ByteDance Seed · 5 August 2026

Native audio-visual full-duplex LLM that fuses audio, video and text in one stream and can speak up unprompted; rolled out at scale at launch.

One architecture instead of an ASR plus VLM plus TTS cascade. ByteDance's human evaluation says it halves conversational timing problems versus cascaded systems (interruptions, sluggish replies, false triggers).
