Five real-time systems you can perturb, measure, and run controlled experiments against. No account and no fixed demo.
live model organisms
Each simulation runs in the browser and exposes the same sandbox, challenge, and hypothesis-lab structure.
Neural-network organisms evolve vision, movement, predation, and speciation from random brains.
Thousands of local agents produce flocking, fragmentation, and coordinated motion.
Two reacting chemicals organize into Turing spots, stripes, mazes, and coral-like fields.
Simple trading agents generate bubbles, crashes, volatility, and a live order book.
Opinions moving through a network form consensus, polarization, and echo chambers.
petri-bench
A contamination-resistant benchmark for hypothesis isolation, controlled experimentation, inferential statistics, and calibrated claims. The ground truth is generated and verified at task creation, then hidden from the agent.
inspect the benchmarkthe hypothesis lab
State a hypothesis, define a control and treatment, run seeded replicates, and inspect effect sizes and corrected significance tests. The lab turns each playground into an experimental instrument rather than a slider toy.
for agents
Model agents can describe a world and run deterministic experiments without opening a browser.
