Global scale from day one
A globally distributed GPU network with the uptime and SLAs that real-time production demands, available from day one.
Real-time infrastructure and APIs for developers building with world models, anywhere on Earth.
Powering real-time world model sessions for
Platform
Real-time APIs for world models.
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.

Models
Worlds, video, audio.
One API call away.
Discover real-time models through the Reactor Model APIs. Try them in the playground, then bring interactive worlds, video, and audio into your app.
Reactor Robotics · Early access
Real-time inference for robotics.
Build robotics applications on a globally distributed GPU cloud, with low-latency inference and APIs.
Platform
Custom-built, blazing 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: "reactor/helios" })
// stream frames to a video element
reactor.on("trackReceived", (name, track, stream) => {
video.srcObject = stream
video.play()
})
// react to session state changes
reactor.on("statusChanged", status => {
// connecting → waiting → ready
})
// connect — frames start in <50ms
await 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.
Enterprise
The production platform for world models.
Case study · Overworld
Overworld runs their state-of-the-art Waypoint 1.5 real-time world model on Reactor, globally and low-latency.
- Sub-50ms end-to-end latency, against a 400ms+ industry average.
- Ship to production with a single command.
- 99.99% uptime on dedicated, globally distributed GPUs.
