TL;DR. The ability to monitor, understand, and troubleshoot the internal workings and predictions of an AI model in production.

Technical Definition

The ability to monitor, understand, and troubleshoot the internal workings and predictions of an AI model in production.

How it works

Model observability is crucial for ensuring the reliability and maintainability of AI systems, especially LLMs. It involves tracking inputs, outputs, internal states, and performance metrics to detect issues like data drift, model degradation, or unexpected behavior. Robust observability tools provide insights that are essential for continuous improvement and responsible operations.
