Is YuE2 actually free, or is there a hidden cost?

The model itself is completely free to download and run. The real cost is hardware — you need a GPU with enough VRAM to run it (ideally 16GB or more) and the time to set up ComfyUI. There's no subscription, no credits, and no usage limit.

YuE2: The Open-Source 'Suno Killer' Everyone's Talking About

⚡ Quick Answer

YuE2 is a free, open-source AI model that writes full songs, and its creators published benchmark numbers showing it can outscore Suno. We tested this ourselves — same 5 style prompts fed into both tools — and the real answer is more nuanced than either the hype or the benchmark chart alone suggests.

If you've seen people online calling YuE2a "Suno killer" this week, you're not imagining it — that's genuinely the phrase getting used across Reddit, Medium, and AI news sites. A free 3-billion-parameter model claiming to beat a company worth over $5 billion sounds like exactly the kind of headline that's either huge news or complete hype.

So instead of just repeating the benchmark chart everyone else is sharing, we generated the same 5 songs on Suno and YuE2 using identical style descriptions, then actually listened to both side by side. This article walks through what the benchmark claim really means, what makes YuE2 different from Suno under the hood, what we heard when we tested it ourselves, and the one catch that changes who should actually care about this.

The Claim That Started This — Suno Killer, or Just a Big Number?

Here's where the "Suno killer" headline actually comes from. YuE2's creators tested it on something called WildSongBench — this is a public scoring system researchers use to compare AI-generated songs against each other, based on 192 different song prompts judged for musicality and quality.

On that leaderboard, YuE2's best result does come out on top. But there's an important detail almost every article covering this story skips over, so here it is in plain numbers:

Model	WildSongBench Score	What This Means
YuE2 (best-of-8)	6.9632	Highest of all models tested — but picks the best of 8 tries
Mureka 9	6.9377	Closest paid competitor to YuE2’s best score
Suno v5	6.8721	Beats YuE2’s single-pass score
YuE2 (single pass)	6.7316	What you actually hear on a normal, one-try generation
Suno v5.5	6.7150	Close to YuE2’s single-pass score
Suno v6	6.5562	Beaten by YuE2 on both scores

Notice the two different YuE2 rows. The 6.9632 score — the one making headlines — comes from a method called best-of-8. This means the model generated 8 different versions of each song and only kept the highest-scoring one. The 6.7316 score is what you actually get from a single, normal generation — and that score sits slightly below Suno v5.

Warning: The headline number everyone is sharing is a best-of-8 result, not a single-try result. If you generate one song on YuE2 the normal way, expect something closer to the 6.7316 line in the table above — still genuinely competitive with Suno, but not the outright winner the headlines suggest.

To be fair to YuE2 here, Suno's own product also lets you generate multiple takes and keep your favorite — so "try a few, keep the best one" isn't a trick unique to YuE2. The real difference is cost: trying again on YuE2 costs you a few extra minutes of your own GPU's time, while trying again on Suno costs you credits from your monthly plan.

What Actually Makes YuE2 Different From Suno (Not Just "Also Free")

Being free is the headline, but it's not actually the most interesting thing about YuE2. The real difference is in how each tool turns your words into a finished song.

Sunogoes straight from your text prompt to a finished audio file. You type a description, wait, and get a song back — you never see or touch anything in between. If the melody in the second verse isn't quite right, your only option is to generate again from scratch and hope for something better.

YuE2 works in two steps instead of one. First, it writes out an actual musical plan — the melody and chords — in a plain-text format called ABC notation (this is just a simple way of writing sheet music using letters and numbers instead of musical staff symbols). Only after that plan exists does YuE2 turn it into a finished audio file.

Tip: Because that middle step is plain text, you can open it, read it, and change a single note or chord before you spend any time rendering the final song. Suno gives you no equivalent to this at all — every attempt is a fresh roll of the dice.

In practice, this means YuE2 is closer to a collaborator you can direct, while Suno is closer to a vending machine — you put a prompt in, and whatever comes out is what you get. Neither approach is automatically "better": if you want speed and don't care about editing, Suno's one-step process is simpler. If you want control over the result, YuE2's two-step process gives you something Suno doesn't offer at any price.

YuE2

Suno captures the moodier, more atmospheric side of this style more naturally. YuE2's guitar work holds up well, but the vocal performance feels less emotionally connected to the dark, romantic tone the prompt asked for.

The overall pattern across all 5 songs: Suno consistently produces cleaner, more confident vocals and a more polished overall mix — this is the area where its paid, purpose-built product still has a clear edge. YuE2 holds its own on instrumentation, especially on slower or simpler styles, and it does this completely free, on hardware you already own.

The Catch Nobody Mentions When They Call It a "Suno Killer"

Here's the part most of the excited headlines about YuE2 leave out entirely: YuE2's weights are released under a license called CC BY-NC 4.0. The important part is the "NC," which stands for non-commercial.

In plain terms, this means you're free to use YuE2 for yourself, for learning, or for personal projects — but not for anything you plan to make money from. That rules out monetized YouTube videos, client work, and uploading tracks to stock music libraries, unless you get separate written permission from the model's creators.

Warning: This isn't legal advice — if commercial use matters for your project, read YuE2's full license text yourself before relying on it.

Compare that against Suno, where a $10/month Pro plan grants you commercial rights from the moment you subscribe — you can put those songs in monetized videos, sell them, or use them for client work right away. That's the trade-off underneath the whole "Suno killer" headline: YuE2 wins on price and control, but Suno still wins on being usable for anything that earns you money.

So... Is YuE2 Actually a Suno Killer?

Based on the benchmark numbers and what we actually heard testing it ourselves: not quite, but it's a lot closer than a free, hobbyist-run project has any right to be.

YuE2 makes sense for you if:you want to experiment with AI music without paying anything, you already have a GPU sitting in your PC, you like the idea of being able to open a song and change a chord before committing to a final render, and you're not planning to monetize what you make.

Suno still makes more sense if:you need to monetize your songs in any way, you want the most polished vocal quality with zero setup, or you'd rather pay $10 a month than spend an afternoon installing and configuring something yourself.

The bigger story here isn't really "YuE2 beats Suno." It's that, for the first time, a free tool you can run on your own computer is close enough to a $5 billion paid product that the comparison is even worth having. A year ago, that sentence wouldn't have been true.

Frequently Asked Questions

It depends which number you look at. YuE2's best score (generating 8 versions and keeping the best one) edges out Suno v5 on one benchmark. But YuE2's single-pass score — the one that matches how most people actually use it — sits slightly below Suno v5. Neither tool is a clean, all-round winner; it depends what you're generating and what you care about.

For personal projects and experimenting, yes — YuE2 is free, runs on your own GPU, and lets you edit the song's melody before rendering, which Suno doesn't offer at all. For anything you plan to monetize, no — YuE2's license doesn't currently allow commercial use, so Suno's paid plan is still the only legal path there.

The model itself is completely free to download and run. The real cost is hardware — you need a GPU with enough VRAM to run it comfortably (ideally 16GB or more) and the time to set it up in ComfyUI. There's no subscription, no credits, and no usage limit.

Not under the current license. YuE2 is released under CC BY-NC 4.0, which stands for non-commercial use only. This rules out monetized YouTube videos, client work, and selling tracks, unless you get separate written permission from the model creators.

No. The score is plain text, so you can experiment by changing a letter or two and listening to what happens, without understanding why it works. Knowing basic music theory helps you make more deliberate changes, but it isn't required to try it.

The easiest way is through ComfyUI, since YuE2 support is built in from version 0.35.x onward — no separate custom nodes needed. Our full install guide covers downloading the right model file, generating your first song, and testing it across genres.
