SeedRealtime is ByteDance's native audio-video full-duplex AI model for realtime interaction, letting people hold face-to-face video conversations with an assistant that watches, listens, and replies on one continuous stream. Released on August 5, 2026, it is built for travelers, shoppers, and students who want help that reacts in the moment instead of waiting for its turn.

Core Features
- Unified architecture that blends audio, video, and text in a single end-to-end network rather than a cascade of separate engines.
- Full-duplex timing: the model senses when to speak, pause, or stay silent, cutting turn-taking glitches by about 50 percent versus cascaded systems.
- Joint audio-visual understanding that resolves words like 'this' by reading the on-screen object, gesture, and conversation history together.
- Noise resistance that ignores background chatter and nearby speakers, so calls in airports or cafes stay on track.
- Active assistance that flags a target in view or corrects a task, such as operating a coffee machine, as the scene changes.
Best For
- Travelers who need live translation of menus and spoken service in a foreign language.
- Museum or retail guides that point out exhibits and products as the camera moves.
- Students reading papers who want page-aware prompts during a study session.
Pricing
SeedRealtime ships inside the Doubao app on Android and iOS at no extra cost; ByteDance has not published a standalone API price. Enterprise use through Volcengine's Seed model family follows custom quotes.
Our Take
Best for natural, interruptible video chat where timing matters; the trade-off is that it currently lives inside Doubao rather than as a portable SDK. For latency-sensitive voice work it is one of the smoothest demos we have seen in 2026.
