Moonlake AI Opens Beta for Its World Modeling Agent After Passing 10,000 Users on its Waitlist

Moonlake AI, a frontier research lab building multimodal reasoning models, today announced the open beta launch of its first world modeling agent that powers their Generative Game Engine. Moonlake’s agent enables creators to build interactive worlds and games up to 100x faster and cheaper than traditional methods by making world changes programmable, consistent, and persistent in real time. Starting today, Moonlake will begin granting beta access to game developers and early adopters from its waitlist of more than 10,000 people, including developers from Microsoft, Nvidia, Sony, Google, EA, and others.

Creators Problem: Games Takes Too Long to Reach Product-Market Fit

Even with major advances in generative AI, game development is still slow and expensive. Teams spend weeks or months creating environments, rebuilding assets, and scripting behaviors, only to learn that the game doesn’t have the “magic” for the players to engage with. Other world models generate visuals, but struggle to keep changes coherent across gameplay. Objects drift, details reset, and worlds don’t reliably “remember” what happened, making it difficult to build experiences that feel authored, reactive, and persistent.

“Building games is fundamentally a product-market fit problem. Developers and creators constantly wonder whether players will enjoy what took them months or years of effort to make.” said Fan-Yun Sun, CEO of Moonlake AI. “Moonlake’s agent changes that dynamic by enabling ideas to come to life in minutes and, in one click, get feedback from real players.”

“The bottleneck in digital creation has always been the linear relationship between world complexity and manual labor,” said Chris Manning, General Partner at AIX Ventures and Professor of Machine Learning at Stanford University. “Moonlake’s programmable world models break this scaling law, achieving a 100x gain in production efficiency by moving the heavy lifting into the model’s inference layer.”

Moonlake’s Solution: Programmable, Persistent Generative Worlds

Moonlake’s world modeling agent is a multimodal reasoning stack that orchestrates a whole suite of models as tools, and can autonomously iterate based on visual feedback and gameplay results. It powers Moonlake’s flagship product: a generative game and world engine built to enable creators to author world changes that stay consistent as gameplay continues. Unlike video-only generation, Moonlake’s generations remain stable instead of snapping back or breaking over time. Moonlake will grant access in cohorts, beginning with creators currently on the waitlist. Subscriptions start at $15/month and increase based on usage.

“Setting up a VR project used to take me hours, Moonlake did it in two minutes. It felt like magic. This is rocket fuel for people like me.It’s going to 10x my workflow. I went from hours of setup to watching it happen in real-time. F***ing flawless,” said an alpha user of Moonlake AI. “Unreal and Unity are not fun to use. With Moonlake, I had fun.”

What Developers Get in the Beta

Beta users will be able to test Moonlake’s generative world-building workflows and start building prototype experiences quickly, including:

• An agent that can prototype games and run experiments fast
• Programmable rules to control how environments respond to user inputs
• Persistent world edits that remain coherent through gameplay

“The missing piece in world modeling is control,” said Sharon Lee, co-founder of Moonlake AI. “We built so creators can define what changes, why it changes, and how long it persists, so the world feels designed, not random.”

Moonlake plans to accept 100 waitlist users per day into the beta to ensure a seamless experience for new and existing users. Request access today at: https://www.moonlakeai.com/.
