Microcosmos GPU simulator enables scalable artificial life evolution
Elastic filaments in 2D fluid world scale linearly with particle count
Deep Dive
Microcosmos is a simulation engine where artificial lifeforms are modeled as elastic filament chains in a 2D viscous fluid world, built from the ground up for modern GPU hardware and end-to-end differentiable. Four experiments validate the engine: hand-designed locomotion, gradient-based filament folding, neuroevolution and quality-diversity search for swimming and chemotaxis, and linear scaling with particle count. Accepted at ALIFE 2026, Microcosmos is released as an open platform for large-scale open-ended evolution.
Key Points
- Lifeforms modeled as elastic filament chains in a 2D viscous fluid world with full physical coupling
- Designed for modern GPU hardware with end-to-end differentiability for gradient-based optimization
- Linear scaling with particle count enables large-scale open-ended evolution, validated on neuroevolution and quality-diversity tasks
Why It Matters
Opens new possibilities for scalable AI and biological simulation on consumer GPUs.
