Researchers have developed CRAX, a new benchmark for reinforcement learning (RL) agents designed to accelerate safety testing in real-world applications. Built on the MuJoCo XLA physics engine, CRAX offers up to a 100x speedup compared to existing benchmarks, enabling more extensive experimentation. The benchmark includes six environment suites and three agent-specific tasks with varying difficulty levels. Initial evaluations of six popular safe RL methods revealed that no single method consistently outperformed others, highlighting the trade-offs between performance and safety, and suggesting that curriculum learning and safety transfer can enhance results in more challenging scenarios.
