AI Observability & MLOps

Production AI monitoring, drift detection, evaluation pipelines and continuous model governance.

Observability LayerGovernance Layer
All Blueprints

AI systems degrade silently. Data drift, concept drift, infrastructure degradation and model staleness can cause failures that are invisible without proper observability. This blueprint covers the full production AI observability stack — monitoring, evaluation, alerting, and continuous governance.

When to Use This Blueprint

  • Production AI systems with SLAs and business-critical decisions
  • Regulated models requiring ongoing performance documentation
  • Systems where data distribution shifts are expected over time
  • Multi-model environments requiring unified monitoring
  • Teams needing to demonstrate ongoing model performance to regulators

Architecture Components

Model Performance Monitoring

Accuracy, precision, recall, AUC tracking over time. Business metric correlation. Cohort-level performance disaggregation.

Data Drift Detection

Population Stability Index, KS test, Jensen-Shannon divergence. Feature distribution shift alerting. Reference dataset management.

Concept Drift Detection

Label drift, prediction distribution shifts, feedback loop detection. Windowed evaluation with statistical significance testing.

LLM Evaluation Pipeline

RAGAS for RAG systems, G-Eval, LLM-as-judge patterns. Automated evaluation datasets, regression testing on model updates.

SLO & Alerting Framework

Latency SLOs (p50/p95/p99), accuracy SLOs, data freshness SLOs. PagerDuty/OpsGenie integration, escalation policies.

Experiment Tracking

MLflow, Weights & Biases, Comet. Hyperparameter logging, artifact management, run comparison, team collaboration.

CI/CD for ML

Automated model testing before deployment. Shadow deployment, canary rollout, A/B testing framework, automated rollback.

Decision Framework

Decision: Monitoring Tooling

AEvidently AI (open-source, data drift)
BWhyLabs (managed, enterprise)
CArize AI (LLM + tabular)
DCustom build (maximum control)

Decision: Retraining Strategy

AScheduled (predictable, simple)
BTrigger-based (drift-detected, efficient)
CContinuous (streaming, complex)
DOn-demand (low-frequency models)
