SentenceTransformer based on google/embeddinggemma-300m

This is a sentence-transformers model finetuned from google/embeddinggemma-300m on the json dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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("congvm/embeddinggemma-300M-triplet-vn-10000-20250924")
# Run inference
sentences = [
    'task: sentence similarity | query: Đất tiềm năng sinh lời cao trong khu tam giác vàng Củ Chi',
    'task: sentence similarity | query: Tiêu đề: cần tiền kinh doanh ra gấp đất bình mỹ gardern\n\n\nMô tả: - diện tích 80m2 (5mx16m), mặt đường nhựa 7,5m.\n- cách võ văn bích 200m, vành đai 3 chỉ 1,5km.\n- khu tam giác vàng của củ chi.\n- tiềm năng sinh lời cao.\n- hình chân thực, chính chủ.',
    'task: sentence similarity | query: Tiêu đề: chùa hà - lô góc - mặt ngõ kinh doanh - ô tô đỗ cửa - 17 tỷ\n\n\nMô tả: chùa hà - lô góc - mặt ngõ kinh doanh - ô tô đỗ cửa - 17 tỷ\n\n* diện tích 38m2 - mặt tiền 4.6m\n\n* vị trí: trung tâm quận cầu giấy, ngõ thông ô tô vào nhà. mặt ngõ kinh doanh sầm uất.\n\n* thiết kế 5 tầng chắc chắn, lô góc thoáng sáng:\n- t1: khách, bếp, wc\n- t2,3,4: mỗi tầng 2 phòng ngủ, wc\n- t5: phòng thờ, sân phơi\n\n* sổ đỏ vuông a4\nliên hệ duy:',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
