A new interface for simulating reality

Simulate the
unknown.

Kosmic Worlds is building an interactive world model that can initialize from text, images, or video and roll forward into a coherent, steerable simulation. Not just generated footage. A world you can actually move through.

Models
Simulation-first AI for environments, motion, memory, and controllable rollout.
Experience Preview
Prototype Surface
Prompt Image Video
Current world seed
Prompt scenario
First-person movement through a crowded Tokyo side street at night, with reflected neon, narrow passages, and shifting pedestrian motion.
Conditioning
Prompt
Initialize a world from language, image context, or motion.
Interaction
Steerable
Designed for action-conditioned rollout instead of passive playback.
Scene Type
Urban
Each input can seed a different world prior and trajectory surface.
Goal
Simulate
A model that reasons through environments over time, not single frames.
Capabilities

From sparse input to an explorable world.

Kosmic Worlds is being built around a simple idea: the model should infer a place, preserve it through time, and remain responsive to what happens next.

01
Condition
Start from a prompt, reference image, or short clip.
02
Simulate
Roll forward with stronger structure, consistency, and memory.
03
Interact
Treat generation like a steerable environment, not a finished video.
Core signals

Built around multimodal world priors.

The long-term ambition is a system that can take partial evidence, infer a world, and let the user branch into possible futures.

Applications

Useful anywhere a model needs to reason in space and time.

Robotics
Train and stress-test embodied behavior.
Use generated environments to explore navigation, manipulation, and rare scenarios before deployment.
Simulation
Prototype environments before they exist.
Spin up worlds from sparse input and evaluate how layout, motion, and dynamics might evolve.
Training
Create controllable scenarios for learning systems.
Generate variations in context, difficulty, and behavior without building every environment by hand.
Gaming
Build playable worlds from minimal input.
Turn concepts, frames, and short clips into dynamic spaces that players can move through and interact with.
