Fireworks
This page covers how to use Fireworks models within Langchain.
Installation and setup
- Install the Fireworks integration package. - pip install langchain-fireworks
- Get a Fireworks API key by signing up at fireworks.ai. 
- Authenticate by setting the FIREWORKS_API_KEY environment variable. 
Authentication
There are two ways to authenticate using your Fireworks API key:
- Setting the - FIREWORKS_API_KEYenvironment variable.- os.environ["FIREWORKS_API_KEY"] = "<KEY>"
- Setting - api_keyfield in the Fireworks LLM module.- llm = Fireworks(api_key="<KEY>")
Using the Fireworks LLM module
Fireworks integrates with Langchain through the LLM module. In this example, we will work the mixtral-8x7b-instruct model.
from langchain_fireworks import Fireworks 
llm = Fireworks(
    api_key="<KEY>",
    model="accounts/fireworks/models/mixtral-8x7b-instruct",
    max_tokens=256)
llm("Name 3 sports.")
