beautifully built on @reactorworld
using frontier AI for its intended purpose: going back to hong kong in deus ex (2000). an infinitely explorable version of hong kong which streams in realtime using h3-omni + a jev harness.

In celebration of our FastH3-Omni launch, I vibecoded a pre-visualization studio. Now today, I'm down in LA showing it to studios. What you're seeing here is generated all in real-time, just from reference images and prompts. ⚡️ Open Source repo is in the comments to get started with this on the Reactor API!

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…

What
Can Jev drive a car despite not being able to see? I gave Jev access to an unreleased world model used to train self-driving cars and a local segmentation model to see if it could drive autonomously. TLDR: Kinda? It's a little Crazy Taxi - but kinda amazing this works at all.

Real Time World Models have moved so fast this year it’s almost been unbelievable… Checkout @buckymoore share more on @reactorworld at the center of this revolution in real-time AI
AI models are upgrading at a new speed. OpenAI’s GPT-6 Astra model, released last week, follows a self-controlled “chain-of-thought” reasoning pattern that can evade certain kinds of monitoring. The next value differentiator for improved models may be less about performance and more about auditability. More on Lightwork this week: → ByteDance is working towards releasing a new real-time world model, pressuring Western frontier labs to keep pace. → Personal agents like Meta’s Muse and Instinct are gaining popularity, raising a conversation over personal autonomy with agents. → Some applications are throttling agent traffic. What does this mean for the companies building them? @clairejyz @Machiz @buckymoore 0:00 Welcome, Bucky Moore! 1:12 OpenAI's Astra 3:50 The New AI Model’s Architecture 4:40 AI Safety and Guardrails 8:01 Trusting AI Agents 11:09 The Future of AI Models 12:06 The AI Agent Land Grab 17:09 AI, Trust, and Personal Data 20:12 Improving AI Agent Capabilities 22:11 Enterprise AI Assistants and Personal Context 24:05 AI Agents and the Future of the Web 25:50 ByteDance and World Models 28:19 World Models and Consumer Content 30:56 Reactor and World Model Infrastructure 34:13 Real-Time Video Models and Scaling

we love open source examples @reactorworld with H3 Reference Turbo Realtime! github.com/willemhelmet/twit…
I made it as easy as possible to build your own Twitch livestream using H3 Reference Turbo Realtime! Consistent Character references, ever-evolving LLM show-runners, and a one-click deploy on Render! Link to get started in the comments
