Tencent AI Lab has launched SongGeneration, an open source music generation model, which breaks through the challenges of sound quality, musicality and generation speed through innovative technical architecture and training methods. The model supports four core functions: intelligent text control, precise style following, multi-track generation and timbre cloning, significantly lowering the threshold of music creation. The three-stage training strategy and multi-dimensional human preference alignment further enhance the generation effect. Authoritative evaluation shows that the model ranks first among open source models, close to the level of commercial models, and has been open to experience in Hugging Face and GitHub, helping to popularize intelligent music creation.
