embaas is a fully managed NLP API service that offers features like embedding generation, document text extraction, document to embeddings and more. You can choose a variety of pre-trained models. In this tutorial, we will show you how to use the embaas Embeddings API to generate embeddings for a given text.

​
Prerequisites

Create your free embaas account at https://embaas.io/register and generate an API key. 
import os

# Set API key
embaas_api_key = "YOUR_API_KEY"
# or set environment variable
os.environ["EMBAAS_API_KEY"] = "YOUR_API_KEY"

from langchain_community.embeddings import EmbaasEmbeddings

embeddings = EmbaasEmbeddings()

# Create embeddings for a single document
doc_text = "This is a test document."
doc_text_embedding = embeddings.embed_query(doc_text)

# Print created embedding
print(doc_text_embedding)

# Create embeddings for multiple documents
doc_texts = ["This is a test document.", "This is another test document."]
doc_texts_embeddings = embeddings.embed_documents(doc_texts)

# Print created embeddings
for i, doc_text_embedding in enumerate(doc_texts_embeddings):
    print(f"Embedding for document {i + 1}: {doc_text_embedding}")

# Using a different model and/or custom instruction
embeddings = EmbaasEmbeddings(
    model="instructor-large",
    instruction="Represent the Wikipedia document for retrieval",
)
