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 v5/v6 and Udio on SongBench?

Accepted Answer

On WildSongBench (192 real-world prompts), YuE2 (best-of-8) achieves a SongBench score of 6.9632, surpassing Suno v5 (6.8721), Suno v6 (6.5562), and Udio. It delivers frontier musical coherence, vocal naturalness, and arrangement completeness.

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 commercial rights and licensing for music generated on YuE2?

Accepted Answer

YuE2 foundation model weights and code are released under open-weights permissive licenses (Apache 2.0). Creators maintain ownership of the original prompts, edited ABC scores, and output audio tracks they generate on yue2music.com.
