AllMpnetBaseV2Sharp

C# implementation of Sentence Transformers all-mpnet-base-v2.

Built as a modern .NET 8 class library using ONNX Runtime and HuggingFace tokenizers for correctness and parity with the original Python model.

📦 NuGet

AllMpnetBaseV2Sharp

❌ The NuGet package does not include the ONNX model or tokenizer.json. You need to download them manually from Hugging Face (see tested models below). You will need to download them manually from all-mpnet-base-v2 on Hugging Face.

By default, the embedder looks for these files in the .\model folder: ./model/model.onnx ./model/tokenizer.json

You can also specify custom file locations by setting the paths in MpnetOptions.

🚀 How to Use

Single sentence

using AllMpnetBaseV2Sharp;

var sentence = "This is an example sentence";

using var embedder = new AllMpnetBaseV2Embedder();
var embedding = embedder.Encode(sentence);

Multiple sentences

using AllMpnetBaseV2Sharp;

string[] sentences =
{
    "This is an example sentence",
    "Here is another"
};

using var embedder = new AllMpnetBaseV2Embedder();
var embeddings = embedder.Encode(sentences);

Custom ONNX model (advanced)

var options = new MpnetOptions
{
    ModelPath = "path/to/model.onnx",
    TokenizerPath = "path/to/tokenizer.json"
};

using var embedder = new AllMpnetBaseV2Embedder(options);
var embedding = embedder.Encode("This is an example sentence");
