LLM observability guide showing an AI request traced through prompt context routing model retrieval tools output quality cost latency and user outcome
llm observabilitySeptember 14, 2026

LLM Observability: How to Monitor, Trace, and Debug AI Applications

LLM observability connects prompts, model calls, retrieval, tools, latency, cost, quality, and user outcomes into one production trace. This guide explains what to record, which metrics matter, how to handle sensitive prompt content, how observability differs from monitoring and evaluation, and how traces become debugging and regression data.

How to Route AI Prompts to the Right Model: LLM Routing Strategies and Examples

LLM routing is the process of deciding which model should handle each request instead of sending every prompt to the same model. This guide explains static, capability-based, complexity, cost, latency, quality, cascade, fallback, policy, multimodal, and tool-aware routing, plus how to evaluate routing decisions with real workloads.

How to Debug AI Prompts: Diagnose Failures and Fix the Right Layer

Prompt debugging is not rewriting a prompt until the output looks better. It is the process of identifying which layer actually failed, making the smallest relevant change, and retesting the same case. This guide covers prompt, context, example, schema, tool, model, multimodal, RAG, and agent failures.

How to Prompt AI Agents With MCP: Tools, Resources, Prompts, and Context

MCP does not replace prompt engineering. It expands the prompt surface across agent instructions, server guidance, tool descriptions, schemas, resources, approvals, and tool results. This guide explains how to design those layers for reliable MCP-powered AI agents.

How to Write Multimodal Prompts for Images, Video, Audio, and Files

Multimodal prompting is not just adding an image or file to a text prompt. This guide explains how to assign roles to each input, reference pages and timestamps precisely, separate evidence from instructions, coordinate information across modalities, handle uncertainty, and evaluate multimodal prompts across current AI systems.
