An indie hacker has developed a cost-effective method for evaluating Large Language Models (LLMs) in production, avoiding expensive subscription services. The approach involves creating a "golden dataset" of input-output pairs, writing a simple scoring function that uses another LLM (like GPT-4o-mini) to rate responses, and integrating this into a CI/CD pipeline using GitHub Actions. This setup allows for automated regression detection, ensuring that prompt changes don't negatively impact other aspects of the LLM's performance, all at a minimal cost per evaluation. AI
