pplx-embed-v1-fas-32768
This model is a 20.47% smaller version of perplexity-ai/pplx-embed-v1-0.6b optimized for Persian 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
from sentence_transformers import SentenceTransformer
# Download from the 🤗 Hub
model = SentenceTransformer("alphaedge-ai/pplx-embed-v1-fas-32768")
# Run inference with queries and documents
query = "My query in Persian"
documents = [
"Chunk in Persian",
"Chunk in Persian",
"Chunk in Persian",
]
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)
