Redis fine-tuned BiEncoder model for semantic caching on LangCache

This is a sentence-transformers model finetuned from Alibaba-NLP/gte-modernbert-base on the LangCache Sentence Pairs (all) dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for sentence pair similarity.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("aditeyabaral-redis/langcache-embed-v3")
# Run inference
sentences = [
    'The band pursued `` signals `` in January 2012 in three weeks , and drums were recorded in a day and a half .',
    'The band tracked `` Signals `` in three weeks in January 2012 . Drums were recorded in a day and a half .',
    'Contributors include actor Anton LaVey , Satanist Christopher Lee , serial killer expert Clive Barker , author Karen Greenlee , and necrophile Robert Ressler .',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.9599, 0.4944],
#         [0.9599, 1.0000, 0.5097],
#         [0.4944, 0.5097, 1.0000]])
