Compute correctness
3 Step
Store and notify
Reads the evaluation dataset and triggers from the evaluation path or normal workflow, preparing questions and references for scoring.

Overview

p

The AI agent ingests an evaluation dataset and questions, runs existing AI outputs through the evaluation flow, and computes correctness scores against references. It consolidates results across the dataset, highlighting items that deviate from expectations. It logs metrics for traceability and enables stakeholders to act on failures.


Capabilities

What Evaluation Correctness AI Agent does

Performs end-to-end correctness evaluation inside your AI workflows.

01

Ingest evaluation datasets and reference answers.

02

Parse questions and expected outputs.

03

Run AI outputs through the evaluation flow.

04

Compare outputs against references to compute correctness scores.

05

Aggregate results and identify items below a defined threshold.

06

Log results to a metrics store and notify stakeholders.

Why you should use Evaluation Correctness AI Agent

The agent replaces manual, error-prone checks with automated, traceable correctness evaluation.

Before
Manual, inconsistent scoring of AI outputs across datasets.
Costs rise as dataset size grows due to repeated human reviews.
Slow turnaround times delay product decisions.
Difficulty tracing errors to specific items in the dataset.
Inability to compare results across model versions.
After
Consistent per-item correctness scores across datasets.
Faster evaluation cycles with automated scoring.
Lower costs through automated metric calculation.
Clear traceability from input to score.
Comparable results across model versions and configurations.
Process

How it works

A simple 3-step process for non-technical users.

Step 01

Ingest evaluation data

Reads the evaluation dataset and triggers from the evaluation path or normal workflow, preparing questions and references for scoring.

Step 02

Compute correctness

Compares each AI output to its reference answer and computes a per-item score, then aggregates to an overall metric.

Step 03

Store and notify

Saves results to a metrics store and notifies stakeholders with a concise report.


Example

Example workflow

A realistic scenario showing end-to-end operation.

Scenario: A data science team runs a 50-question evaluation of a historical reasoning AI. In a 15-minute run inside n8n, the AI Agent compares outputs to references, yields a 78% correctness score, flags 12 items for review, and stores the results in the metrics repository for auditing.

FAQ

FAQ

Common questions and practical guidance.

The Correctness metric compares the AI output to a ground-truth reference for each item in the evaluation dataset. It assigns a score that reflects semantic alignment rather than surface matching. The agent supports per-item scoring and aggregation across the dataset, so you can see both local and global performance. You can customize thresholds and reference definitions to fit your domain. Results are stored in a metrics store for traceability.

Reference outputs come from your trusted reference dataset or human-verified answers. The agent reads these references alongside the questions during evaluation. You can update the references as models evolve, and the system will re-run evaluations to produce fresh scores. This ensures that correctness measures stay aligned with current expectations. All changes are versioned in the metrics store.

Yes. You can set per-item thresholds or a global cut-off, and configure how scores are summarized. The agent can emit detailed per-item reports and a concise overall score, along with failure highlights. You can also tailor the notification content to stakeholders. Threshold changes trigger re-evaluations if needed.

Data privacy is preserved by operating within your environment and using non-production datasets if needed. Access to reference answers and questions is controlled by your existing IAM policies. The metric calculations happen in memory and do not expose sensitive data beyond the evaluation results. Logs can be restricted to ensure compliance with data-handling rules. You can also configure data masking where appropriate.

The agent is model-agnostic regarding input and output formats. It supports a variety of output types, including text, structured data, and multi-turn conversations. You provide the reference definitions, and the system uses them to score model outputs consistently. This makes it suitable for testing multiple models or versions in parallel. It also records model identifiers with results for traceability.

Results are stored in a metrics repository with per-item and aggregate scores. You can pull reports into dashboards or export summaries for release notes. The agent also generates a narrative highlight of major strengths and failure modes. Stakeholders receive notifications with key takeaways and recommended actions.

The agent is designed to integrate with existing triggers in your AI workflows. It can run independently for evaluation or be triggered from standard workflow events. If used with an evaluation trigger, the agent can calculate the correctness metric and attach it to the evaluation run. When not evaluating, it can skip metric computation to save costs. This makes it flexible for both development and production environments.
