A comparison of Suno v6, Udio, Stable Audio and Mubert, with pricing and commercial rights as of September 2026. It also covers Artificial Analysis Music Arena rankings and how to get started.
Suno is the most complete AI music generator for full songs with vocals in 2026, and its free plan gives 50 credits a day, enough for 10 songs (as of September 2026). On September 9, 2026, Suno replaced its older models with v6, developed with Warner Music Group, BMG and Believe. Udio also makes full songs but has disabled downloads, Stable Audio offers open weights for developers, and Mubert focuses on background music.
Suno v6 tops this list for full songs, with 50 free daily credits, stems and generations up to 8 minutes. Udio makes full songs with vocals, but downloads have been disabled since its October 2025 deal with Universal Music. Stable Audio 3.0 offers open-weight models for developers. Mubert specializes in background music for content and apps.
Suno v6 generates songs with vocals up to 8 minutes per generation. Free users get 50 credits daily, and each 10-credit generation produces two songs, so the free plan covers 10 songs a day on the smaller v6-mini model (as of September 2026). Paid plans include stem downloads.

Text-to-Music Generation:
Users type descriptions like "upbeat pop song about summer" to generate complete tracks. The AI creates melody, harmony, rhythm, and vocals from text prompts.
Custom Lyrics Mode:
Writers input original lyrics with structure tags [Verse], [Chorus], [Bridge]. Suno generates music matching the lyrical content and emotional tone.
Audio Upload Processing:
Users upload humming, instruments, or voice recordings. Suno transforms these into full productions with backing tracks, harmonies, and arrangements.
Stem Export System:
Stems are included with each song download on Pro and Premier, and Premier adds an advanced split option. Producers mix and edit individual elements in DAW software.
Start with simple text prompts, use structure tags like [Verse] and [Chorus] in custom lyrics, specify instruments and energy levels, then use Extend or Replace Section to refine the parts you want to change.
Basic Workflow:
Enter song description in the prompt box
Select custom mode for original lyrics
Generate 2 variations per prompt
Extend or edit your favorite version
Export stems for further editing (paid plans)
Advanced Techniques:

Combine genres: "jazz-fusion with electronic elements"
Specify instruments: "acoustic guitar, violin, soft drums"
Set energy levels: "high energy," "mellow," "aggressive"
The Artificial Analysis Music Arena, which ranks models by blind listener votes, is the main public comparison. As of September 2026, Suno V5.5 ranked first for vocals and second for instrumentals behind Mureka V9. Suno v6 had not yet been added, and Udio v1.5 Allegro ranked 17th for vocals.
Vocal Quality Rankings (Artificial Analysis vocals leaderboard ↗, September 2026):
#1 Suno V5.5: 1160 Elo
#2 Mureka V9: 1136 Elo
#3 Mureka V8: 1129 Elo
#17 Udio v1.5 Allegro: 956 Elo
Instrumental Quality (Artificial Analysis instrumental leaderboard ↗, September 2026):
#1 Mureka V9: 1177 Elo
#2 Suno V5.5: 1171 Elo
#3 Mureka V8: 1143 Elo
#6 Google Lyria 3 Pro: 1102 Elo
Stable Audio and Mubert are not listed on either leaderboard. Suno retired V5.5 when v6 launched, so rankings will change once v6 is added.
Paid Suno plans grant commercial use rights to songs made while subscribed. Stable Audio's open models are free for commercial use below $1M in annual revenue under Stability's Community License. Free tiers typically restrict use to personal, non-commercial projects.
Ownership Structure:
Suno Pro/Premier: You own songs made while subscribed and can use them commercially; Suno owns free-plan songs, per Suno's help center ↗
Udio: Downloads are disabled, so tracks cannot currently be used outside the platform
Stable Audio: Stability AI Community License ↗, free for commercial use under $1M annual revenue
Mubert: Commercial usage from the Pro plan upward, but no releases on streaming services
Best Practices:
In the US, music made entirely by AI generally cannot be copyrighted, so add your own lyrics or edits if protection matters
Maintain generation logs and prompts as proof of creation
Avoid copying existing copyrighted melodies or lyrics
