Using the Neuron Kernel Interface, @reactorworld and Amazon's Neuron Science team built a kernel-centric path to real-time autoregressive diffusion video generation on Trainium.
They tackled the dynamic shapes, memory access patterns, and cache management that make these workloads hard for generic compilers, and built techniques that generalize across models. amazon.science/blog/a-kernel…

NYC HOMIES!!!! I'm hosting a WORLD MODEL HACKATHON with @reactorworld and @GoogleDeepMind on Thursday, October 8th. Come through and build with the latest-and-greatest realtime AI.
We got early access to @HappyOysterAI's world model at @reactorworld, and it's amazing. Posting some examples in this thread

Diffusion Circle with forest vibes! 🌲
Since the original Diffusion Circle organizer @sedielem cannot make it to CVPR in person this year, we coordinated with him and are happy to host the Diffusion Circle this time.
Stop by if you are interested in flow maps, multimodal diffusion models, variational flow matching, action prediction, and all the other hot denoising stuff.
@sumith1896 and @dustin_podell will coordinate. Meeting point: Upper Lobby F / Exhibit Hall F Entrance; see attached pics.
Happening Saturday, June 6, 3:30pm!
We just doubled the capacity at our CVPR event to make room for more people
Come by, there will be top researchers and engineers from the whole community

I made a video game with world models! After reading this amazing article by @AlbyHojel I was inspired to create my own "World Model Harness" using LingBot-World hosted on @reactorworld. Combining real-time frame generation with a VLM creates an agentic loop where the user is able to interact with the generated environment. Would anyone be interested in a tutorial for something like this?

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.
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.

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:

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 🐻
We (@reactorworld ) are hosting an event at CVPR 2026
If you're into World Models and Realtime Video, you should join: luma.com/qpi7kvmv
See you there 🇺🇸

So excited to finally share this!! I've been heads-down building real-time world models with @reactorworld, and today we're opening it up.

I'm hiring a Research Scientist @reactorworld to lead research on real-time interactive world models — frame-by-frame generation that people, agents, and robots can actually drive.
If you think of latency, memory, and quality as one problem, apply below. DMs open.

How does one make sense of SF?
We are living through the craziest computing revolution of the last 2 decades....and 95% of the value being created is within a 4-mile radius in SF (h/t @eladgil )
It's just hard to understand....why is the concentration so high?
What is it about this place? There are good reasons that people will offer...good universities, great companies, talent networks, venture capital yada yada yada
But all of that is hard to emotionally understand.
I tend to try to answer these questions through my own lived experience.
Two things happened this week that brought it home for me.
On Wed evening, two GOATS of the design world (@soleio and @rsms ) did a design talk at SPC.
I saw some other GOATS at the talk (@aaron_ , @benbarry )
And you realize that these GOATS are just so curious about the world. They just want to build and learn. And give back. And with an air of humility and passion. It's so so cool and inspiring.
And then this week we had someone release a mind-bendingly amazing demo of every pixel being generated.
xitter.cf/zan2434/status/2046982…
People were blown away but @eddiejiao_obj and @zan2434 had been jamming creatively for a bunch of time @spc .
And in that entire time, they were surrounded by a culture and environment and ecosystem that says "that is crazy but my god, if it works, then what could happen"
There is wonder, amazement and curiosity.
And passion.
I wish this city were cleaner and better governed (but Dan Lurie is crushing).
We are so lucky to be surrounded by weirdos who love to build.
This is why we are who we are.
Imagine every pixel on your screen, streamed live directly from a model. No HTML, no layout engine, no code. Just exactly what you want to see.
@eddiejiao_obj, @drewocarr and I built a prototype to see how this could actually work, and set out to make it real. We're calling it Flipbook. (1/5)

Only one chance in this lifetime…
Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him.
I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.
