LLMOps is the engineering practice for building production-grade large language model systems, covering observability, evaluation, cost control, and agent orchestration by treating LLM systems as versioned, monitored, and iteratively improvable software.

This article introduces core concepts and practices for LLM evaluation and AI observability in AI agent systems, emphasizing that evaluation metrics and real-time monitoring tools are essential for ensuring reliable AI agent operation in production environments.
