Understanding how your large language model performs requires more than basic monitoring. This article explains how OpenTelemetry and Traceloop’s OpenLLMetry provide complete visibility into LLM operations by capturing token usage, latency, and cost within unified traces. It outlines how developers can instrument their applications, visualize metrics in real time, and use Traceloop’s OpenTelemetry-native platform to simplify observability and performance optimization.

RAG apps can break in production even when the code hasn’t changed. The culprit is rarely a bug. More often, the cause is data drift, concept drift, flawed chunking, embedding limitations, noisy context, or external dependencies. This article explains the hidden causes of silent degradation in RAG systems and how continuous monitoring and evaluation can help keep outputs accurate, relevant, and trustworthy over time.

While Large Language Models (LLMs) are commonly used to evaluate other LLMs' performance, new research shows they produce highly inconsistent scores when rating the same text multiple times, making them unreliable as evaluation tools. The article suggests using established, deterministic metrics like BLEU and ROUGE instead, or implementing statistical methods that account for this scoring variability, to more accurately compare different LLM models and prompts.
