Reference Architecture for AI Evaluation at Scale

Right now, most enterprise AI teams are obsessing over the exact same wrong question:

Infographic: “Building Trustworthy Agentic AI” by Satish Gopinathan (www.eagleeyethinker.com).

Top section contrasts “Old World: Isolated Model Scores” (Which model is better?) with “New World: Managed System of Decisions” (Can we trust this in production?).

Middle section outlines 3 control planes using a self-driving car metaphor:

Observability (LangSmith): Traces steps (Prompt → Retrieval → Reasoning → Output) to answer “What happened?” for faster debugging.
