ElBruno.LocalEmbeddings.EmbeddingGemma

Local text embeddings with Google's EmbeddingGemma 2 model, ONNX Runtime, and Microsoft.Extensions.AI.

Install

dotnet add package ElBruno.LocalEmbeddings.EmbeddingGemma

Quick start

using ElBruno.LocalEmbeddings.EmbeddingGemma;
using ElBruno.LocalEmbeddings.EmbeddingGemma.Options;

await using var generator = await EmbeddingGemmaEmbeddingGenerator.CreateAsync(
    new EmbeddingGemmaOptions { OutputDimensions = 768 });

var query = EmbeddingGemmaPrompts.CreateSearchQuery("Which planet is known as the Red Planet?");
var document = EmbeddingGemmaPrompts.CreateDocument(
    "Mars is known for its reddish appearance.",
    "Mars");
var embeddings = await generator.GenerateAsync([query, document]);
Console.WriteLine($"Vector size: {embeddings[0].Vector.Length}");

The first creation downloads the pinned Q4 ONNX graph and external weights (~166 MiB) plus Google's SentencePiece tokenizer (~4.7 MB). Model files are cached under the LocalEmbeddings application-data directory. Downloads are pinned to immutable Hugging Face revisions and verified against SHA-256 hashes. Once cached, inference runs locally without sending text to a service.

This package currently supports text only. The underlying model has image, audio, and video encoders, but their preprocessing and APIs are not included here. The ONNX Q4 variant is used by default; output dimensions may be set to 128, 256, 512, or 768. Truncated vectors are re-normalized.

For setup, cache/offline use, limits, and DI examples, see the EmbeddingGemma integration guide.
