CoinRun: Quantifying generalization in reinforcement learning

AI Impact Summary

CoinRun introduces a standardized RL training environment that quantifies how well agents transfer learned behavior to novel situations. This provides a concrete generalization metric that helps compare state-of-the-art algorithms under controlled variation, without the noise of more complex platformers. For product and research teams, CoinRun serves as a focused benchmark to surface generalization gaps and prioritize robustness-focused improvements.
