About
This is a CoSENT(Cosine Sentence) model: shibing624/text2vec-base-chinese-sentence.
It maps sentences to a 768 dimensional dense vector space and can be used for tasks like sentence embeddings, text matching or semantic search.

Using this model becomes easy when you have text2vec installed:
pip install -U text2vec
Then you can use the model like this:
from text2vec import SentenceModel
sentences = ['如何更换花呗绑定银行卡', '花呗更改绑定银行卡']
model = SentenceModel('shibing624/text2vec-base-chinese-sentence')
embeddings = model.encode(sentences)
print(embeddings)
Without text2vec, you can use the model like this:
First, you pass your input through the transformer model, then you have to apply the right pooling

Using it via the API
Once AxForge deploys text2vec-chinese-sentence for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (text2vec-chinese-sentence 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":"text2vec-chinese-sentence","input":"text to embed"}'
