## Core Model Context

- Seed Audio 2.0 is positioned as a multimodal sound-scene model rather than only a text-to-speech system.
- The published specification describes T2A, TA2A, TV2A, and TAV2A inputs, up to six minutes of audio, as many as six audio references, and support for 30 languages.
- Seed Audio 2.0 is described as producing separate dialogue, music, ambience, and sound-effect stems with more precise timestamp control.
- A strong prompt should define characters, setting, emotion, pacing, spoken dialogue, music mood, ambience, specific sound events, and important timing cues.
- These Seed Audio 2.0 capabilities are upcoming on SeedAudio.co; the currently available generator still runs Seed Audio 1.0.
- Commercial use depends on the terms of the access channel used to generate audio. Users should check output rights before publishing.

- Do not claim that Seed Audio 2.0 generation is already available on SeedAudio.co.
- Users can currently generate with the Seed Audio 1.0 preview after signing in when provider configuration and credits are available.
- Clearly distinguish published or announced Seed Audio 2.0 capabilities from the current Seed Audio 1.0 generator.
