## Google's OpenRL for Kubernetes
Google donated OpenRL, a self-hosted reinforcement learning framework for Kubernetes, to streamline AI model fine-tuning without infrastructure complexity.

> If you look at reinforcement learning, i think of it as a kind of a super app of ai because it involves training. it involves sampling. it involves agents actually doing things in a sandbox and sometimes kind of evaluating the work
## OpenRL's Research Preview
OpenRL debuted as a research preview in June 2026, offering a self-hosted training API for a company's own Kubernetes cluster.
## Separating Infrastructure and Research
OpenRL splits the reinforcement learning loop from compute plumbing, allowing infrastructure engineers to handle scaling while researchers control experiments.
## Agent Substrate for Sandboxes
Google's Agent Substrate packs more sandboxes onto limited compute for running millions of isolated commands.
## Sandbox Safety Example
Santa Barbara said kubectl-ai could have formatted his hard disk, so he wanted a sandbox to isolate failures.

> We built kubectl-ai, and in theory, kubectl-ai could have formatted my hard disk
## Key takeaway

Google donated OpenRL, a self-hosted reinforcement learning framework for Kubernetes, to streamline AI model fine-tuning without infrastructure complexity.
