Generate Music with API API Documentation

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 an audio file in about 15 seconds (the median in October 2026). Generated tracks are original compositions, not samples or loops, and ModelsLab’s terms of service let you use them commercially.

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, MP3 or FLAC.

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
Parameters: prompt, duration (30–480 seconds), output_format, bitrate, and init_audio to follow a melody — write BPM, key and instruments into the prompt
Royalty-free output — commercial use included, no licensing required
Audio output in WAV (default), MP3 or FLAC

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 original tracks for cents: the self-hosted song and music endpoints cost $0.001 per second of audio, so a 30-second track is $0.03, and Lyria 3 and Sonauto cost $0.05 and $0.08 per track. 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.

What Music Generation Capabilities Are Available?

Describe the mood, genre, tempo, and instruments — our music generation API returns an original track in about 15 seconds.

Text-to-Music Generation

Describe the music you want in natural language — specify genre, mood, tempo, instruments, and duration. The API generates original compositions matching your description.

Sound Effects Generation

Create custom sound effects from text descriptions. Generate foley sounds, ambient audio, UI sounds, and environmental effects for games, films, and apps.

Multiple Genres and Styles

Generate music across genres — electronic, classical, hip-hop, ambient, jazz, rock, cinematic scores, and more. Describe BPM, key and instrumentation in the prompt.

Royalty-Free Output

All generated music is original and royalty-free for commercial use. Use tracks in videos, games, podcasts, and apps without licensing concerns.

Create production-quality music, sound effects, and audio content through simple API calls.

Get Started

How to Generate Music with Our API

Create original music in three steps.

STEP 01

Step 1: Describe Your Music

Send a text prompt describing the music you want. Specify genre, mood, instruments, tempo, and duration. For example: "upbeat electronic track, 120 BPM, synthesizers, 30 seconds."

STEP 02

Step 2: Generate and Preview

The API processes your request and generates an original music track. Fetch the audio file URL when it is ready — about 15 seconds at the median — or receive it by webhook.

STEP 03

Step 3: Download and Use

Download the generated audio as WAV, MP3 or FLAC. Use it directly in your application, video, game, or any creative project.

AI Music API — Frequently Asked Questions

Any genre you can describe. On the music endpoint, write the genre, mood, tempo and instruments into the prompt; on the song endpoint, put them in caption. There is no separate BPM or key parameter.

ModelsLab’s terms of service say every generation is yours and can be used for commercial purposes, so tracks from the self-hosted music, song and sound effects endpoints carry no licence fee. Lyria 3, Sonauto and ElevenLabs Music also carry their providers’ own usage terms.

The music endpoint (POST /api/v6/voice/music_gen) takes duration from 30 to 480 seconds, 30 by default, and the song endpoint up to 480 seconds. Lyria 3 returns 30-second clips. The median time from request to finished file was about 15 seconds for both endpoints in September and October 2026, queue time included.

The self-hosted song and music endpoints cost $0.001 per second of audio with a $0.0047 minimum, so a 30-second track is $0.03, plus $0.02 when the API writes the lyrics for you. Lyria 3 costs $0.05 and Sonauto $0.08 per track. Plans start at $21/month (Basic, 3,250 API calls).

Yes. POST /api/v6/voice/sfx runs Stable Audio Open 1.0 for 3- to 15-second effects at $0.001 per second of audio ($0.0047 minimum), in MP3, WAV or FLAC.

The music endpoint returns WAV by default, or MP3 or FLAC with output_format, at a bitrate of 128k, 192k or 320k. The song endpoint returns WAV. Lyria 3, Sonauto and ElevenLabs Music return MP3.
