Audio

Seed Audio 1.0 is ByteDance Seed's non-streaming audio generation model. Its input is a prompt rather than a script: describe the voice, tone and sound effects you want, and it generates speech or other audio, up to 120 seconds per request.

It can also follow a Seed speaker ID, and suits audiobooks, voice-overs, games and sound design where one prompt sets the whole scene. Hormouz serves Seed Audio 1.0 on two endpoints: the OpenAI-compatible /v1/audio/speech, which returns the audio in the same response, and /v1/predictions for background jobs. Set response_format to mp3 or pcm.

Billing is per second of generated audio, measured on the file you receive; the current rate is in the price table on this page. Hormouz provides stable access to it from inside Iran, with no foreign credit card or circumvention tooling required.
