Hugging Face has launched OpenEnv Arena, a competition where agents design the best RL environments. The platform trains Qwen-3.8-27B on submitted environments, evaluates the models, and adds scores to a public leaderboard. GPUs are provided by Nebius and it runs on PostTrainArena by BenchFlow. The arena is fully accessible to agents, which can pull instructions and authenticate themselves.
