SeedRealtime
SeedRealtime is ByteDance’s native full-duplex audio-visual language model for continuous conversation. It unifies text, audio, video, conversational timing, and response generation in one architecture. Streaming perception allows it to use the user’s environment to resolve ambiguous speech and maintain context in noisy multi-speaker scenes. The model was publicly described as fully rolled out in ByteDance products. Future tool-driven actions remain roadmap work; the launch does not establish downloadable weights or a general developer API.
