Hugging Face hands OpenEnv, its framework for agent RL training environments, to the AAIF
Announced Oct 22, OpenEnv packages RL environments as containerized services that expose an agent interface, MCP, and the Gym protocol training libraries use, so one environment can plug into different trainers and harnesses. It's run by a multi-company technical committee (Hugging Face, Meta-PyTorch, Microsoft, NVIDIA and others), and next on the roadmap are environment validation and training recipes (AAIF blog).
