RTNEAT Studio runs a population of neural-network agents on a 2D grid. They wander, they sense, they get scored — and only the best survive. Drag a slider, change the goal, watch them learn. No setup, no code.
Think of it like breeding pets, but the pets are tiny networks of artificial neurons and they're trying to survive in a video game you wrote the rules for.
64 agents are born with random brains — small neural networks with 4 inputs (their senses) and 8 outputs (how they move).
Every tick, each agent earns a fitness score based on the goal you set. The best survive, copies of their brains get small random changes, and weak ones get replaced.
NEAT (NeuroEvolution of Augmenting Topologies) adds new neurons and connections over time. The networks literally get bigger and smarter as they evolve.
Hit play, pause, rewind. Watch one brain or compare them all. Tweak the goal until something cool happens.
No account, no install. Just open the studio and hit play.
