Rag.NET.Embeddings.Onnx

Local ONNX Runtime embeddings for Rag.NET: sentence embeddings, token-level embeddings (the input late chunking needs), and SPLADE sparse encoding — all on your own hardware, no embedding API calls.

Install

dotnet add package Rag.NET.Embeddings.Onnx

Install alongside the core pipeline package (dotnet add package Rag.NET), which supplies the AddRagNet(...) builder the generators register into.

Setup

Inside your AddRagNet(...) builder callback, point at an exported ONNX model and its tokenizer vocabulary:

using Rag.NET.Embeddings.Onnx;

rag.UseOnnxEmbeddings(o =>
{
    o.ModelPath          = "models/all-MiniLM-L6-v2.onnx";
    o.TokenizerVocabPath = "models/vocab.txt";
});

Example

Token-level embeddings feed UseLateChunking from Rag.NET.Chunking, and the SPLADE encoder produces learned sparse vectors for hybrid search in stores that accept them:

using Rag.NET.Embeddings.Onnx;

rag.UseOnnxTokenEmbeddings(o =>
{
    o.ModelPath          = "models/jina-embeddings-v2-base-en.onnx";
    o.TokenizerVocabPath = "models/vocab.txt";
    o.MaxTokens          = 8192;   // default: long-context token embedding
});

rag.UseSpladeEncoder(o =>
{
    o.ModelPath          = "models/splade-v3.onnx";
    o.TokenizerVocabPath = "models/vocab.txt";
    o.TopTerms           = 256;    // default: sparse terms kept per text
});
