Joint perception
Audio, visual, and temporal signals share one context. The model identifies interaction targets and intent while the scene is still moving — not after a separate ASR → LLM → TTS cascade.
SeedRealtime full-duplex AI
SeedRealtime is a native audio-visual full-duplex LLM that jointly understands sound, vision, and time. It follows a continuous scene, tracks who is speaking, and responds without freezing the conversation into turn-taking chunks.
How SeedRealtime keeps up
Instead of waiting for neatly packaged prompts, SeedRealtime stays on a continuous multimodal stream — overlapping speech, changing scenes, and the natural rhythm of real conversation.

Audio, visual, and temporal signals share one context. The model identifies interaction targets and intent while the scene is still moving — not after a separate ASR → LLM → TTS cascade.

Hold a goal in mind, watch for change, and speak when it matters: an indicator flips, a device is used wrong, an exhibit needs attention — without waiting for another explicit prompt.

Pause through noise, handle interruptions, and avoid talking over people. End-to-end evaluations report roughly half the rhythm errors of traditional cascade full-duplex stacks.
Designed for real life
Point the camera at a workspace, product, document, or group. Keep talking naturally while SeedRealtime tracks faces, voices, gestures, and environmental change in one session.

Where SeedRealtime fits
SeedRealtime is built for moments where people talk while the world around them keeps moving—hands busy, scenes changing, more than one voice in the room.
Guide someone through a physical setup: “this button,” a cable, a status light. Speech stays natural while the session surface keeps presence on camera.
Introductions, standups, dinner-table chatter. Seed Realtime AI is positioned for matching names, voices, and who said what when the conversation overlaps.
Walk-and-talk companions for exhibits, menus, and street scenes—ask what you are looking at without stopping to type a prompt.
Oral drills and tutoring loops that feel like a call: interrupt, rephrase, keep going—closer to live conversation than turn-based chat.
Eyes-up assistance while driving: short spoken answers, low friction turns, and a session model that expects continuous audio.
Technicians and support agents who need to talk through a task while looking at equipment, paperwork, or a customer’s screen.
Category context
Industry coverage and ByteDance Seed’s launch narrative position SeedRealtime against OpenAI’s GPT-Live: both push full-duplex conversation, with different modality bets. Summary below is based on public product posts—not a lab benchmark.
| Dimension | SeedRealtime | GPT-Live |
|---|---|---|
| Builder | ByteDance Seed | OpenAI |
| Architecture focus | Native audio–video full-duplex LLM; perceive, decide, and speak in one loop | Full-duplex voice model; continuous listen/speak decisions many times per second |
| Primary modalities | Unified audio + video + text streams (“watch, listen, speak”) | Spoken full-duplex first; ChatGPT launch without voice+video / screen share |
| Interaction model | Joint A/V context for intent, deictic “this”, noise-robust timing | Backchannels, barge-in, pause while user thinks; tool invoke while talking |
| Live vision / screen | Designed for continuous camera understanding with speech | Not part of GPT-Live ChatGPT launch; video capabilities described as coming later |
| Deep reasoning pattern | End-to-end multimodal stream; perception and expression in one model path | Conversation tempo on Live; heavier work can delegate (e.g. GPT-5.5 pattern) |
| Multi-speaker scenes | Launch demos emphasize multi-person rooms (names ↔ faces ↔ speech) | Optimized for natural two-way conversation rhythm |
| Public access (at launch coverage) | Rolled out in Doubao (video call entry) per Chinese launch coverage | ChatGPT Voice (Go / Plus / Pro tiers reported at launch) |
