This model is a 23.25% smaller version of Qwen/Qwen3-Embedding-0.6B optimized for Spanish language via vocabulary size reduction using the trimming method.
This trimmed model should perform similarly to the original model with only 16,384 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/Qwen3-Embedding-spa-16384")
# Run inference with queries and documents
query = "My query in Spanish"
documents = [
    "Chunk in Spanish",
    "Chunk in Spanish",
    "Chunk in Spanish",
]
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)
