Reactor makes it easy to build applications with real-time world models. In just a few lines of code, you can connect to a model, receive live video at 30 to 60 FPS, and send commands to control what it generates, enabling entirely new types of applications that were not possible before. Key features:
  • Live and interactive: Models stream media to your app at low latency. Send commands to control what generates in real time and receive messages back while it runs.
  • Simple to integrate: A few lines of code connects your app to a world model. SDKs for JavaScript, React, and Python handle the connection, media, and session lifecycle.
  • No infrastructure: Reactor manages streaming, GPU provisioning, session management, and global distribution. You focus on your application.
Reactor lets developers focus on building their application rather than managing the infrastructure required to run world models at interactive latency.
