjective variance: on the exact same ElevenLabs track, Gemini awarded a 2/5 for style (flagging the cut chorus), while Qwen gave it a 5/5.
