This model is a 39.73% smaller version of intfloat/multilingual-e5-large-instruct optimized for Occitan language via vocabulary size reduction using the trimming method.
This trimmed model should perform similarly to the original model with only 32,768 tokens and a much smaller memory footprint. However, it may not perform well for other languages as tokens not commonly used in the selected languages were removed from the vocabulary.

Usage

python

from sentence_transformers import SentenceTransformer
# Download from the 🤗 Hub
model = SentenceTransformer("alphaedge-ai/multilingual-e5-large-instruct-oci-32768")
# Run inference with queries and documents
query = "My query in Occitan"
documents = [
    "Chunk in Occitan",
    "Chunk in Occitan",
    "Chunk in Occitan",
]
query_embeddings = model.encode_query(query)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# Compute similarities to determine a ranking
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
