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.

Try it now: https://t.co/YojJ5qVDrG

[Bryce Schmidtchen @_bschmidtchen]

Make sure to come meet the team @reactorworld this Friday at CVPR @CVPR

Let's chat World Models, Real Time Video, and more!

real time and multi shot, try it out, it’s crazy!

[reactor @reactorworld]

Introducing LongLive 2.0 by @NVIDIA.

Real-time text-to-video with full multi-shot control. Build your story shot by shot, scene by scene.

Available now on Reactor.

[Bryce Schmidtchen @_bschmidtchen]

@malharhar @AppliedInt Wonderful read! You’re killing it!

[Eliott Mogenet @eliott__mogenet]

The next era of animation won't be generated. It'll be explored.

Yoki (予期) is my first film made with world models + video models. The landscapes of Japan, rebuilt as worlds you move a camera through with @reactorworld.

World models are the most underrated storytelling tech right now, and almost no one's using them for film.

Animation made with @invideoOfficial.

[Alberto @taiuti]

Excited to co-host another World Models CVPR event with @reactorworld, this time on Thursday, with our good friends at @sgl_project, Philo Labs, and @CrusoeAI.

Be there or be square https://t.co/8zHMimvcsT

[Bryce Schmidtchen @_bschmidtchen]

you can build this too with @reactorworld

[hugo @hugothomel]

this is the first fully generative gaming platform

no code, everything is handled by models

- create a game from one sentence
- world model generates frames in real time as you play
- characters that see you, react & talk back
- set your own rules in plain english goals, items, win/lose

you can try it now and create your own adventures!

@tiagosada @reactorworld @lightspeedvp @AmplifyPartners @wndrco @Sky9Capital @FPVventures Thanks man

[Bryce Schmidtchen @_bschmidtchen]

@AlbyHojel let's build worlds @AlbyHojel !

[Amber Yang @theamberyang]

When I first met @taiuti and @_bschmidtchen over a year ago, I knew there was something magnetic about them. Through joining their jam sessions in basically every coffee shop in lower haight, I saw their a-ha moment of realizing where we're headed with world models and how it was important to build the picks and shovels for that.

Today, @buckymoore and I are thrilled to share our partnership with @reactorworld that's building the infra platform for real-time video and world models. @lightspeedvp partnered early at the seed and are now doubling down by leading their Series A. It's been magical to watch developers begin to build imaginative worlds on Reactor, and this is just the beginning. More on our partnership here:

@theamberyang @taiuti Such a pleasure to work with you @theamberyang !

@DereWah VP of Engineering!!!

[Bryce Schmidtchen @_bschmidtchen]

A year ago @taiuti and I started tinkering with real-time video in cafes around San Francisco. We’d worked together on Vision Pro at Apple, deep in the real-time systems that power new types of experiences and software.

World models blew us away, but nobody was building infrastructure to run them interactively at scale, so we decided to become that platform. Today we’re announcing Reactor + $59M to unlock a future where real-time world models are accessible to every developer.

[reactor @reactorworld]

Today, we’re coming out of stealth with $59M in seed and Series A funding, led by Lightspeed, with Amplify Partners, WndrCo, Sky9, FPV, and incredible angels.

For a long time, pixels have been pre-rendered and played back passively. World Models change that entirely: pixels are generated on the fly, in real time, in response to what you're doing. Every time computing has made a shift from passive to interactive, entire industries appeared that didn't exist before. We're standing in front of such moment again.

Reactor is the platform for building in the World Model era: the infrastructure that lets any developer build with World Models at global scale. With only a few lines of code, and you're streaming pixels from a frontier World Model into your product, in real time, at massively.

Over the last 6 months, we’ve assembled an all-star team from Apple, Meta, Google, Luma AI, Netflix, and Replicate. We're already partnering with some of the biggest companies in the world, and hundreds of developers are already building on Reactor today.

[Malhar Patel @malharhar]

I wanted my first public video to be learnings from the past 7.5 years here at @AppliedInt. Hopefully it’s useful to the next set of builders 🐻

[Bryce Schmidtchen @_bschmidtchen]

@malharhar @AppliedInt Let’s go Malhar!

[Bryce Schmidtchen @_bschmidtchen]

proud to see @reactorworld on this year's InfraRed 100!

[Redpoint @Redpoint]

The Redpoint InfraRed 100 is now live.

These are the companies building the infrastructure that powers everything happening in AI right now, from world models and agent runtimes to the sandboxes, databases, and security tools agents depend on.

Congratulations to this year's honorees!

@reactorworld will be your kid's favorite new toy

[Sai Tiger Raina @raina_sai]

Took 2 of my nephew's drawings and made them into worlds he can walk inside.
Now he says, "Make it rain," and the sky cracks open.

1 hour at the airport, with @reactorworld
This is what AI is actually for.
