Today, we’re making Praxis-1 available to everyone. Our state-of-the-art world action model turns video pretraining into control for real robots, and it ships with open weights under Apache 2.0, ready to run and fine-tune on your own hardware.

Runway Dev is now on Codex. Install the plugin, describe what your app should generate and Codex builds it in, with full access to Runway’s video, image and audio models. Built with @OpenAI. Get started at the link below.

Buckle up for a fast takeoff.

Runway MCP is now in Grok Bot. Bring state-of-the-art generation into your chat and create anything you can imagine, without leaving Grok. Get started at the link below.

Agents can now show their reasoning, not just describe it. Visual Thinking is a new research harness that turns an agent's work into real-time video, so every step is visible and easier to follow, check and trust.

Runway has been on a tear over the past couple months. Viral HORSE Video contest Solaris: the world's first Interface World Model Praxis-1: open-weight World Action Model for robotics Project Continuum: operating system research application built around real-time interfaces A video model. An interface model. A robotics model. An operating system. Are you getting it? These are not separate pretrains. They’re different applications, built around the same General World Model backbone, with different post-training on top. All of them are examples of what you can do when you can simulate any pixel. So I asked co-CEO Anastasis Germanidis to co-write an essay with me explaining how video, interfaces, operating systems, and robotics all fit together, why video was the right starting point for World Models, where the world is heading if Runway’s bets are right, and whether or not, as someone who simulates worlds, he believes we’re living in a simulation. Welcome to the future. Enjoy! (Video, of course, made with Runway)

Fresh updates for dots. First up: you can now create your dot straight from your phone in the ChatGPT app on iOS and Android.

Bring your ideas to life with @claudeai Motion + Runway. Use Claude Motion to animate charts, create customer walkthroughs or create short explainers, then bring your work into Runway to generate videos and images. Learn more at the link below.

Ben Affleck reveals he writes Python, understands convolutional neural networks, worked extensively with GPUs, and used his celebrity status to get private looks at Google and OpenAI’s video models “I’ve always been kind of into computers since I was young. Then, when film started to move from analog film to digital, I became more interested in that aspect of it. The visual-effects workflow for many years has included machine learning, so I can write pretty shitty Python scripts and stuff like that. “With convolutional neural networks, which were the precursors to what the transformer can do, which is much more computation simultaneously, you would do things like look at what’s called a tensor. That’s the numerical translation of a visual image in numbers, like the batch number, the frame number and the red, green and blue values of each pixel in each frame. It’s just that simple. That numeric is called a tensor. “You’d use a convolutional neural network to identify patterns that reveal what’s called edge detection or feature extraction, which is identifying patterns well enough to know, this is where the window ledge is, so we can more easily take the green-screen image out and replace it with something. “That was familiar to me early on because, prior to Artists Equity, I had a small visual-effects company. I’ve worked with GPUs a lot too. The visual-effects guys said, ‘Hey, you should see. There are a couple: Google and this other company, OpenAI, are doing really interesting stuff with transformers in video.’ “I’ve learned that I can actually just call up and go, ‘Hey, it’s Ben Affleck. Can I come see what you’re doing?’ Sometimes people say yes, to my astonishment.”
