Fiddler is an AI observability and security platform designed to help teams monitor, explain, and govern machine learning models, LLM applications, and agentic AI systems. It provides visibility into model behavior across development and production so users can track performance, identify drift, and investigate issues with root cause analysis.
The platform includes tools for model monitoring, explainable AI, alerting, dashboards, and trust and safety analysis. It supports performance tracking, data integrity checks, fairness and bias analysis, prompt and response inspection, and evaluation of trust-related metrics such as quality, groundedness, privacy, and harmful content. Fiddler also offers observability for multi-agent workflows, with hierarchical tracing that helps teams understand decisions, dependencies, and execution flow across complex AI systems.
Fiddler is built for organizations that need centralized AI model monitoring, LLM observability, and explainability tools to support reliable deployment and ongoing oversight of production AI applications.
