Vivix-A1: AI Characters That Live in Open Worlds
The first real-time, full-duplex model for interactive AI beings that perceive, move, act, and respond inside open worlds.
Most digital humans today are still talking avatars confined to upper-body movement. They can speak and perform a limited set of gestures, but they cannot truly understand the space around them, move freely through it, or interact with the objects within it.
Vivix-A1 moves beyond the fixed frame. Its characters can listen, understand, speak, move, and act inside open worlds—reacting to what they see and hear, interacting with objects, adapting to changes in the environment, and remaining responsive as each interaction unfolds.
See Vivix-A1 in Action
Watch a person and an AI character build a natural sense of connection through real-time interaction. As they interact, the character responds with emotion, moves freely through the scene, acts naturally with its whole body, interacts with objects, and adapts as the world changes around them—all without breaking the flow of the experience.

Beyond Avatars: Full-Duplex Interaction in Open Worlds—Listening, Responding, and Acting Simultaneously
Traditional avatars remain fixed in place, limited to lip movements and a small set of predefined gestures. Their interactions are also turn-based: you speak, wait, and watch the character finish its response before anything can change.
Vivix-A1 enables continuous, full-duplex interaction with natural full-body movement. It can receive new input while speaking, moving, and acting, allowing you to interrupt, redirect the conversation, or give it a new instruction at any moment.
Ask it to cross a room, turn toward something nearby, pick up an object, or bring it to you. Vivix-A1 can translate your request into natural action within the world while remaining responsive to what happens next.
Listening, responding, and acting are no longer separate steps, but part of one continuous interaction.
Sense: Responds to the Wind
Act: Moves Through the World and Interacts with Objects
Perform: Full-Body Dance
Full-Duplex: Redirects the Story in Real Time
Say It. Type It. Show It. See It Happen.
Vivix-A1 natively supports voice, text, and image inputs, allowing you to guide the character at any moment—even after the interaction has begun. Each input can shape not only what the character says, but also how it looks, moves, behaves, and interacts with the world around it.
Visual references do more than define the first frame. Upload a new image during a live interaction, and Vivix-A1 can respond to it in real time—using the new context to shape the character, the world, and what happens next.
Show Vivix-A1 a new product, for example, and the character can bring it into the scene, turn toward it, pick it up, and begin presenting it to you.
Voice: Talks with You About the Restaurant
Text: Shows You How to Make Tomato Beef Brisket
Conversation, Without the Wait.
Traditional video models generate several seconds of content at a time. In a live interaction, that means waiting for each new clip before the conversation can continue.
Vivix-A1 is built for streaming generation, producing audio and video in small, continuous segments rather than waiting for a full clip to finish. This enables fluid, real-time interaction as the conversation unfolds.
Each new moment builds naturally on what came before. Throughout the interaction, Vivix-A1 preserves continuity and consistency across the character, scene, voice, and motion—while keeping movement expressive and interactions responsive.
With Vivix-A1, you interact with a character who feels present—not a video that keeps you waiting.
