Confirmed
The takeaway
ByteDance Seed launched SeedRealtime, an end-to-end LLM that listens, watches (live video) and speaks at the same time instead of chaining ASR, vision and TTS, and rolled it out at scale in Doubao (Dola internationally).

What happened
ByteDance’s Seed team shipped an audio-visual full-duplex model to Doubao, China’s largest consumer chatbot, letting users hold natural video-call-style conversations with the assistant (demos include menu translation, museum guiding and walking through an espresso machine).
Why it matters
It puts end-to-end “see, hear and talk at once” interaction in front of a mass consumer audience. ByteDance published only human-evaluation claims, no quantitative benchmarks.
