About
[!warning] Important
We recently released the next generation of this model available at:
This is a sentence-transformers model trained. It maps sentences & paragraphs to a 1024-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.
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("PartAI/Tooka-SBERT")
# Run inference
sentences = [
'درنا از پرندگان مهاجر با پاهای بلند و گردن دراز است.',
'درناها با قامتی بلند و بالهای پهن، از زیباترین پرندگان مهاجر به شمار میروند.',
'درناها پرندگانی کوچک با پاهای کوتاه هستند که مهاجرت نمیکنند.'
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]
# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

Using it via the API
Once AxForge deploys tooka-sbert for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (tooka-sbert below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/embeddings \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"tooka-sbert","input":"text to embed"}'
