Real-time World Models are the next AI frontier.

Today, we @reactorworld are taking the first step towards this reality: our early preview lets you experience worlds generated in real-time, running on our global low-latency infrastructure.

@npceo_ wowza

[Bryce Schmidtchen @_bschmidtchen]

one of my favorite reads so far from our engineering team

a super deep dive on our FastH3-Onmi work

[reactor @reactorworld]

From 49 steps to real time.

Here’s how FastH3-Omni generates a 14.4 second clip in under 14.4 seconds, with all the architecture, math, and engineering behind it: https://t.co/TWzJxeB4G8

@liu_mingyu Hey @liu_mingyu

check them out running in real-time!

Introducing NVIDIA Cosmos-3-Nano on Reactor. Two new models, available now via the Reactor API.

• Sim-Bimanual predicts what a robot sees as you move its arms and grippers.
• Sim-Transfer turns simulations into photorealistic video.

@reactorworld Cosmos3 FTWWW!

Let's go @NVIDIAAI !

[Bryce Schmidtchen @_bschmidtchen]

have you ever controlled a robot arm being generated in real-time?

the time is now!

@npceo_ stunning

[Bryce Schmidtchen @_bschmidtchen]

beautifully built on @reactorworld

[Harvey Michael Pratt @npceo_]

using frontier AI for its intended purpose: going back to hong kong in deus ex (2000).

an infinitely explorable version of hong kong which streams in realtime using h3-omni + a jev harness.

In celebration of our FastH3-Omni launch, I vibecoded a pre-visualization studio. Now today, I'm down in LA showing it to studios.

What you're seeing here is generated all in real-time, just from reference images and prompts. ⚡️

Open Source repo is in the comments to get started with this on the Reactor API!

[Bryce Schmidtchen @_bschmidtchen]

@reactorworld @Greenfield @TechCrunch wooooooooo

[Bryce Schmidtchen @_bschmidtchen]

@viborc @reactorworld Thank you Vibor!

[Bryce Schmidtchen @_bschmidtchen]

@reactorworld @MiniMax_AI @haoailab @nuvalab let's gooooo!

[Bryce Schmidtchen @_bschmidtchen]

this is a huge launch!

FastH3-Omni is FAST and Open Source is coming 1 week from today as well.

it's time to build with real-time video.

[reactor @reactorworld]

Introducing FastH3-Omni.

The fastest and highest-quality open-source version of realtime H3 by @MiniMax_AI, post-trained by FastVideo @haoailab with @nuvalab.

Exclusive preview on the Reactor API until 10.20.2026.

• First and last frame conditioning
• Audio input + strong dialogue
• Up to 3 reference images
• Frontier-level performance

[Bryce Schmidtchen @_bschmidtchen]

@nebiusai @reactorworld Excited about this!

[Bryce Schmidtchen @_bschmidtchen]

@reactorworld 🔥

[Bryce Schmidtchen @_bschmidtchen]

every pixel will be generated in real time

[reactor @reactorworld]

Join our CTO @_bschmidtchen and @nebius for a live webinar on October 15 at 9AM PT: “What Makes Real-Time AI Video Possible?”

We’ll cover our custom inference stack, what developers are building on Reactor, and how Nebius keeps interactive sessions fast and dependable under load.
