What genres can the AI Music API generate?

The API supports a wide range of genres including electronic, classical, ambient, hip-hop, jazz, rock, cinematic scores, lo-fi, R&B, folk, and more. You specify the genre in your text prompt along with mood, tempo, and instrumentation preferences.

Is the generated music royalty-free?

Yes. All music and sound effects generated through the ModelsLab AI Music API are original compositions that are royalty-free for commercial use. You can use them in videos, games, podcasts, advertisements, and applications without additional licensing fees.

How long can generated tracks be?

Generated tracks can range from 5 seconds to 300 seconds (5 minutes). Duration is controlled via the duration parameter in your API request. Shorter tracks generate faster — a 30-second track typically generates in under 10 seconds.

How much does AI music generation cost?

Music generation is priced per generation, typically $0.02-$0.10 per track depending on duration and quality settings. A free tier is available for testing. Subscription plans include bundled generations at lower per-unit costs.

Can I generate sound effects too?

Yes. The API includes a dedicated text-to-SFX endpoint for generating sound effects from text descriptions. Create foley sounds, ambient audio, UI feedback sounds, environmental effects, and any other audio from natural language prompts.

What audio formats are supported?

The API outputs audio in WAV (uncompressed, highest quality) and MP3 (compressed, smaller file size) formats. Specify your preferred format via the format parameter in your request.

What Is the ModelsLab AI Music API?

Generate Original Music from Text Descriptions

The ModelsLab AI Music API generates original music compositions from natural language descriptions. Describe the genre, mood, tempo, instrumentation, and duration — the API returns a royalty-free audio file within seconds. Generated tracks are original compositions, not samples or loops, and are cleared for commercial use without licensing fees.

The API supports text-to-music generation for full tracks and text-to-SFX for sound effects. Both endpoints accept detailed text prompts and return downloadable audio files in WAV or MP3 format.

Text-to-music: generate full compositions from natural language prompts
Text-to-SFX: create custom sound effects from text descriptions
Multiple genres — electronic, classical, ambient, hip-hop, jazz, cinematic, rock
Configurable parameters: BPM (60-200), duration (5-300 seconds), key, instruments
Royalty-free output — commercial use included, no licensing required
Audio output in WAV (uncompressed) and MP3 (compressed) formats

How Does AI Music Generation Compare to Stock Music Libraries?

Traditional stock music libraries charge per-track licensing fees ($15-$200 per track) and often have usage restrictions. AI music generation produces unlimited original tracks at pay-per-generation pricing — typically $0.02-$0.10 per track depending on duration. Each generated track is unique, eliminating the risk of another creator using the same music in a competing project.

Unlike stock libraries, the ModelsLab Music API can generate variations programmatically — produce 10 different versions of a "upbeat corporate intro" and pick the best one, all through API calls. This makes it particularly efficient for A/B testing audio in advertising and for procedural game audio.
