What is MusicGen?
MusicGen is a state-of-the-art AI music generation model developed by Meta AI that creates original music from text descriptions and optional melody inputs. The tool allows users to type a description of the music they want—such as genre, mood, tempo, and instrumentation—and generates a corresponding audio file in WAV format. It produces text-conditional music generation, meaning users can specify everything from
MusicGen pricing
Pricing model: Free
Hugging Face Spaces browser demo is completely free—no account required to try the demo. Users can access it without any payment. For local execution via the GitHub repository, it is also free but requires a GPU environment with 8GB VRAM or more recommended. Commercial use is restricted under the CC BY-NC 4.0 license (non-commercial only); for commercial use, users must check Meta's research license terms. Hugging Face Spaces offers optional hardware upgrades for enhanced performance: CPU upgrades at $0.03/hour, GPU accelerators at several dollars per hour, and persistent storage starting at $5/month for 20 GB.

Frequently asked questions about MusicGen
How do I use MusicGen on Hugging Face Spaces?
Access https://huggingface.co/spaces/facebook/MusicGen in your browser. Select a model (small, medium, or large), enter your text prompt in English describing the music content, set the duration in seconds (15-30 seconds for BGM loops, 3-5 seconds for sound effects), then press Generate. After 10 seconds to several minutes, listen with the player and download the WAV file using the download button.
What model sizes are available and which should I choose?
MusicGen offers four models: small (300M parameters, text-to-music only, fastest), medium (1.5B parameters, text-to-music only, balanced), melody (1.5B parameters, supports text-to-music and text+melody to music), and large (3.3B parameters, text-to-music only, highest quality). Check operation with small first, then switch to large if quality is required.
Can I generate music with a melody I already have?
Yes, through Melody mode. Upload an existing audio file or hum through your microphone to guide the style. The model extracts the broad melody from the uploaded WAV and generates music that continues that melody. This is useful for bringing fragmented ideas closer to a finished form.
How long can the generated music be?
The base model generates 15 seconds of music by default, but users can specify the duration from 5 seconds for sound effects to 30 seconds or more for loop BGM. The model is constrained to maximum 30 seconds of input audio due to sine position embeddings, meaning if you input 20 seconds of audio, MusicGen can generate at most 10 more seconds.
Is MusicGen free to use?
Yes, the Hugging Face Spaces browser demo is completely free and requires no account. Local execution via GitHub is also free but requires a GPU environment. However, commercial use is restricted under CC BY-NC 4.0 (non-commercial license), so commercial users must check Meta's research license terms.
What audio format is the output and how do I download it?
MusicGen outputs WAV audio files. After generation completes, listen to the music with the embedded player. If satisfied, click the download button to save the WAV file. The interface also displays a visual waveform video of the generated audio.
Can I run MusicGen locally instead of using Hugging Face?
Yes, clone the open-source code from GitHub and run it in your local environment. This avoids API limits and server congestion. You need a GPU environment with 8GB VRAM or more recommended. Check the license requirements (CC BY-NC 4.0) before using for commercial purposes.
How does MusicGen compare to other AI music generators?
According to Meta's research paper, MusicGen performs better than evaluated baselines including Google's MusicLM, Riffusion, and Moûsai, as evaluated by human listeners for both audio quality and adherence to text description. This is impressive considering MusicLM was trained on ten times more data tracks. MusicGen also uniquely supports melody conditioning via audio upload, which previous competitive generative software lacked.
