ByteDance Seed Introduces SeedRealtime: a Native Audio-Visual Full-Duplex LLM That Watches, Listens and Speaks in One Model
ByteDance's SeedRealtime fuses audio, video, and text into a single model that responds in real time—a native multimodal architecture, not a wrapper.
Why it matters
A new architectural approach to omni-modal LLMs that processes continuous audio-visual streams natively rather than turn-by-turn. This represents a meaningful capability leap in how models handle real-time multimodal interaction, with implications for voice AI, embodied systems, and the next generation of conversational interfaces.
