What stands out
What its maker marketed at launch, and what people found later, each with its source.
Native audio-visual full-duplex LLM
Single end-to-end model perceives continuous audio, video and text streams while listening and speaking (no ASR/VLM/TTS cascade); resolves homophones from visual context and temporal references to what it sees.
Proactive turn-taking
ByteDance says it halves audio-visual conversational pacing problems vs cascaded systems (fewer cut-offs, slow replies, false triggers) and can speak up proactively.
Notes
Deployed at scale in the Doubao app (Dola internationally). Some press calls it the first model to watch, listen and speak simultaneously; not claimed by ByteDance, and Gemini Live / GPT-Realtime already accepted video.
