What is Seed-Audio 1.0?

Seed-Audio 1.0 is an audio scene generation model developed by ByteDance's Seed team, released in June 2026. From a single text prompt it generates finished audio with multi-character dialogue, music, sound effects and ambience mixed in one pass, up to 2 minutes per take.

Can I try Seed-Audio 1.0 for free?

Yes. The Yif playground includes free takes so you can hear real output before paying. Paid credit packs remove the watermark and include a commercial license.

Is Yif the official Seed-Audio website?

No. Yif is an independent playground and guide site with no affiliation to ByteDance. Model inference is provided through independently licensed API providers.

Write it like a director,
not like a TTS user.

Seed-Audio reads a labelled cue sheet: who speaks, how fast, what the room sounds like, when the music enters. You describe the scene once. The model performs, records and mixes it in a single take.

Every guide on this site teaches the same grammar you’ll use in the playground. Nothing to unlearn.

[VOICE]A weary detective, low and dry. A younger officer, quick and nervous.

[PACE]Slow, deliberate. Leave a long pause after every question.

[AMBIENCE]Interrogation room: fluorescent hum, distant traffic, a chair creak. Keep it under the voices.

[MUSIC]Sparse double bass. Enters on the second question, gone before the last line.

[SCRIPT]“Where were you at midnight?”
“I already told you. Twice.”
