What is LLM Observability? - The Ultimate LLM Monitoring Guide

LLM observability is crucial for managing and mitigating risks in large language model (LLM) applications. It provides deep insights into the system's components, enabling engineers to debug issues and operate the application efficiently and safely. The three key terminologies related to LLM observability are: 1) LLM monitoring, which involves tracking various aspects of an LLM application in real-time; 2) LLM observability, which goes beyond monitoring to provide in-depth insights into how and why an LLM behaves the way it does; and 3) LLM tracing, which captures the flow of requests and responses as they move through an LLM pipeline. LLM observability is necessary for several reasons, including the need for experimentation with different LLMs, difficulty in debugging LLM applications, infinite possibilities with LLM responses, drift in performance, and hallucinations. The five core pillars of LLM observability are response monitoring, automated evaluations, advanced filtering, application tracing, and human-in-the-loop feedback. To set up LLM observability using Confident AI, it takes just one API call per response, which runs asynchronously in the background to avoid increasing latency. The platform offers a comprehensive suite of tools for end-to-end LLM monitoring and observability, including unit testing capabilities to enhance model development.
