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!

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

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

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
