What you're about to see

A simulated production eval pipeline — the missing layer in most AI deployments

What you're seeing

LLM-as-Judge scoring responses in real time
Offline batch evals vs. live traffic sampling
CI regression gate blocking bad model updates
Human-in-the-Loop checkpoint on high-stakes transitions

Why it matters

Uncontrolled AI drift costs ~$2.3M per major incident (Gartner 2025)
73% of enterprise AI failures are caught by eval gating before prod
HITL checkpoints reduce unreviewed agent errors by 89%
Full trace-ID auditability satisfies SOC 2 Type II requirements

Industry benchmarks — illustrative framing, not personal metrics.

Production-derived patterns

The eval thresholds shown here (fidelity ≥ 0.85, hallucination ≤ 0.10, p95 latency < 500ms) are calibrated from real LLM deployment patterns at Krutrim, where drift monitoring and CI eval gating ran across a 200+ engineer org. The architecture is not a prototype — it reflects how quality regressions were actually caught before reaching users.

LLM-as-Judge

A second LLM scores each response against weighted criteria before it reaches the user.

Prompt

What is Prasad's most significant leadership achievement at Krutrim?

Response under evaluation

Prasad led the development of India's first Agentic AI platform at Krutrim, managing a team of 200+ engineers. He architected the end-to-end LLM infrastructure that powers Krutrim's products and scaled the AI org from 40 to 200 engineers within 18 months.

Offline vs Online Evals

Offline evals run on a curated dataset before deploy. Online evals sample live traffic in production.

Regression Gate (CI)

Eval scores are compared against a stored baseline on every push. A regression blocks the deploy.

How this pipeline fits together

1. LLM-as-Judge — a separate model scores every sampled response against weighted criteria (accuracy, relevance, completeness, conciseness).
2. Offline evals — a curated 27-case golden dataset runs on every CI push; one failing case blocks the merge.
3. Online evals — 1% of live traffic is scored asynchronously; drift triggers an alert before it becomes a customer problem.
4. Regression gate — fidelity and hallucination scores are compared to a stored baseline; a regression of more than 5% blocks the deploy entirely.

This pattern ships inside src/lib/eval-engine.ts and src/lib/guardrails.ts and runs as part of the CI suite on every push.
