OpenEnv Becomes Community-Owned Protocol Layer for Agent Training Across Frameworks

OpenEnv, now co-owned by HuggingFace, Meta-PyTorch, Unsloth, Modal, Prime Intellect, NVIDIA, and others, is a protocol layer that standardizes the interface between models, training harnesses, and environments without dictating reward logic. The motivation is that frontier labs couple model and harness during training — a coupling open-source workflows lack — and OpenEnv provides that socket without locking in any specific trainer or reward framework.
