Artificial Intelligence Evaluation Guide: EvalOps Playbook

Summary

The "AI Evaluation Guide: EvalOps Playbook" defines EvalOps as a systematic discipline for scoring language model outputs based on eight core parameters: Truthfulness, Helpfulness, Safety & Compliance, Bias & Fairness, Clarity & Communication, Consistency & Reliability, Efficiency, and Robustness. It details a 0-5 scoring scale and a weighted calculation formula: (Σ weight × score) / (Σ weight × 5) × 100. The guide emphasizes that parameter weights vary by task, illustrating this with 12 evaluation scenarios. It also covers automating evaluation using LLM-as-a-Judge, addressing biases like position, verbosity, and self-preference, and validating judges through calibration with human experts using Cohen's kappa (κ) or Krippendorff's alpha (α) for 85-90% agreement. EvalOps integrates into a continuous development cycle via golden datasets (100-300 examples), CI/CD gates, and offline/online monitoring, with specific considerations for RAG and agent systems, and red-teaming for security.

Key takeaway

For MLOps Engineers or AI Directors deploying LLMs, establishing a robust EvalOps pipeline is critical to move beyond subjective "demo-impressions." Implement a multi-dimensional evaluation rubric with task-specific parameter weights and integrate automated LLM-as-a-Judge systems, calibrated against human experts, into your CI/CD pipeline. This ensures continuous quality, cost efficiency, and security, preventing regressions and proactively addressing model drift in production.

Key insights

EvalOps systematically measures AI output quality, integrating scoring into a continuous development and governance pipeline.

Principles

• Evaluation is multi-dimensional, not a single grade.
• Parameter weights vary by task scenario.
• Safety overrides other parameters.

Method

Implement EvalOps by defining 8 parameters, assigning weighted scores (0-5), calibrating LLM-as-a-Judge with human data (Cohen's kappa > 0.6), and integrating into CI/CD with golden datasets (100-300 examples) for continuous monitoring.

In practice

• Use 8 parameters with task-specific weights.
• Calibrate LLM judges with human experts.
• Build golden datasets from real errors.

Topics

• EvalOps
• LLM Evaluation
• AI Governance
• LLM-as-a-Judge
• Golden Datasets
• CI/CD for AI
• Red-Teaming
