Question 1

What is YuE2 and how does it generate full songs?

Accepted Answer

YuE2 is an open-weights foundation music model developed by Multimodal Art Projection (M·A·P) and academic collaborators. It unifies symbolic planning (ABC notation and chord progressions) and neural audio diffusion, generating complete songs with full vocals and accompaniment in 48kHz high-fidelity stereo.

Question 2

How does Symbolic Planning differ from black-box AI music models?

Accepted Answer

Traditional AI music generators act as black boxes where users cannot intervene in chord structures, tempo, or melodies. YuE2 first produces an explicit, transparent ABC 2.1 musical score as an intermediate Chain-of-Thought (CoT) representation, allowing human musicians and AI agents to reharmonize, transpose, and adjust arrangements before audio rendering.

Question 3

How does YuE2 compare to Suno v4 on WildSongBench?

Accepted Answer

On WildSongBench (192 real-world prompts), YuE2 (best-of-8) achieves a SongBench score of 6.9632 and single-pass 6.7316, delivering frontier musical coherence, vocal naturalness, and arrangement completeness exceeding mainstream commercial models like Suno v4.

Question 4

What are SheetSage2 and MERT2 in the YuE2 ecosystem?

Accepted Answer

SheetSage2 is YuE2’s audio-to-score transcription model capable of transcribing raw music into structured ABC sheets. MERT2 (and MERT2-FS) is a self-supervised music representation foundation model that excels across the MARBLE benchmark for music understanding and retrieval.

Question 5

Can I edit the chords and melody with natural language?

Accepted Answer

Yes! The built-in YuE2 Music Agent understands music theory and conversational instructions, such as reharmonizing pop chords into jazz ii-V-I progressions, transposing keys, shifting octaves, or verifying measure alignments.

Question 6

What are the licensing terms for YuE2 weights and output audio?

Accepted Answer

YuE2-3B model weights are released by M·A·P under the CC BY-NC 4.0 license, while inference code is Apache 2.0. Individual creators retain rights to use their generated musical pieces in creative projects. Note that AI-generated audio cannot guarantee complete exemption from third-party copyright or Content ID similarity matches; users are advised to review before major commercial distribution.

Question 7

What is the relationship between yue2music.com and the M·A·P team?

Accepted Answer

YuE2 Music Studio (yue2music.com) is an independent, community-driven cloud creation platform built upon the open-source YuE2 foundation model. We provide a hosted Web UI, symbolic editing tools, and GPU inference runners to help musicians create music without setting up local GPU environments. We are not the official academic institution, and we actively maintain and display full academic citations to the original authors.

Question 8

How are credits deducted? Will failed generations be refunded?

Accepted Answer

New users receive 50 complimentary credits upon registration. Rendering a 48kHz master audio track costs 10 credits, while Agent score modifications cost 2 credits. Score inspection and Web Synth preview are 100% free. If a generation task encounters any network or GPU error, all deducted credits are atomically and automatically refunded to your ledger immediately.

Question 9

How long does it take to generate a complete song?

Accepted Answer

The symbolic planning phase (ABC score, chord progression, and lyrics) generates within 2–5 seconds and can be instantly previewed via the browser synthesizer. Final 48kHz master rendering on RunPod GPU workers typically takes 30 to 60 seconds for a standard arrangement (approx. 1 to 2 minutes of music).
