Choose the evidence your AI decision requires
Assure & Operate


AI Agent Evaluation& Reliability
Take this route when the agent build is release-bound and the same task must run repeatedly, exposing tool behavior, recovery, escalation, and run-to-run variance.


RAG Evaluation &Groundedness Testing
Score retrieval, groundedness, citation, access, and abstention separately here, so each RAG failure lands on the layer whose team can fix it.


AI EvaluationStrategy
Start with evaluation strategy when teams collect scores but have not agreed acceptable behavior, representative cases, critical failures, thresholds, or release authority.


Golden DatasetDevelopment
Build a golden dataset when evaluation cases need traceable sources, calibrated labels, protected splits, ambiguity decisions, coverage checks, and a refresh owner.


Independent AIAgent Evaluation
Independent agent evaluation fits when the build team cannot control test scope, execution, or conclusions for a high-stakes release decision.


Safety &Policy Evaluation
Written safety rules become testable here, paired as a misuse attempt and a legitimate lookalike, then judged for severity, false refusals, and residual risk.


AI LaunchReadiness Review
Run launch readiness when quality, security, privacy, support, and operations evidence is scattered and the release authority needs one dated dossier for a go, conditional-go, or no-go decision.


Prompt Evaluation& QA
Prompt evaluation fits version changes that need fixed cases, recorded settings, shared rubrics, reviewer calibration, failure slices, and a regression gate.


LLM Evaluation& Benchmarking
Benchmark LLMs when public scores cannot answer which model fits your workload, language mix, safety constraints, latency budget, and cost conditions.


Bias, Fairness &Explainability Testing
Reach for this when an aggregate result may hide which group absorbs the errors, and your owner has defined affected groups and acceptable trade-offs.
Why it matters
Averages can hide the failure that matters
A useful evaluation keeps critical cases and user slices in view. It also documents uncertainty and disagreement, with enough context for another reviewer to reproduce the result.
How we work
Settle the decision before choosing the metric
We start with the person who will use the evidence, the failures they cannot accept, and the coverage their decision requires. Only then do we choose metrics, rubrics, and graders.
Scope and ownership
The decision comes first; the metric is chosen to serve it
We start from the person who will use the evidence and the failures they cannot accept.
We name the intended use, the important users, the unacceptable failures, the constraints, and the person who will act on the evidence, then inspect the current system, data, workflow, known failures, and available controls, keeping unknowns visible rather than counting them as passes. Representative cases and suitable checks are chosen only after that, and the critical slices and adverse behaviour that matter to the decision are tested alongside the average. Uncertainty and reviewer disagreement are documented with enough context for someone else to reproduce the result, and the record closes with open exceptions, residual risk, responsible owners, and the condition that would call for another look.
How evaluation evidence reaches a decision
Define the decision
Name the intended use, important users, unacceptable failures, constraints, and the person who will act on the evidence.
Review the starting point
Inspect the current system, data, workflow, known failures, and available controls. Unknowns stay visible rather than counting as passes.
Build and run the evaluation
Choose representative cases and suitable checks, then test the critical slices and adverse behavior that matter to the decision.
Record the result and owners
Document the evidence, open exceptions, residual risk, responsible owners, and what condition would call for another look.
Inside our own team
Five Zeo consultants on what AI is changing in their work
Every operational consultant at Zeo has secure LLM access and training, and AI sits inside the daily work. Five of them came through our AI Bootcamp and wrote down what they expect it to change.
Selected AI sessions
Talks from Digitalzone
Three speakers look at the pace of AI change and what it means for e-commerce and content teams.
People who ship the AI systems they advise on
Agents, chatbots, and RAG systems at Zeo are built by senior engineers who keep operating them after launch. The consultants below are those builders, matched to the work this page covers.
Tools we use
The AI engineering stack behind the work
Models, retrieval, evaluation and observability are separate layers of a working system. These are the ones we build and operate on.
Models and cloud platforms
- Google GeminiLLM Evaluation & Benchmarking's comparisons include Gemini as a candidate model family, giving the benchmark suite a genuine multi-vendor spread rather than testing only the two providers this family defaults to elsewhere.
Agent and automation frameworks
- LlamaIndexRAG Evaluation & Groundedness Testing needs to check what a system actually retrieved before generating, and LlamaIndex is the retrieval layer under test in that specific child's evaluation runs.
- PromptfooSafety & Policy Evaluation's paired-test method, a misuse attempt and its legitimate lookalike judged for refusal quality on both sides, is exactly what Promptfoo's red-team test generation builds.
Application and prompt tooling
- PromptLayerPrompt Evaluation & QA, tracks each prompt revision's scored outcome in PromptLayer, which is what lets a team compare a new prompt version against its predecessor on the same evaluation set rather than trusting a subjective read.
- AgentaFor the specific repeated QA loop Prompt Evaluation & QA describes, testing several prompt variants against the same cases, Agenta's comparison workspace is what this page's account uses to keep human review and automated scoring in one place.
Retrieval, embeddings and memory
- ChromaRAG Evaluation & Groundedness Testing's evaluation runs query Chroma directly to check what a passage under test actually retrieved, kept lightweight enough to run inside the evaluation session itself.
Gateways and hosted inference
- OpenRouterLLM Evaluation & Benchmarking needs to run an identical evaluation set against many candidate models without a separate integration per vendor, and OpenRouter's unified routing is what makes that comparison practical at the scale this page's benchmarking work runs at.
- GroqWhen LLM Evaluation & Benchmarking includes latency as a comparison dimension, Groq's inference speed gives that specific benchmark a real high-end reference point rather than an estimate.
Evaluation and observability
- Weights & BiasesThis page's own hero says a claim needs proof before it's made, and Weights & Biases is where the evaluation history behind that proof lives across LLM Evaluation & Benchmarking and AI Evaluation Strategy, run over run rather than a single snapshot.
- DatadogAI Launch Readiness Review's sign-off depends on what the system actually did under real conditions, not what a design document claims, and Datadog's production monitoring is where that operating evidence is pulled from before a launch decision.
- LangfuseThe hero says representative and critical cases both get tested, and Langfuse's per-run trace is what AI Agent Evaluation & Reliability and Independent AI Agent Evaluation use to reproduce a specific failure rather than re-describe it after the fact.
- Arize PhoenixThe hero's warning that averages can hide the failure that matters is precisely what Arize Phoenix's slice analysis is built to counter, used in AI Agent Evaluation & Reliability and Bias, Fairness & Explainability Testing to find the specific condition where a system's behavior diverges from its average.
- BraintrustIndependent AI Agent Evaluation and LLM Evaluation & Benchmarking both run their scored comparisons in Braintrust, since the page's claim-needs-proof standard means a suite has to be pinned to one named build, not a general impression of capability.
- HeliconeLLM Evaluation & Benchmarking needs a model comparison that accounts for operating cost, not just output quality, and Helicone's per-call cost tracking is what fills in that second half of the comparison.
- TraceloopAI Launch Readiness Review has to confirm a system behaves in production the way its design claimed, and Traceloop's execution traces carry that evidence into the sign-off review.
- Confident AI / DeepEvalNearly every child on this page routes through Confident AI's DeepEval at some point, since a grader's own reliability has to be established, checked against human judgment, before its output counts as evidence for a claim about the system under test.
- RagasRAG Evaluation & Groundedness Testing lives under this page, and Ragas is the metric suite purpose-built for exactly that question: whether a generated answer is supported by what was actually retrieved, not just relevant-sounding.
- GalileoFor RAG Evaluation & Groundedness Testing and Bias, Fairness & Explainability Testing, Galileo's span-level hallucination detection is what turns a vague quality complaint into a precise, located claim about which part of an answer is unsupported.
- Patronus AILLM Evaluation & Benchmarking sometimes needs a comparison against an industry-standard suite, not only the client's own scenarios, and Patronus AI's benchmark evaluations are what this page's account uses for that external reference point.
Training, serving and MLOps
- DVCGolden Dataset Development needs its held-out set versioned and separated from any training split, and DVC's dataset versioning is what makes that separation claim checkable after the fact rather than assumed.
Safety and security testing
- GiskardBias, Fairness & Explainability Testing, runs its core scan through Giskard, which is what turns 'this might be unfair to some group' into a specific, reproducible finding the team can act on.
- Guardrails AIAI Launch Readiness Review and Safety & Policy Evaluation both need proof a mitigation works, not just that it exists, and Guardrails AI is where a proposed control gets run against the harm it claims to stop before it counts toward sign-off.
- Lakera GuardSafety & Policy Evaluation's retest step, confirming a fix held under real conditions, runs against Lakera Guard's live classification of refusal behavior, distinct from the original test case that first found the gap.
- MindgardWhere AI Launch Readiness Review and Independent AI Agent Evaluation need a security finding that holds up under a second, independent look, Mindgard's continuous red teaming is what supplies a reproducible attack path rather than a one-time report.
Data, labeling and development
- Label StudioGolden Dataset Development, Bias, Fairness & Explainability Testing, and Prompt Evaluation & QA all route disputed or sampled automated gradings into Label Studio for a human check, the calibration step that keeps an automated grader honest.
- Scale AIGolden Dataset Development sometimes needs more human-review throughput than a client's own team has, and Scale AI's managed workforce is what this page's account uses to keep the held-out evaluation set's quality bar consistent at volume.
- TonicWhere Golden Dataset Development needs to cover a sensitive scenario the team can't use real records for directly, Tonic's synthetic generation fills that specific coverage gap.
- JupyterGolden Dataset Development's coverage checks and LLM Evaluation & Benchmarking's score aggregation both run as notebook analysis, so the resulting numbers trace back to inspectable steps rather than an opaque calculation.
