About InspireMusic

InspireMusic is a unified framework developed by Tongyi Lab at Alibaba Group for generating high-fidelity, long-form music, songs, and audio from text prompts. It integrates a low-bitrate single-codebook audio tokenizer for efficient representation, an autoregressive LLM (based on Qwen2.5) for token prediction, and a super-resolution flow-matching model to produce 48kHz audio. The framework supports text-to-music generation, music continuation, and offers multiple sampling methods (DTCT, RAS, Top-K). It aims to match or surpass top-tier open/closed-source music generation systems in objective and subjective evaluations.
