The developer platform for world models.
Full-stack infrastructure for real-time video and world models. Serverless GPUs, dedicated clusters, and sub-50ms streaming, anywhere on Earth. Now in public beta. Sign up to start building.
World Model SDK for developers.
Build with the Reactor SDK, and stream real-time world models using our globally distributed GPU network. Pull from our catalog of frontier models or bring your own, and go from zero to production in minutes.
import { Reactor } from "@reactor-team/js-sdk";
const video = document.querySelector("video")!;
const reactor = new Reactor({ modelName: "helios" });
// Show frames the moment they arrive.
reactor.on("trackReceived", (name, track) => {
video.srcObject = new MediaStream([track]);
});
// When the session is ready, set a prompt and start.
reactor.on("statusChanged", async (status) => {
if (status !== "ready") return;
const prompt = "Neon cyberpunk world";
await reactor.sendCommand("set_prompt", { prompt });
await reactor.sendCommand("start", {});
});
await reactor.connect(token);Model Library
All top World Models, one API.
Choose from the top production-ready World Models, deployed globally on the Reactor realtime infrastructure. Build groundbreaking new applications using the latest models, at scale.
LingBot
High-fidelity environments with real-time interactive output.
Helios
Interactive real-time video generation with infinite streaming.

Platform
Custom-built, super fast World Models infrastructure.
Fastest inference anywhere
World models run faster on Reactor than anywhere else, thanks to our in-house kernels for NVIDIA, and other architectures.
Sub-50ms streaming
Our proprietary networking layer delivers frames in under 50ms, against a 400ms+ industry average.
import { Reactor } from "@reactor-team/js-sdk" const reactor = new Reactor({ modelName: "helios" }) // stream frames to a video elementreactor.on("trackReceived", (name, track, stream) => { video.srcObject = stream video.play()}) // react to session state changesreactor.on("statusChanged", status => { // connecting → waiting → ready}) // connect — frames start in <50msawait reactor.connect(token)Every major world model on one API
The Reactor SDK gives you access to every leading real-time world model through a single integration, with new models added constantly.
