A music bed for your clip: Suno v6 or MiniMax Music, and the switch that keeps it wordless

Most of LUVI's video models generate their own sound, but what they generate is the sound of the scene—footsteps, room tone, a line of dialogue. A score is a separate job, and two families in the catalog do it: Suno Chirp, with three Suno v6 engines (v6, v6 mini and v6 wild), and MiniMax Music, in versions 2.6 and 3.0. On October 20, 2026 an instrumental quoted 264 credits on every Suno v6 engine and 300 on both MiniMax Music versions, and none of the settings we tried changed either price. The difference between them is not really the price.

What do you get for one generation?

On Suno v6, two takes. A single generation returns two audio files of the same request, billed once at 264 credits, which changes how you work with it: you are not choosing whether to run it again, you are choosing between two takes you already have. The variety setting decides how far those two takes stray from the most predictable rendition, from off, the conservative end, to max. A bed that has to stay out of the way is a good reason to start at the conservative end.

On MiniMax Music, one track for 300 credits—but with output controls Suno v6 does not offer. Music 2.6 writes mp3, wav or pcm, Music 3.0 mp3 or wav; the sample rate goes to 44.1 kHz, which is the default, and the MP3 bitrate to 256 kbps. If the bed is going into an edit rather than straight onto a social post, a WAV at 44.1 kHz is the practical reason to pay the extra 36 credits.

How do you keep the bed free of vocals?

You keep a bed free of vocals with the Instrumental only switch, and the three models treat a missing switch differently:

• MiniMax Music 3.0 reads an empty lyrics field as an invitation. Leave the field empty with the switch off and the model writes words from your prompt and sings them. With is_instrumental on, the lyrics are ignored.
• MiniMax Music 2.6 cannot write its own words. With the switch off and no lyrics, LUVI stops the request before it reaches the model and tells you to turn the switch on or write lyrics. Once the switch is on, anything left in the lyrics field is dropped.
• Suno v6 makes vocal or instrumental songs from a description, and its switch is called instrumental.

The shortcut is the prompt itself. LUVI reads some settings out of the prompt, and on both MiniMax Music versions the word "instrumental", or a phrase such as "no vocals", turns is_instrumental on before the run. Suno v6 is not covered: in our quotes, the same prompt left its instrumental switch off. On Suno, set the switch by hand.

How do you write the prompt?

Like a brief for a session player, not like a mood. Name the instruments, the tempo, the room and the register, and leave the rest alone:

A slow, warm upright piano figure over soft brushed drums, late-night jazz club, unhurried, room reverb, instrumental.

Two things earn their place in a bed prompt that would be optional elsewhere. Tempo, because a bed that fights the cut is worse than no bed. And space—"room reverb", "close and dry", "distant, behind glass"—because the bed has to sit under dialogue or effects without competing with them. The last word, "instrumental", is there for MiniMax; on Suno v6 it is only a description.

Where does the bed fit in the workflow?

After the picture, not before. Generate the clip, watch it, then write the music prompt to what you are actually looking at—the cut points you ended up with, not the ones you planned. A bed written to an imagined edit almost never lands on the real one.

Length is the other reason to start from the finished cut. Neither MiniMax Music version has a length setting, and Suno v6's duration target works only in custom mode, where the prompt is read as lyrics rather than as a description. A bed described in words comes back at the length the model chooses, so plan to trim it to the cut and fade it out in the edit.

And keep it under the voice. If your clip already generates its own dialogue and effects, the bed is a third layer competing for the same frequencies; ask for something sparse, and ask for it to sit low.

How we checked

• Models: Suno v6, v6 mini and v6 wild; MiniMax Music 2.6 and MiniMax Music 3.0.
• Settings: the same instrumental bed prompt on each; on Suno v6 also custom mode with a 360-second target and variety at max; on MiniMax Music WAV output, and PCM at 16 kHz on 2.6.
• Date and what was read: October 20, 2026—live credit quotes, the models' parameter contracts in LUVI, and the catalog prices on the model pages.
• Results: 264 credits on all three Suno v6 engines and 300 on both MiniMax Music versions, whatever the settings. On both MiniMax versions the word "instrumental" in the prompt switched is_instrumental on in the quote; on Suno v6 neither "instrumental" nor "no vocals" switched instrumental on. No outputs were generated for this post, so it makes no claim about how any of them sounds.
• Drawbacks: we did not test whether the two Suno takes differ usefully from each other, how either family handles a tempo given in beats per minute, or how long a described bed runs.

In LUVI

Open the model from the audio side of the catalog, write the instruments and the tempo, and turn Instrumental only on: by hand on Suno v6, by hand or with the word "instrumental" in the prompt on MiniMax Music. The result lands in your library as an audio file you can play inline and attach to an edit, and the help center covers which models generate sound with the video if you are deciding whether you need a separate bed at all.

New accounts start with 200 credits, and verifying a phone and a card adds up to 1,500 more. You can create a LUVI account and find a bed that fits your cut.
