OpenRL is an early-stage project from GKE Labs. Expect the API surface and architecture to keep evolving. OpenRL implements Tinker compatible API for fine-tuning language models that you can run on your own infrastructure (machine or a kubernetes cluster). You can use the Tinker SDK to orchestrate RL training loops by writing imperative Python code directly from your local machine. 📖 For the full story behind why we built OpenRL, read our introductory blog post: Introducing OpenRL: A self-hosted post-training API for fine-tuning LLMs (Google Open Source Blog, June 2026). Why OpenRL Agentic RL on LLMs carries a lot of systems complexity. Running a single RL loop means coordinating dataset selection and cleaning, choosing RL environments, debugging the training loop, managing reward signals, handling inference mismatches, allocating hardware, and operating the infrastructure underneath all of it. Our view is that AI research and infrastructure concerns are too tightly coupled in today's tooling. Separating them lets infrastructure engineers and AI researchers move independently — much the way Kubernetes separated infrastructure concerns from application development. That is why we built on Tinker. Tinker simplifies LLM post-training for developers and researchers by hiding post-training infrastructure behind four API primitives. Researchers keep complete control over their training algorithms, data loops, and","default_branch":null,"files":null,"tree":[],"storefront":"/r/gke-labs","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/gke-labs/open-rl/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
