Rag.NET.Evaluation.Ragas

RAGAS-style metrics for Rag.NET pipelines: faithfulness, answer relevance, context precision and context recall, computed natively in .NET with your own chat and embedding clients — no Python sidecar.

Install

dotnet add package Rag.NET.Evaluation.Ragas

Setup

using Rag.NET.Evaluation.Ragas;

var suite = new RagasEvaluationSuiteBuilder(chatClient, embeddingGenerator)
    .AddFaithfulness()
    .AddAnswerRelevance()
    .AddContextPrecision()
    .AddContextRecall()
    .Build();

Example

Samples carry the question, the pipeline's answer and the chunks it used; metrics that lack their required fields return null rather than a fake score:

using Rag.NET.Evaluation;
using Rag.NET.Evaluation.Ragas;

RagasReport report = await suite.EvaluateAsync(samples);

if (report.Faithfulness is { } faithfulness)
    Console.WriteLine($"Faithfulness: {faithfulness:F2}");

RagAbTester compares two pipeline variants over the same samples with confidence intervals — feed it live traffic captured by UseShadow from Rag.NET.Evaluation.
