sentence-transformers object.
Sentence transformer embeddings are normalized by default. It is recommended to use normalized embeddings for similarity search.
You can also load many other model architectures from the library. For example models from sources such as BAAI, Nomic, Salesforce Research, etc. See this HF hub page for all supported models.
Here is an example that uses the BAAI embedding model from the Hugging Face Hub supported models.
