FUZZ-2.0

General Music Creation from Text Inspiration to Custom Lyrics

FUZZ-2.0 is a music generation model in Riffusion's FUZZ series, suitable for turning song themes, style descriptions, or existing lyrics into listenable music. On this platform, it is used through the Producer music entry point, supporting both prompt-based creation and custom lyrics workflows. It is a general-purpose choice for song drafts, soundtrack exploration, and everyday music solution comparisons; for professional production or custom post-processing, consider Pro or Raw.

Core Capabilities

Discover what FUZZ-2.0 can bring to your work.

Define a Song Direction with Text

Organize prompts around themes, moods, and arrangement intentions—for example, describing a rainy-night atmosphere, a jazz style, and a combination of piano and saxophone—then generate music drafts for listening. It is suited to turning abstract ideas into sound concepts, helping creators compare different directions rather than only receiving lyrics or text suggestions.

Bring Existing Lyrics into Creation

When you already have lyrics, you can use custom mode to submit the lyrics and title, and use labels such as Verse and Chorus to express section intentions. This enables song creation around your own text, making it easier to preview how verses and choruses are presented; labels are used to express structure and do not mean melodies are fixed beat by beat or vocal arrangements are locked in.

Integrate Works into Task Workflows

Music generation is delivered as task results, and audio links can be saved together with lyrics, titles, and status information. Applications can use asynchronous mode to obtain a task ID and then query the completed result, or receive results through callbacks; this is suitable for building creation records and listening lists without requiring users to remain on a waiting page.

Use Cases

Start with specific tasks to find where the model can be effective.

Original Song Demos

Enter lyrics that have already been written, a song title, and style intentions to generate song demos for discussion. Lyricists can use them to review section organization and song direction, while production teams can communicate around the same text. Deliverables include listenable audio and corresponding lyric records; musical review is still required before formal production.

Short Film Scoring Exploration

Organize shot moods, narrative themes, and desired instruments into text, and explore scoring directions using instrumental music settings. This is suitable for comparing different options—such as warm, tense, or upbeat—before editing, then importing audio into editing tools for test matching; visual rhythm alignment and final duration trimming should be completed in post-production.

Theme Music Concept Library

Write a set of different prompts around holidays, events, or content series to generate and save theme music candidates. Applications can associate task IDs, prompts, work titles, and audio links to create a replayable concept library, making it easier to compare creative directions and retain text records of each attempt.

How to Choose This Model

Choose based on task complexity, input materials, and expected results.

Choose the General Version First for Everyday Creation

FUZZ-2.0 is suitable for prompt exploration, custom lyric demos, and standard music candidate generation. Compared with Pro and Raw in the same series, its focus is on the general creative workflow: first verify whether the theme, lyrics, and style are suitable, then decide whether to move into professional production or post-processing. If the project has no specific special delivery requirements, you can start by previewing this version.

Compare Pro and Raw by Delivery Goals

FUZZ-2.0 Pro is designed for professional production needs, while FUZZ-2.0 Raw is for creators who want to handle post-processing themselves; they are different versions and their names should not be used interchangeably. When choosing, it is recommended to compare outputs using the same lyrics and style intent, then decide based on your own workflow. Do not judge audio quality, generation speed, or editing capabilities solely by version numbers.

Getting Started: Create a Song Draft for a Content Project

Prepare the inputs first, then proceed to the appropriate application workflow.

Prepare Inputs

Prepare the content theme, target mood, lyrics or instrumental music requirements, and describe the intended use and desired atmosphere.

Organize the Request and Follow-up Workflow

Submit the creation request with the exact FUZZ-2.0 invocation value; select the prompt, lyric, and title fields for the appropriate entry point, and save the task_id and work ID. Complete the preview first, then select subsequent actions according to this model's documentation, without mixing in editing fields from other tiers.

Practical Task Example: Create a Song Draft for a Content Project

Design the task directly based on the inputs and acceptance priorities below.

Recommended Task

Submit model=FUZZ-2.0 through /producer/audios; use prompt to describe the musical direction, and submit lyric and title separately in custom mode.

Key Checks

Preview whether the overall musical direction matches the content, and check the song status, actual duration, and playable audio; select the draft first, then decide on subsequent processing.

Usage Limits

Before formal use, understand the output quality and capability scope.

  • FUZZ-2.0 generation results cannot be delivered according to preset fixed durations, sample rates, or download formats. The duration in the result records the actual length of the work and is not a guarantee of length before generation; projects with strict broadcast or editing specifications should inspect the audio after downloading and perform any necessary conversion.
  • The Producer entry lists operations such as covers, continuations, clip replacement, vocal and instrumental remakes, but the applicable conditions may vary by model and task. When processing existing songs, retain the song ID and verify the intended operation first; do not assume that all editing tools in the service are necessarily supported by this model.
  • Lyric section labels are used to express structural intent, not precise score control; optional intensity parameters and seeds should be used only when applicable to the current model and task, and do not guarantee a fixed melody or reproducible final result. Submitting the same text should not be expected to produce word-for-word singing or an identical finished work; before publishing, listen to the lyric rendering, section transitions, and overall musical effect.

Frequently Asked Questions

Answers to common questions when using FUZZ-2.0.

Are FUZZ-2.0 and FUZZ-2.0 Pro the same model?

No. FUZZ-2.0 is a general-purpose creative option, Pro is designed for professional production needs, and Raw is intended for customized post-production. Use the exact model name when calling it; do not treat the work duration or effects in Pro examples as fixed FUZZ-2.0 performance.

Can I use my own lyrics to generate a song?

Yes. You can submit text through the custom lyrics workflow, set custom=true, and include a song title and creative prompt. Lyrics can use labels such as Verse and Chorus to organize sections. It is recommended to generate a sample first, listen to how the lyrics and sections are rendered, then adjust the text or stylistic intent.

Can FUZZ-2.0 be used for instrumental music creation?

The creation entry provides an instrumental toggle, which can be used to express the generation intent for lyric-free music, with prompts describing mood, style, and instrumental arrangement. Instrumental tasks still require relevant fields to be submitted as requested; after completion, listen to confirm that the result meets the intended soundtrack use.

Do I get an audio file or task information after calling it?

The API delivers JSON. Completed results include work information such as audio_url, and music can be obtained through the audio link. When using async=true, you first receive task_id and then query the result; you can also set callback_url to receive the result associated with the task after it is completed.

What should I prepare for my first FUZZ-2.0 call?

Use POST /producer/audios, set model to FUZZ-2.0, use action=generate for a new work, and prepare prompt and lyric. The request requires both text fields; when using custom lyrics, also set custom=true, and submit the request using valid authorization credentials.
