SeedRealtime full-duplex AI

Watch it. Hear it.Speak with it — live.

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

Full-duplex intelligence for a world that never freezes.

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.

01
SeedRealtime live session surface with camera and microphone — Seed Realtime AI presence for real-time voice

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.

02
SeedRealtime speech-to-structure flow: audio waves becoming data for Seed Realtime AI generation

Proactive moments

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.

03

Natural timing

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

The scene never stops. Neither does understanding.

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.

CONTINUOUS SCENE

YOU“Tell me when the indicator turns green — and who just asked about it.”

Where SeedRealtime fits

Real sessions. Real jobs to be done.

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.

01

Hands-on device help

Guide someone through a physical setup: “this button,” a cable, a status light. Speech stays natural while the session surface keeps presence on camera.

02

Multi-person rooms

Introductions, standups, dinner-table chatter. Seed Realtime AI is positioned for matching names, voices, and who said what when the conversation overlaps.

03

Museums & travel

Walk-and-talk companions for exhibits, menus, and street scenes—ask what you are looking at without stopping to type a prompt.

04

Language practice

Oral drills and tutoring loops that feel like a call: interrupt, rephrase, keep going—closer to live conversation than turn-based chat.

05

In-car copilots

Eyes-up assistance while driving: short spoken answers, low friction turns, and a session model that expects continuous audio.

06

Service & field work

Technicians and support agents who need to talk through a task while looking at equipment, paperwork, or a customer’s screen.

SeedRealtime and GPT-Live, side by side.

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.

DimensionSeedRealtimeGPT-Live
BuilderByteDance SeedOpenAI
Architecture focusNative audio–video full-duplex LLM; perceive, decide, and speak in one loopFull-duplex voice model; continuous listen/speak decisions many times per second
Primary modalitiesUnified audio + video + text streams (“watch, listen, speak”)Spoken full-duplex first; ChatGPT launch without voice+video / screen share
Interaction modelJoint A/V context for intent, deictic “this”, noise-robust timingBackchannels, barge-in, pause while user thinks; tool invoke while talking
Live vision / screenDesigned for continuous camera understanding with speechNot part of GPT-Live ChatGPT launch; video capabilities described as coming later
Deep reasoning patternEnd-to-end multimodal stream; perception and expression in one model pathConversation tempo on Live; heavier work can delegate (e.g. GPT-5.5 pattern)
