RecursiveAI.OneNLP.Models.Embeddings

spaCy-class NLP for .NET. The default English sentence embedder for RecursiveAI.OneNlp: add this package and Nlp.Embed turns text into a 384-value, unit-length vector. No downloads, no native code, NativeAOT and trim clean. Unaffiliated with other projects named OneNLP.

Measured. Vectors match sentence-transformers 6.2.0 to a maximum absolute difference of 4e-7 over 2,103 texts, with no token-ID mismatches, and mteb 2.27.1 scores equal the same-harness sentence-transformers scores on every task: STSBenchmark 85.86 (model card 85.86), TwentyNewsgroupsClustering 48.63 (48.52), TwitterSemEval2015 73.24 (73.33), AskUbuntuDupQuestions 62.58 (62.59), SciFact 71.27 (71.28). Banking77Classification is 81.75 against the model card's 85.74: sentence-transformers itself misses the card by the same amount on that task, so the gap is in the card's number, not in the runtime. Size: 127.6 MiB of weights. Lineage: the authors' weights (MIT); nothing is trained here.

using RecursiveAI.OneNlp;

float[] a = Nlp.Embed("how do I reset my password");
float[] b = Nlp.Embed("I forgot my login credentials");
float cosine = a.Zip(b, (x, y) => x * y).Sum();   // vectors have unit length

The model is BAAI bge-small-en-v1.5 (MIT), exported to ONNX from the authors' published weights and run on OneModel; nothing is trained here. Vectors match sentence-transformers to float tolerance (docs/embeddings.md in the source repository has the parity and MTEB results). PROVENANCE.md states the licence and the authors' training data.
