They make it sound easy.
I guess they think this all happens by magic or something.
So, I laid it out straight for them.
I said, "Yes, I can do it."

Praxis-1, our first world action model, is now available for anyone to use. It is currently the leading open-weights robotics model on the RoboLab leaderboard and outperforms every other world action model on the benchmark. More than that, it’s versatile and easy to fine-tune for new hardware and tasks. We’ve tested it on 9 different robot embodiments so far, in simulation and on real hardware with multiple partners, and we’ve seen it reach good performance on a new embodiment with under 30 minutes of demonstrations. Weights, code and fine-tuning recipes are on GitHub and Hugging Face. It can run on a single RTX 5090 with NVFP4.
We started our robotics work about a year ago with the thesis that the same video pretraining we do for our creative models can be massively useful for building systems that interact with the physical world, and the benefits of transfer are now becoming clear. When I first talked to people in the field, there was a lot of skepticism about whether video models would be useful in robotics at all, and then about whether you could use them as policies. From first principles, it makes sense that if you can predict the future well in pixels, extracting an action representation should be the easy part. Reality caught up with first principles.
One of my favorite things in our technical report is the idea of self-rollouts. Because the model’s performance is bottlenecked by its visual imagination, you can quickly get an intuition for whether it will perform a new task well by rolling out the policy in the model’s imagination. That can speed up evaluation, and it opens a path to doing reinforcement learning in the model’s imagination.
There’s been a lot of discussion recently about frontier LLMs being the bitter-pilled way to solve robotics. But scaling performance from unsupervised video is an even better example of the Bitter Lesson than scaling from text. Praxis-1 is more than 10x faster and 50x cheaper than GPT-6 Astra on the manipulation tasks we tested. Frontier LLMs will keep improving rapidly on the Pareto frontier of cost and performance, but so will world models. There are also great ways of combining the strengths of the two. And we are much farther from saturating multimodal data than we are text.
Thanks to the mighty Runway Robotics team for making this happen, and to our partners for being so generous with their time helping us test the model across a wide range of hardware and tasks.
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.

I read about an experiment where people are paid to build little Lego action figures called Bionicles. They’re paid for each one they complete, but each one pays a little less than the last. $2 for finishing the first one, $1.89 for the second, and 11 cents less for each one after.
The builders are split into two groups. In one group, each Lego figure is taken apart after it’s finished and the pieces put back in the box. In the other, completed figures are kept intact and lined up on the desk in front of them. The more figures they build, the fuller the desk gets.
The second group keeps building longer, even as they get paid less and less.
People want to get paid, sure, but they also want their work to amount to something. At the most basic level, they want their work not to disappear the second it’s done. And that’s just in an experiment.
In real life, work gets tangled up with who you are and how you spend your life. People want something to show for their work. They want to see their creations in their hands, on screen, on display, out in the real world. They want to go to dinner with friends and family, show them something, and say, I made that.
The Valley likes its binaries. Mercenaries versus missionaries. And all the talk about how much we prefer to work with the latter. The Lego experiment draws out a third motivation that the binary misses. For makers, making the thing and the finished thing itself are part of the reward, along with the simple recognition of having made it.
The headlines make AI research look a lot like free agency. Researchers swapping team jerseys and getting poached by big labs and bigger offers. Some of this is real. But the best people always have options. A lot of companies can pay them well. Not that many can give them something genuinely hard and new to work on that really matters.
There are different kinds of things people want to have made.
Some people want to take a new capability and figure out how to package it, get it into people’s hands, make it a bit more useful. Others want to be on the ground floor of creating an entirely new capability. Every technology wave has people moving the frontier, and others figuring out what to build with what just became possible.
I’ve always been drawn to creating that new thing. There’ll always be another chance to arbitrage what’s already been made. And there’s something hard to really price about getting to create the primitive that other people eventually build on. That motivation to keep finding the next crazy thing has kept me playing the long game.
The beauty of building on the frontier is there’s reward on both ends.
There’s a reward while you’re making the thing, especially when it’s hard enough that you don’t know if you can and important enough that people care that you figure it out. Then there’s the thing you’ve brought to life. Over time, the artifacts add up to a body of work. And the body of work becomes part of the reward.
The long-term version of this is pretty simple. Once people make one thing they’re proud of, they tend to want to make another. And it’s nice when the people you spend all day making stuff with feel like your kind of people, and you admire them. You admire how they think, how they approach their craft, their values and standards, their taste.
An underappreciated part of choosing where you work is choosing who you want to become more like.
The pay should still be good. Great, even. But by then, it’s not the only thing keeping you there. A place where you keep getting to make things you’re proud of, surrounded by people you respect, becomes a place you want to stay.
Mercenaries want money. Missionaries want purpose. Makers want to make. They may want money and purpose too, but they want them by way of what they create. Makers want something they’re proud to have made, with people they’re proud to have made it with. Something they hope stays standing when the work is done.
Something to show for it.
