Our mission — “vibe-coding interactive worlds” — was never just about code-generation. It’s about using AI to give people programmatic control without needing to code. All these clips are *gameplay videos*; infinitely persistent, created by people with have no domain knowledge.
What if you could build a gameplay with precision, then restyle it to look like anything - anime, fantasy, cyberpunk? Introducing Reverie: a real-time, programmable diffusion model trained for games, capable of conditioning beyond pixels. AI tools are only meaningful when they

There’s been amazing progress in generative video AI models but … with almost no impact on gaming. Games require not just painting beautiful scenes, but having an interactive simulation with state, structure, mechanics … and unbounded runtime. @moonlake is delivering that!

Prompt: “A vibrant international restaurant” Stumbled upon my text to 3D world generation result from a year ago - still one of my favorites :)

Restyling games is much harder than generating a video. Games can’t unintentionally “reset” at every frame: • Your character should stay the same when the camera moves • Damage, lighting, and objects must persist • A room should look the same when you look away and look back

People are massively under-realizing the potential of "AI generation as programmable game mechanics" — especially with how fast we're progressing towards taming model hallucination. In Reverie, I hack together this simple example: 1. Full moon → environmental modifier → player

I'm still amazed by how the best world simulation evolve in the form of games over time: @StupidFunWill 🫡 SimCity (1989) SimEarth (1999) The Sims (2000) The Spore (2008) ARK Survival (2015) GTA series (2026) Extrapolating how the action space and fidelity have grown, we will

AI for science needs fine-grained evals that are careful about knowledge cutoffs. Come see work by @tianyu_hua @ZiyuX @benklieger @sangttruong @liang_weixin @sunfanyun presented right now!
🚨 New benchmark alert! 🚨 Can today’s LLMs implement tomorrow’s research ideas? We put them to the test. Introducing #ResearchCodeBench: 212 tasks from 2024–25 ML papers and code, most released after any model’s training cutoff. 🔗 https://t.co/gh4kC8dtr6 🧵

We will enable UGC games at GTA VI level fidelity before November 2026
Hi everyone, Grand Theft Auto VI will now release on Thursday, November 19, 2026. We are sorry for adding additional time to what we realize has been a long wait, but these extra months will allow us to finish the game with the level of polish you have come to expect and

If you work on real-time models, code generation, RL, or ML infra at Meta and are affected by re-org, apply to work with us We already have something better than Horizon Worlds
Moonlake’s models reason through the representation, tools, and models to use to generate interactive experiences. Let us walk you through a generation:

Trillions will be poured into training action-conditioned world models in the coming decade. The bottleneck is in *action-conditioned* data, and video game is the where this type of data naturally accrue today. GENIE is already trained on the largest video game dataset that

Let’s go @sharonal_lee
Excited to host a panel Oct 28 at @aixventureshq, SF on the future of AI-powered gaming, video, and VR during @TechCrunch Disrupt. Featuring @sharonal_lee, @moonlake_ai; @taylorhughes, @HypernaturalAI; and moderator @russellbrandom, TechCrunch. RSVP: https://t.co/D8ABVMQ4ao

Works like this deserve a lot more attention. In embodied AI, the most common argument against physics-based simulation is that deformables are hard/expensive to simulate. Offset Geometric Contact just made it 300x faster. It computes vertex-specific displacement bounds to

My brother and I spent our childhoods inventing worlds and quests, dreaming of stepping inside them. Today, I’m launching Moonlake AI with $28M to make those worlds real.
We raised $28M seed from Threshold Ventures, AIX Ventures, and NVentures (Nvidia's venture capital arm) —alongside 10+ unicorn founders and top AI researchers— to build reasoning models that generate real-time simulations and games. Models are bottlenecked by practical
