SambaNova

SambaNova's Sambastudio is a platform for running your own open-source models

This example goes over how to use LangChain to interact with SambaNova embedding models

SambaStudio

SambaStudio allows you to train, run batch inference jobs, and deploy online inference endpoints to run open source models that you fine tuned yourself.

A SambaStudio environment is required to deploy a model. Get more information at sambanova.ai/products/enterprise-ai-platform-sambanova-suite

Register your environment variables:

import os

sambastudio_base_url = "<Your SambaStudio environment URL>"
sambastudio_base_uri = "<Your SambaStudio environment URI>"
sambastudio_project_id = "<Your SambaStudio project id>"
sambastudio_endpoint_id = "<Your SambaStudio endpoint id>"
sambastudio_api_key = "<Your SambaStudio endpoint API key>"

# Set the environment variables
os.environ["SAMBASTUDIO_EMBEDDINGS_BASE_URL"] = sambastudio_base_url
os.environ["SAMBASTUDIO_EMBEDDINGS_BASE_URI"] = sambastudio_base_uri
os.environ["SAMBASTUDIO_EMBEDDINGS_PROJECT_ID"] = sambastudio_project_id
os.environ["SAMBASTUDIO_EMBEDDINGS_ENDPOINT_ID"] = sambastudio_endpoint_id
os.environ["SAMBASTUDIO_EMBEDDINGS_API_KEY"] = sambastudio_api_key

Call SambaStudio hosted embeddings directly from LangChain!

from langchain_community.embeddings.sambanova import SambaStudioEmbeddings

embeddings = SambaStudioEmbeddings()

text = "Hello, this is a test"
result = embeddings.embed_query(text)
print(result)

texts = ["Hello, this is a test", "Hello, this is another test"]
results = embeddings.embed_documents(texts)
print(results)

API Reference:SambaStudioEmbeddings

You can manually pass the endpoint parameters and manually set the batch size you have in your SambaStudio embeddings endpoint

embeddings = SambaStudioEmbeddings(
    sambastudio_embeddings_base_url=sambastudio_base_url,
    sambastudio_embeddings_base_uri=sambastudio_base_uri,
    sambastudio_embeddings_project_id=sambastudio_project_id,
    sambastudio_embeddings_endpoint_id=sambastudio_endpoint_id,
    sambastudio_embeddings_api_key=sambastudio_api_key,
    batch_size=32,  # set depending on the deployed endpoint configuration
)

Or You can use an embedding model expert included in your deployed CoE

embeddings = SambaStudioEmbeddings(
    batch_size=1,
    model_kwargs={
        "select_expert": "e5-mistral-7b-instruct",
    },
)
