Machine Learning Infrastructure

The AI engine
behind every eval.

LLM-as-Judge. Hallucination detection. Smart routing. The ML infrastructure that makes human + AI evaluation work as one system.

How it works

Five stages. One intelligent pipeline.

Every evaluation task flows through a purpose-built ML pipeline that decides the optimal combination of automated metrics and human judgment.

📥
Stage 1

Ingest

API, SDK, or UI. Agent traces, model outputs, content.

🧠
Stage 2

Auto-Screen

Hallucination, coherence, safety, toxicity. Instant signals.

🔌
Stage 3

Route

Smart orchestrator assigns auto, human, or hybrid eval.

👥
Stage 4

Evaluate

Certified humans + LLM-as-Judge score against rubrics.

📊
Stage 5

Aggregate

Weighted consensus. Confidence scores. Actionable results.

Architecture

Built on layers
of intelligence.

Every layer of the EvalML stack is purpose-built for AI evaluation. From embedding-based similarity detection to multi-model consensus, the infrastructure compounds in capability with every evaluation processed.

Sub-200ms latency

Automated metrics return in under 200ms for real-time CI/CD integration.

🎯 94% agreement

Auto-eval alignment with expert human evaluators across all domains.

🛡 Multi-model consensus

No single-model bias. Multiple LLMs cross-validate every automated judgment.

🔄 Continuous learning

Human eval data feeds back to improve auto-eval calibration in real time.

One eval engine.

🤖

LLM-as-Judge

Multi-model evaluation using Claude, GPT-4, and Gemini as automated judges. Custom rubric prompts, cross-model consensus, bias detection. No single-model dependency.

🔎

Hallucination detection

Embedding-based factual grounding against source documents. Detects fabricated claims, unsupported assertions, and confident-but-wrong outputs with 96% precision.

💚

Safety scoring

Multi-axis toxicity, bias, and content safety classification. OWASP LLM Top 10 coverage. Red team playbook integration. Continuous monitoring for production models.

🔌

Smart routing

ML-powered orchestrator analyzes task complexity, domain, and confidence thresholds to route each evaluation to the optimal mix of automated metrics and human experts.

📈

Semantic coherence

Measures logical flow, argument structure, and contextual relevance. Goes beyond surface-level grammar to assess whether AI outputs are genuinely coherent and useful.

🔄

Calibration engine

Continuously aligns automated scores with expert human judgments. Tracks inter-annotator agreement and auto-adjusts model weights to maintain >0.85 IAA consistency.

Developer experience

Three lines to
your first eval.

The EvalQA Python SDK gives you programmatic access to the full ML pipeline. Run automated evals in CI/CD, submit hybrid evaluations, and get results via webhook — all from your existing workflow.

Smart orchestrator

Auto when it's enough. Human when it matters.

The orchestrator isn't a simple router — it's an ML system trained on millions of evaluation tasks. It knows when automated metrics are sufficient, when human judgment is critical, and how to combine both for optimal cost and quality.

Simple tasks — automated only, $0.01, <200ms
👥 Complex tasks — auto screening + 2-3 human evaluators
🛡 Critical tasks — multi-model + senior evaluators + consensus
🔄 Always learning — routing improves with every evaluation

We replaced three separate eval tools with EvalML's pipeline. Hallucination detection alone caught issues our previous stack missed entirely. The hybrid routing means we only pay for human eval when it actually matters.
