To install voyage library:

# Use pip to insatll the 'voyageai' Python package to the latest version.
pip install voyageai

let’s use one of the embedding model voyage-2 and see its output:

# Import the 'voyageai' module
import voyageai

# Create a 'Client' object from the 'voyageai' module and initialize it with your API key
vo = voyageai.Client(api_key="<your secret voyage api key>")

# user query
user_query = "when apple is releasing their new Iphone?"


# The 'model' parameter is set to "voyage-2", and the 'input_type' parameter is set to "document"
documents_embeddings = vo.embed(
    [user_query], model="voyage-2", input_type="document"
).embeddings

# printing the embedding
print(documents_embeddings)

########### OUTPUT ###########
[ 0.12, 0.412, 0.573, ... 0.861 ] # dimension is 1024

Anyscale endpoints works with OpenAI library:

# Use pip to insatll the 'openai' Python package to the latest version.
pip install openai

let’s use one of the Text generation LLM and see its output:

# Import necessary modules
import openai

# Define the Anyscale endpoint token
ANYSCALE_ENDPOINT_TOKEN = "<your secret anyscale api key>"

# Create an OpenAI client with the Anyscale base URL and API key
oai_client = openai.OpenAI(
    base_url="https://api.endpoints.anyscale.com/v1",
    api_key=anyscale_key,
)

# Define the OpenAI model to be used for chat completions
model = "mistralai/Mistral-7B-Instruct-v0.1"

# Define a prompt for the chat completion
prompt = '''hello, how are you?
'''

# Use the AnyScale model for chat completions
# Send a user message using the defined prompt
response = oai_client.chat.completions.create(
    model=model,
    messages=[
        {"role": "user", "content": prompt}
    ],
)

# printing the response
print(response.choices[0].message.content)

What’s Next

There are many more APIs you can explore through Hugging Face Spaces. Many SME companies provide powerful generative AI tools at a very low cost, such as OpenAI embeddings, which cost $0.00013 for 1K/Tokens. Make sure to check their licenses, as many free APIs in the free tier either limit per day requests or are for non-commercial use.
