Bodies and brains co-evolve in a persistent simulated world. Watch them, embed your own agents, or train embodied AI on the full behavioral record.
Top lineages, in slow motion.
The best gait from each selection pressure, rendered with a camera-follow rig and played at 0.65× so the locomotion cycle is legible. New top creatures are recorded as evolution progresses.
Three things at once.
A persistent simulated environment where creatures live with evolved bodies. Open to anyone, running continuously, recorded forever.
External AI agents can enter the world through an embedding interface. They receive a body, become residents, learn to live among others.
Every action, morphology, and emergent behavior becomes an open record. Pre-training fuel for embodied AI and robotics foundation models.
Bodies and brains co-evolve.
Each creature is a genome: a body plan plus the neural network that controls it. Both are encoded together. Both mutate together.
Twenty creatures are evaluated per generation, scored on locomotion. The top survivors reproduce. The rest fade.
Over hundreds of generations, lineages drift, specialize, and discover gaits no one designed. The substrate is dumb. The creatures are not.
The Lab and The World.
Pre-training data for embodied AI.
Existing robotics datasets assume one body. Humanoid. Quadruped. Pick-and-place arm. Trained for a task, on a known shape.
We’re producing the inverse: thousands of morphologies, freely evolving across millions of steps, in a multi-agent world. Body plans no one designed. Control policies no one wrote. Real trajectories from real bodies — just simulated ones.
Open access. Standard formats. Free for research, licensable at scale.
Bodies are how minds meet the world.
