# ByteDance launches Seed Realtime: native audio-visual full-duplex model

> ByteDance has released SeedRealtime, a model it describes as full-duplex: it can listen, watch, and respond at the same time, the way people actually converse, rather than politely waiting for you to finish. Released on August 5, it processes continuous streams of audio, video, and text inside a single unified architecture instead of chaining together separate speech recognition, vision, and voice-synthesis modules. That design choice is the point. Cascaded systems, where each stage hands off to the next, introduce lag and awkward pacing that make voice assistants feel stilted; ByteDance claims fusing the modalities roughly halves those conversational timing problems. The company is rolling it into Doubao, its popular consumer chatbot app, which means the improvements will be tested against real users at scale rather than in a demo reel. If it holds up, it is a meaningful step toward AI you can interrupt, talk over, and show things to in real time, and another sign that some of the most interesting multimodal work is coming out of China.
