About Fiddler AI

Fiddler AI provides an observability and security platform that monitors, analyzes, explains, and governs predictive ML models, generative AI, and agentic applications across their lifecycle. The platform offers visibility into agent behaviors, root cause analysis for failures, real-time guardrails for safety, faithfulness, PII detection, and policy enforcement. It supports enterprises in building trust through continuous monitoring, auditable logs, and evidence collection for compliance needs like GDPR and HIPAA. Targeted at Fortune 500 companies, particularly in financial services for use cases like fraud detection, risk assessment, and chatbots, Fiddler distinguishes itself with agentic observability, Fiddler Trust Models for cost-effective evaluations, and native integrations with tools like LangGraph and AWS SageMaker.
