ACE Music: AI song generator, pricing, free plan and my test

👁 111 reads

ACE Music is a browser-based AI song generator from ACE Studio. Since 11 November 2026 its ACE Music v1 model leads the Artificial Analysis leaderboard for music with vocals (1160 Elo, Suno v6 1144). In my own test it sang my reference lyrics with 104 of 104 words correct, the best result I have measured. This guide collects everything: what it does, what it costs, what the free plan gives you, how it handles lyrics and how it differs from the open ACE-Step and from Suno.

As of 11 November 2026. Model: ACE Music v1 (plus v1.1 Preview). Access: only the acemusic.ai app, no API. Free: 20 credits a day. Paid from $7.90 a month billed yearly. My test: 28 tracks on the Artist plan.

What ACE Music is

You type a description or your own lyrics, pick a style, and ACE Music returns a finished track with vocals or an instrumental. Every generation gives two variants. Behind it is ACE Studio (the site is run by Timedomain, Inc.), founded in 2018, which started with AI singing synthesis. Its first product, ACE Studio, is software for musicians that sings notes and lyrics you enter. ACE Music is the next step: a whole song from one prompt, like Suno.

The app offers three models:

• ACE Music v1: the main model, the one at the top of the leaderboard. Length is automatic or from 30 seconds to 10 minutes.
• ACE Music v1.1 Preview: according to ACE the “most controllable” model, which plans notes before generating sound. No length slider. It switches on automatically for covers and sheet music.
• ACE-Step v1.5 XL: the open model by ACE Studio and StepFun, free in the app with MP3 downloads even on the Free plan.

Where ACE Music v1 ranks

Artificial Analysis, AA-Music-Vocal v1.1 and AA-Music-Instrumental v1.1, read on 11 November 2026. A closed panel of listeners rates blind pairs.

The first place is real but not crushing: the ACE and Suno v6 intervals overlap and ACE has the fewest ratings (2,119). Artificial Analysis says the model is strongest in reggae and dancehall and in orchestral music.

My test in short

Whisper large-v3 after vocal separation (Demucs), two takes per test, 11 November 2026. I wrote the lyrics myself, in Polish, with deliberately hard consonant clusters.

For comparison, in the same reference test in October Eleven Music v2.5 and Lyria 3 Pro scored 103 of 104 and ACE-Step 1.5 running locally 101. Two AI judges with audio input rated the diction of ACE Music v1 at 4.5 out of 5 and its sound at 4.4.

Orchestral instrumental, length set to 180 s, came out at 179 s (first 60 seconds). Generated with ACE Music v1 (author’s account).

Pricing and plans

acemusic.ai pricing, read on 11 November 2026, before tax.

In my test every generation (two tracks) cost 4 credits regardless of length, model and mode, which matches the pricing: 1,000 credits are 500 songs. On the Free plan the open ACE-Step v1.5 has no generation limit and allows MP3 downloads and commercial use.

Features I tried

• Idea mode: one sentence about an autumn pop song. The model wrote full lyrics with intro, two verses, chorus and bridge, and made two tracks of 3:40 and 4:08 in 101 seconds. The AI-written lyrics had a few awkward lines, so check them before you publish.
• Length: 180 seconds set, 179.0 and 179.1 seconds delivered. With automatic length a short lyric gives a short track, as short as 31 seconds.
• Cover a song: my reggae track remade as 80s synthpop. The lyrics survived (47 and 43 of 48 words), but the track shrank from 70 to 47-49 seconds.
• Sing sheet music: from my MIDI file the model took the melody in both variants, but sang the words poorly or replaced them with “la-la-la”.

ACE Music or ACE-Step

These are two different products from the same company. ACE-Step 1.5 has open weights under the MIT license and runs on your own graphics card for free, commercial use included. In October on an RTX 4090 it scored 101 of 104 in the same test. ACE Music v1 is closed and runs only in ACE’s cloud, but it sounds clearly better: the judges gave it 4.4 for sound against 3.6 for ACE-Step. For sketches on a strong GPU ACE-Step is enough; for a finished song I would pick ACE Music.

ACE Music or Suno

On vocals ACE wins by a hair; on instrumentals it does not compete. In my lyric test ACE scored the best result I have measured. The biggest difference for your wallet: Suno Pro at $8 a month billed yearly includes 20 downloads a month, while ACE Creator at $7.90 has unlimited downloads. For instrumental backing tracks, Suno v6 still leads the ranking.

What is missing

• An API. You cannot plug ACE Music v1 into an automation or your own app.
• Fast rap. With automatic length the model squeezes verses into 31-42 seconds.
• Tongue twisters. Dense consonant clusters on fast notes are where most errors happened.

Launch report and the first test: ACE Music v1 tops the AI music leaderboard.
