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("redis/langcache-embed-v3")
# Run inference
sentences = [
    'The trio has performed besides Gesaffelstein , Justice , Bob Moses and Lee Foss .',
    'The trio has performed besides Gesaffelstein , Justice , Bob Moses and Lee Foss .',
    'The trio has performed alongside Bob Moses , Justice , Gesaffelstein and Lee Foss .',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[0.9961, 0.9961, 0.9844],
#         [0.9961, 0.9961, 0.9844],
#         [0.9844, 0.9844, 0.9961]], dtype=torch.bfloat16)
