Xiaomi has open-sourced 7K of the RL environments it used to train MiMo on Hugging Face, spanning code, cyber, general, music, and web dev domains, all in a uniform Harbor format.
- Workflow: pick a task, a model, a harness, and a sandbox provider, then run; via OpenEnv these can be used directly for training, not just evaluation.
The sharer calls it one of the biggest releases in frontier open-source RL environment data, with an in-depth analysis to follow.
