Fiddler Labs

aid: fiddler-labs
name: Fiddler Labs
description: Fiddler Labs (Fiddler AI) is an enterprise AI Observability and Security platform that provides unified visibility,
  context, and control across AI agents, LLM and GenAI applications, and traditional ML models. The Fiddler platform delivers
  standardized telemetry, evaluation, continuous monitoring, real-time guardrails, and auditable governance from development
  through production. Developers integrate through a REST API (v3), an official Python client (fiddler-client), framework
  SDKs (LangChain, LangGraph, OpenTelemetry, Google ADK, Strands, Evals), and a hosted Model Context Protocol (MCP) server
  that exposes GenAI observability data to AI assistants. Capabilities include model and application onboarding, production
  event ingestion, drift and integrity detection, custom metrics, segments, alerting, explainability, LLM gateway routing,
  and trace/span-level agentic observability.
