# eval-rag (Rag Eval) You can run this example with: ```bash npx promptfoo@latest init --example eval-rag cd eval-rag ``` ## Usage To get started, set your OPENAI_API_KEY environment variable. Next, edit promptfooconfig.yaml. Then run: ```bash npx promptfoo@latest eval ``` Afterwards, you can view the results by running `npx promptfoo@latest view`. The config intentionally includes a couple of unsupported `context-recall` facts so the results show both successful and failing RAG metrics. Other model-graded scores can vary with the grading model.
