ByteDance has officially launched SeedRealtime, a native full-duplex audio-video large model, according to a Cailianshe report carried by PANews on Aug 5. The model does not rely on stitching separate speech, vision and text components into a pipeline. Instead, it uses a unified architecture that natively fuses all three modalities. That design lets SeedRealtime process continuous multimodal information streams in real time, enabling back-and-forth interaction that carries audio, visuals and text together. ByteDance describes the resulting experience as one where the model can look, listen and speak at the same time. End-to-end human evaluations show that conversation pacing problems fell by half compared with cascade models. The improvement shows up in how naturally the model times its responses: instances of being cut off mid-sentence, replying only after a long pause, or being triggered by background noise and casual chatter all decreased markedly. In addition, the likelihood of completing a single dialogue turn smoothly and coherently improved by a clear margin. SeedRealtime has now gone fully live on the Doubao app, making the new multimodal interaction capability available to users at scale.
