最有意思的AI音乐模型，让创作不再差点意思

TL;DR - Chinese AI music company YinChao released its V4.0 model, claiming improved prompt understanding, emotional expression, genre fidelity, and multilingual generation. The release expands AI music creation across consumer, professional, overseas, and API products.

• V4.0 was retrained with a redesigned architecture rather than incrementally updated from V3.5.
• It supports ten major languages and opens instrumental-only generation to general users.
• The model reportedly improves instrument separation, arrangement detail, and adherence to conversational or emotion-heavy prompts.
• YinChao says the model was trained entirely on Biren domestic GPUs; its tools include YinChao App, Studio, Hitto, and an enterprise API.
