NIFE mxbai embed large v1

This is a NIFE model finetuned from mixedbread-ai/mxbai-embed-large-v1. It is fully aligned with its base model mixedbread-ai/mxbai-embed-large-v1, and can be used to perform Inference Free querying using an index made by this model. It can also be used in standalone mode.

Usage

Direct Usage (NIFE)

First install the NIFE library

pip install -U pynife

Then you can run the model as follows:

from nife import load_as_router

model = load_as_router("stephantulkens/NIFE-mxbai-embed-large-v1")

query = "What is the capital of France?"
query_embeddings = model.encode_query(query)

# Five locales near France
index_doc = model.encode_document(["Paris is the largest city in France", "Lyon is pretty big", "Antwerp is really great, and in Belgium", "Berlin is pretty gloomy in winter", "France is a country in Europe"])

similarity = model.similarity(query_vec, index_doc)
print(similarity)
# It correctly retrieved the document containing the statement about paris.
# tensor([[0.7065, 0.5012, 0.3596, 0.2765, 0.6648]])
