Enterprise AI observability, security, and governance control plane for models and agents
What Fiddler AI does
Fiddler AI operates an enterprise "AI Control Plane" that unifies observability, security guardrails, and governance for machine learning models, generative AI applications, and autonomous agents. Founded in 2018 by former Meta engineer Krishna Gade, the platform grew out of early work on model explainability and has since expanded to cover the full agentic lifecycle. Fiddler continuously monitors model performance, data and prediction drift, bias across protected attributes, and generative-AI risks such as hallucination, toxicity, and PII/PHI leakage, while enforcing real-time guardrails that can block harmful actions before they reach users. For governance teams it maintains audit trails, documentation, fairness tracking, and executive dashboards designed to map to regulatory expectations including the EU AI Act, NIST AI RMF, GDPR, HIPAA, and model-risk frameworks like SR 11-7. It targets regulated enterprises in financial services, healthcare, insurance, and government, where risk, compliance, and data-science teams share responsibility for AI. Fiddler differentiates through its deep explainability roots and a single pane spanning predictive ML, LLMs, and agents.
Key capabilities
- Model and agent performance monitoring
- Drift and data-integrity detection
- Real-time LLM guardrails
- Explainability (XAI)
- Bias and fairness tracking
- Audit trails and governance dashboards
- Root-cause analysis
Best for
Regulated enterprises needing a single platform for ML, LLM, and agent observability with strong explainability and governance/audit capabilities.
Limitations
Enterprise-focused with custom pricing and no transparent public tiers; the breadth across ML, LLM, and agents can mean a steeper setup and learning curve for smaller teams.
