Configure custom ServingRuntime CRs on OpenShift AI for model serving frameworks not covered by built-in runtimes. Use when: - "Create a custom serving runtime" - "I need a runtime for ONNX / Triton / custom framework" - "Customize vLLM runtime parameters" - "What serving runtimes are available?" - "Add a custom container image for model serving" Handles listing existing runtimes, creating new ServingRuntime CRs, and validating compatibility with target models. NOT for deploying models (use /model-deploy after runtime is configured). NOT for NIM platform setup (use /nim-setup).
