What does Fiddler AI do?
Fiddler AI is a control plane designed specifically for enterprises deploying AI agents and models. It provides comprehensive observability, monitoring, and governance tools that allow businesses to track every action, understand every decision, and control outcomes across their AI systems. The platform offers full visibility into the agentic hierarchy, tracking applications throughout their entire lifecycle from development to production.
The platform stands out by offering more than just passive evaluation—it provides continuous monitoring with full execution context and decision lineage. This means you can pinpoint the root causes of issues and understand why your AI systems behave the way they do. Fiddler includes 'batteries included' Trust Models that power enforceable policy guardrails, reliable evaluation systems, and auditable governance frameworks that go beyond standard telemetry.
This tool primarily benefits enterprise teams responsible for deploying and maintaining AI systems in production environments. It's particularly valuable for AI builders, ML engineers, and governance teams at large organizations that need to ensure their AI agents perform reliably, remain protected from risks, and deliver maximum ROI. Real-world use cases include monitoring customer service chatbots, financial risk assessment models, and any mission-critical AI applications where understanding and controlling behavior is essential.
