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

Discover what FUZZ-2.0 can bring to your work.
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 a music draft you can preview. It is suited to turning abstract ideas into sound concepts, helping creators compare different directions rather than merely receiving a set of lyrics or text suggestions.
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 allows you to create songs around your own text and conveniently preview how verses and choruses are presented; labels express structure and do not mean fixing the melody beat by beat or locking in vocal arrangements.
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 preview lists without requiring users to remain on a waiting page.
Start with specific tasks to find where the model can be effective.
Enter lyrics you have already written, a song title, and style intentions to generate a song demo for discussion. Lyricists can use it to review section organization and song direction, while production teams can communicate around the same text. The deliverables are previewable audio and the corresponding lyric record; musical review is still needed before formal production.
Organize scene emotions, narrative themes, and desired instruments into text, then explore scoring directions with instrumental settings. This is suitable for comparing different options—such as warm, tense, or upbeat—before editing, then importing the audio into editing tools for trial matching; visual rhythm alignment and final duration trimming should be completed in post-production.
Write a set of different prompts around holidays, events, or content series to generate and save theme music candidates. Applications can link task IDs, prompts, work titles, and audio links to create a replayable concept library, making it easy to compare creative directions and preserve the text record of each attempt.
Choose based on task complexity, input materials, and expected results.
FUZZ-2.0 is suitable for prompt exploration, custom lyric demos, and regular music candidate generation. Compared with the Pro and Raw models in the same series, its focus is on a 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, start by listening to this version.
FUZZ-2.0 Pro is designed for professional production needs, while FUZZ-2.0 Raw is designed for creators who want to do their own post-processing; they are different versions and their names should not be used interchangeably. When choosing, compare outputs using the same lyrics and style intent, then decide based on your own processing workflow. Do not judge audio quality, generation speed, or editing capabilities solely by version number.

Answers to common questions about using FUZZ-2.0.
No. FUZZ-2.0 is a general-purpose creative option, Pro is designed for professional production needs, and Raw is intended for customized post-processing. When calling the model, use the exact model name, and do not treat the work duration or effects in Pro examples as fixed FUZZ-2.0 performance.
You can submit text through the custom lyrics workflow, set custom=true, and include a song title and creation prompt. Lyrics can use tags such as Verse and Chorus to organize sections. It is recommended to generate a draft first, listen to how the lyrics and sections are presented, then adjust the text or stylistic intent.
The creation interface provides an instrumental switch, which can express the intent to generate music without lyrics, while prompts can describe the mood, style, and instrument arrangement. Instrumental tasks still require the relevant fields specified by the request, and you should listen after completion to confirm that the result suits the intended soundtrack use.
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 a 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.
Use POST /producer/audios, set model to FUZZ-2.0, use action=generate for new works, and prepare prompt and lyric. The request requires these two text fields; when using custom lyrics, also set custom=true and submit the request with valid authorization credentials.
