Rag.NET.Evaluation

Quality measurement for Rag.NET pipelines: embedding-distance and LLM-judge evaluators, A/B comparison with confidence intervals, synthetic dataset generation, and the shadow pipeline that captures production traffic for offline comparison.

Install

dotnet add package Rag.NET.Evaluation

Setup

Evaluators are constructed directly from the same Microsoft.Extensions.AI clients your pipeline uses:

using Rag.NET.Evaluation;

var evaluator = new EmbeddingDistanceEvaluator(embeddingGenerator);
// or, criterion-scored by a model:
var judge = new LlmJudgeEvaluator(chatClient);

Example

Score predicted answers against references — and make the score a regression gate in CI:

using Rag.NET.Evaluation;

var samples = new[]
{
    new EvaluationSample(
        Question:        "What is Retrieval-Augmented Generation?",
        PredictedAnswer: response.Answer,
        ReferenceAnswer: "RAG combines a retrieval system with a language model to " +
                         "generate answers grounded in retrieved documents."),
};

var result = await evaluator.EvaluateAsync(samples);
Console.WriteLine($"Mean score: {result.MeanScore:F4}");

if (result.MeanScore < 0.85)
    throw new InvalidOperationException("RAG quality regression");

UseShadow<TCandidate>() mirrors a sample of production questions through a candidate pipeline and captures both answers for later A/B comparison; RAGAS-style metrics live in Rag.NET.Evaluation.Ragas.
