AI Evaluation & Reliability

An AI system can look impressive in a demo and still behave unpredictably on real users, unfamiliar data, edge cases, new languages, or production workloads.

Relytic evaluates RAG systems, AI agents, LLM applications, document pipelines, and machine-learning systems to determine what works, what fails, and what should be improved next.

The problem

The problem is rarely ‘the model is bad’

AI systems are pipelines.

  • Poor retrieval
  • Damaged document structure
  • Bad context or prompts
  • Inappropriate model choice
  • Incorrect tool use
  • Stale data
  • Failed integrations
  • Generation errors

Without a proper evaluation process, teams change models or prompts without knowing whether they fixed the real problem. We turn those failures into measurable engineering questions.

What we evaluate

  • RAG and enterprise search

    Measure retrieval quality, reranking, groundedness, answer correctness, citation quality, multilingual behavior, and difficult document types.

  • AI agents

    Evaluate task completion, tool selection, workflow correctness, validation, escalation behavior, recovery, and cost.

  • LLM applications

    Test prompts, model choices, structured outputs, hallucinations, consistency, instruction following, safety behavior, and regressions.

  • Document AI

    Compare OCR, extraction, classification, table reconstruction, and multimodal processing using task-specific benchmarks.

  • Machine-learning and computer-vision systems

    Benchmark models, perform sliced error analysis, investigate false positives and negatives, and measure deployment trade-offs.

  • Production behavior

    Track quality alongside latency, throughput, cost, failures, user corrections, abstentions, and other operational metrics.

System anatomy

We build evaluation around the actual decision

A benchmark is useful only if it helps answer a real engineering or business question.

  • Which retrieval configuration should we deploy?
  • Does the new reranker improve ranking?
  • Can an open-source OCR pipeline replace a paid API?
  • Where does the agent fail when using business tools?
  • Is the new model genuinely better?
  • Which failure cases should block release?
  • What accuracy–latency–cost trade-off is acceptable?

We start from the decision and design the evaluation around it.

Measure what matters

A practical evaluation framework

Representative test data should reflect real documents, users, languages, edge cases, and failure modes rather than only generic benchmarks.

FIG. 04 — EVALUATION AS AN ENGINEERING LOOP
Retrieval
Hit@K / Recall@K / MRR / nDCG / relevant-source coverage
Generated answers
Correctness / completeness / groundedness / faithfulness / citation accuracy
Agents
Task success / tool-call correctness / escalation behavior / invalid-action rate / recovery rate
Document intelligence
CER / WER / field accuracy / table-structure accuracy / processing failures
Computer vision
Precision / recall / F1 / mAP / sliced error analysis
Operations
Latency / throughput / cost / failure rate / memory / user corrections

The metric is chosen because it reflects the failure we care about, not because it is popular.

Evidence

Evidence-driven engineering in practice

01

Enterprise RAG and document intelligence

Evaluation datasets and pipelines compared retrieval approaches, rerankers, multilingual embeddings, and document-processing methods across hundreds of thousands of documents in 7 languages, used by hundreds of employees and handling thousands of queries per day.

Tools and methods

  • Hit@K
  • Recall@K
  • MRR
  • nDCG
  • CER
  • WER

Industrial computer vision

Architecture benchmarking, sliced failure analysis, targeted data augmentation, annotation correction, and reevaluation improved a production vision system.

Typical engagements

  • Pre-production reliability review

    Determine whether an AI feature is ready for real users and identify the failure modes that need to be addressed first.

  • RAG benchmark and improvement

    Build an evaluation dataset, measure retrieval and answer quality, compare configurations, and identify the largest bottlenecks.

  • Model or vendor comparison

    Compare proprietary and open-source models, OCR tools, rerankers, embedding models, or other components on your actual data.

  • Agent evaluation

    Create realistic workflow scenarios and measure whether the agent completes tasks correctly, safely, and consistently.

  • Regression-test suite

    Build repeatable tests so future prompt, model, retrieval, or workflow changes can be evaluated before release.

  • Production evaluation framework

    Define the signals, sampling, human review, monitoring, and feedback process needed to measure quality after deployment.

Honest advice

Automated metrics and human evaluation both matter

Some failures can be measured automatically and repeatedly. Others require expert judgment.

High-stakes or domain-specific outputs may need human-reviewed evaluation sets, disagreement analysis, or expert validation.

We use automation where it provides reliable signal and human review where the business meaning cannot be reduced safely to an automatic score.

How we work

From uncertainty to evidence

  1. 01

    Define success

    Translate vague goals such as good answers or accurate extraction into measurable criteria tied to the workflow.

  2. 02

    Build representative test data

    Create evaluation cases that reflect real documents, users, languages, edge cases, and failure modes.

  3. 03

    Measure the pipeline

    Evaluate individual components where useful and the complete end-to-end system where it matters.

  4. 04

    Analyze failures

    Slice results by meaningful categories and inspect retrieval misses, tool failures, and other error patterns.

  5. 05

    Improve and regression-test

    Use discovered failures to guide changes, then rerun the benchmark to verify improvement without new regressions.
