An upbeat summer pop song about driving the coast with friends, windows down, chasing the sunset. Bright synths, punchy drums and a big sing-along chorus.

Mellow lo-fi hip hop for a rainy late night in the city: soft felt piano, vinyl crackle, brushed drums and a slow, relaxed groove.

A warm acoustic folk song about a small coffee shop on a snowy morning. Fingerpicked guitar, light percussion, gentle male vocals and a hopeful bridge.

Suno V6 API FAQ

What is the difference between simple mode and custom mode?

In simple mode the prompt is a description of the song you want and Suno writes the lyrics and arrangement. Turn on custom_mode to send your own lyrics as the prompt and control title, style tags, negative tags and target duration.

How long can a Suno V6 song be?

In custom mode you can ask for 10 to 360 seconds. Duration is a target rather than a guarantee, and very short targets tend to come out around a minute. Without a duration, songs usually run a few minutes.

How many tracks does one request return?

Each generation normally returns two alternative tracks, each with its own cover image, so you can pick the take you like best.

Can I choose the singer's voice or make an instrumental?

Yes. Set instrumental to true for a track without vocals, or set vocal_gender to m or f. The vocal gender raises the odds of that voice but does not guarantee it.

How is Suno V6 billed on 01router?

Suno V6 is billed per generation, regardless of how long the song is. Requests run asynchronously: create a generation, then poll it until it succeeds. Failed generations are refunded automatically.
