Building the developer platform for real-time world models.

[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.

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.

Today Reactor is coming out of stealth. We’ve raised $59M in Seed and Series A funding, led by @lightspeedvp, with participation from @AmplifyPartners, @wndrco, @Sky9Capital, and @FPVventures.

Reactor is the platform for building in the World Model era: the infrastructure that lets developers build with them at global scale for the first time. Stream from a frontier World Model to your app, in real time, all in under 10 lines of code.

World Models represent the next major shift in AI: pixels, audio and actions are generated on the fly, in real-time, in response to user inputs, and to the environment. 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.

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

The World Model era starts now.

See you there 🇺🇸

Our demo just got better. We've added new examples and made the whole experience faster.

To celebrate, we're giving away a free PS5 to whoever generates the most impressive world and posts about it by Friday May 22nd at 9AM PST.

Hundreds of thousands of people experienced real-time world generation last week running on our infrastructure.

This was just a glimpse of what's coming.

Welcome to the era of real-time AI

[reactor @reactorworld]

Real-time World Models are the next AI frontier.

Today, we're 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.

Developers who got early access to Reactor have been building experiences that were not possible 6 months ago.

We're hiring the people who want to build what comes next: https://t.co/AKb8dPGB8k

We are moving towards a future where everyone can create anything. What happens when video becomes as programmable as software?

[reactor @reactorworld]

In 2018, Bandersnatch gave you a choice. Netflix had to shoot every ending to make it possible.

What if they didn't have to?

[reactor @reactorworld]

Real-time world models are here. We're handpicking who builds with them first.

Tell us what you'd make: https://t.co/uFuHtnOogw

[reactor @reactorworld]

The jump from passive to interactive has always unlocked possibilities nobody saw coming.

It happened with computers, with the internet, with mobile.

It's happening again with video.

Come build what's next: https://t.co/tlqRPBiSHa

[reactor @reactorworld]

For a century, video has been something you watch.

World models make it something you inhabit.

We're building for that shift.
